Solid Angle Katana 3.2/3.5 to Arnold 3.0.2.0 + Linux

Compatibility

• Arnold: 6.0.1+
• Katana: 3.2v1+, 3.5v1+
• Platforms:
  • Linux: x86-64, RHEL 6+ or compatible glibc
  • Windows: 7+ on x86-64, with VC++ 2015 redistributable installed
• GPU: see here for detailed information. Required NVIDIA drivers:
  • Linux: 440.36 or higher
  • Windows: 441.28 or higher

Enhancements

• Updated Arnold core: Update to Arnold 6.0.2, which features the Arnold-USD procedural, a string_replace operator, new perspective camera controls for distortion, tilt and shift, and the ability of kick to directly render other scene formats (including USD), in addition to many bug fixes. Please see the release notes here. (#452, #453)
• ArnoldUsd node and op: Although Katana can bring in USD data directly via UsdIn (or PxrUsdIn for those who compile it from the USD git repository), the Arnold procedural supporting USD is also exposed via a new ArnoldUsd node and associated op, so that users may produce the same results with Arnold consuming USD data in different DCCs. (#451)
• Support Katana 3.5 series: Katana 3.5 releases are officially supported.
• Improved translation time for instances: Generating point-based or instance-array-based instances now takes a fraction of the time scenes that rely heavily on instancing via pointclouds or instance arrays. (#335)

Incompatible Changes

• Katana 3.1 series support dropped: KtoA builds for Katana 3.1 series are no longer automatic. Please contact support if this will cause hardship for your productions.

Compatibility

• Arnold: 6.0.1+
• Katana: 3.1v1+, 3.2v1+
• Platforms:
  • Linux: x86-64, RHEL 6+ or compatible glibc
  • Windows: 7+ on x86-64, with VC++ 2015 redistributable installed
• GPU: see here for detailed information. Required NVIDIA drivers:
  • Linux: 440.36 or higher
  • Windows: 441.28 or higher

Enhancements

• Updated Arnold core: Update to Arnold 6.0.1, which features GPU support for light filters, energy-preserving rough refraction, improved Oren-Nayar diffuse and rough thin-wall transmission, improved license management, and much more in addition to many bug fixes.  Please see the release notes here. (#434, #419, #437)
• Katana 3.2 support: Katana 3.2 is now supported as an official host. (#412)
• MaterialX material export: In addition to baking MaterialX looks, the ArnoldMaterialXBake node can now bake materials, e.g. the surface/volume and displacement shaders attached to a shape, into a named material in a MaterialX file. ArnoldMaterialXAssign also more clearly differentiates between a material and a look being assigned. (#431)
• MaterialX assign improvements: ArnoldMaterialXAssign now allows selecting a specific material out of the file, rather than relying on the presence of entire looks. (#419)
• Enhanced license management: New and improved license management app. (#408, #427, #336)
• Improved GPU device selection: The manual GPU device selection (in the device area of ArnoldGlobalSettings) is improved, and error reporting when GPUs cannot be used has improved in the log. (#410)
• Curves user data improvements: User data on curves is now properly handled, even when triplicating endpoints for B-spline and Catmull-Rom bases. There is also a new operator/node for manipulating curve widths more easily, ArnoldCurveSetWidth. (#421, #380, #391)
• Installer: KtoA now is officially distributed via an installer on both Linux and Windows, with binaries signed on Windows as authentic Autodesk products. For custom/local builds the old zip and tarballs can still be generated, however. The installer will try to find (and allow the user to set) the katana location, so that it can generate a launch script which makes it much easier to run KtoA. For power users they can still use their existing launch setup for Katana, setting KATANA_RESOURCES, etc as before. (#309, #429)

Incompatible Changes

• Dropped support for Katana 3.0.x series: Starting in KtoA 3.0, support for Katana 3.0.x is dropped, but release series 3.1.x and 3.2.x are supported.
• ArnoldMaterialXAssign material parameter: ArnoldMaterialXAssign previously re-used the look parameter when assigning materials. Now that parameter is hidden when materials are being assigned and instead the material parameter is populated with the available materials from the MaterialX file. You may need to re-select the MaterialX file to get it to refresh with the new parameter. (#431)
• color_convert shader args: The args for color_convert were wrong, and reflected a much earlier version of the shader. These have been corrected, but you should set the from and to parameters manually on any existing color_convert shaders in your shader network to ensure they have correct values. (#373)

Bug Fixes

• #430 Additional AOVs not denoised by noice
• #443 Arnold crashing when using geometry.point.width on linear curves in Katana
• #373 enumerated value -1 is out of range on color_convert node
• #422 Light filters are not assigned to instanced lights
• #436 OSL array parameters not presented in the shader UI
• #438 rim_light parameter not working in toon shader
• #439 Make license manager window non-modal
• #441 Live changes of image shader on quad and skydome lights not working
• #442 Some textures not loading for hydra viewer lights
• #364 Increasing the radius of a spotlight with a gobo tiles the viewport preview of said gobo
• #405 arnoldLightStatements.lightGroup attribute is not inherited
• #440 Non-input shader node parameters (e.g. __gpu__) connected by default

  • Windows: 419.67 or higher

Enhancements

• Update to Arnold 5.3.1: Updated to Arnold 5.3.1. See the release notes for more information. (#288)
• Node creation menus and hotkeys: Two new pop-up menus have been added for easily creating Arnold nodes in the node editor (default hotkey shift+Z) and Arnold shading nodes (default hotkey alt+Z). You can enable/disable the menus, change hotkeys, and even menu colors with the environment variables KTOA_DISABLE_NODE_MENU, KTOA_NODE_MENU_HOTKEY, KTOA_DISABLE_SHADER_MENU, KTOA_SHADER_MENU_HOTKEY, KTOA_SHADER_COLOR_BUILTIN_GPU, KTOA_SHADER_COLOR_BUILTIN_CPU, and KTOA_SHADER_COLOR_THIRD_PARTY. See the README file for more information on the environment variables. (#377)
• Metadata to customize shader parameters: Placing a file named ktoa.mtd next to your custom shaders allows you to customize a few aspects of shader parameters. For example, you can construct a proper Katana ramp widget, or you can change the default value of a shader parameter, or even hide a shader parameter. For examples of syntax, please see the file ktoa.mtd in the RenderPluginsdirectory in your KtoA installation. (#86)
• Arbitrary data handling: Arbitrary data translation has improved: (#378)
  • Locations of type curves now accept uniform (face scope) and varying (point scope) arbitrary data properly.
  • All other locations properly check their arbitrary data amounts to make sure they fit within the limits of the underlying primitive. Instanced geometry will also check against the original source geometry. If you previously set invalid arbitrary data, it will now issue warning telling you so and not pass it along to Arnold.
  • Texture arbitrary data is accepted as an alias of st, as many Katana primitives now set Texture data in addition to or instead of st.
  • Arbitrary data translation performance has improved substantially and reduces time to prepare the scene for rendering when there is significant amounts of arbitrary data.
• MaterialX export: A new node ArnoldMaterialXBake will allow exporting a selection of locations with their corresponding materials, labeled with a MaterialX look. This can be brought back in later with an Arnold operator (arnoldOperator shader slot, applied to procedurals or to the globals) to apply the look. (#383)
• Arnold operator export: A new node ArnoldOperatorBake will allow exporting any operators attached to procedurals or to the global options (scene-level operators) to a .ass file. (#385)
• OSL inline shader node: The shader osl has been implemented, so you can dynamically change the code of an OSL shader and have the parameters update in Katana's UI. Currently known limitations: (#133)
  • Only int, float, point, vector, normal, color and string parameters are supported.
  • Default values are always zero for parameters.
  • Widgets are not set for color parameters.
  • Only one output parameter is supported.
  • No array or structured input or output parameters.
  • Closures are not supported.
  • Only a single shader can be defined on each node.
  • Including other header files are not supported.
  • Global variables (u, v, etc.) are not supported as parameter defaults.

Bug Fixes

• #379 Update AA_samples_max default to 20 like the core
• #382 Update renderer info and update script versions to 5.3.x.x
• #389 Katana 3.1 live rendering won't show all rendered pixels

Enhancements
- Update to Arnold 5.2.2: The core version has been updated to 5.2.2, with improved photometric (IES) light sampling, hair shader anisotropy controls, and more; see the release notes. (#352)
Incompatible Changes
- XGen multithreaded disabled: XGen is currently unstable when using multithreading, so the toggle is now removed and ignored on ArnoldXGen, and may be re-enabled at a later date when XGen handles internal multithreading better. Note that if you have multiple XGen procedural locations, that can also cause instability if parallel_node_init is turned on in ArnoldGlobalSettings, so if you experience crashes please turn that off as well. Finally, the XGen procedural in MtoA will be updated to guard against these crashes in the near future so that parallel_node_init does not need to be turned off. (#353)

Compatibility
Arnold: 5.2.0+
Katana: 2.6v4+, 3.0v1+
Platforms:

• Linux: x86-64, RHEL 6+ or compatible glibc
• Windows: 7+ on x86-64, with VC++ 2015 redistributable installed

Enhancements

• New shaders: matrix_multiply_vector and matrix_transform shaders have been brought back from the old common shaders, and a flexible cell_noise shader has been added.
• Sheen BRDF: standard_surface now has a sheen layer just above diffuse and subsurface scattering, simulating materials such as velvet.
• Texture baking: a new uv_camera has been added to assist in baking out textures. To accommodate extending borders to the edge of the output texture, rendering with this type of camera is only supported for disk renders, and only with tiling turned off for outputs (on ArnoldOutputChannelDefine).
• Performance improvements: adaptive subdivision is faster and now fully multithreaded, and EXR read performance has improved.
• Spherical light sampling: spherical light sampling (point lights with non-zero radius) has improved, showing sometimes significant reductions in noise especially at grazing angles as is common in rim lighting.
• Denoising improvements:  noice has improved in stability and flexibility of image properties, and the OptiX-based denoiser uses less memory and has fewer fringing artifacts for HDR renders.
• More volumetric AOVs: volumes now output volume_Z and ID AOVs, allowing selection of volumes in the monitor.
• Cryptomatte: Cryptomatte now ships with Arnold and KtoA, and is available by default.

Toon ID:  ArnoldObjectSettings now has a toon_id parameter, where if this is set on multiple locations they will not have an outline drawn between them, but will act as if they are the same object for toon outline purposes. Note that you can also set string toon_id arbitrary data with ArnoldUserData directly, even for just some faces on an object, to drive outlines within objects as well. (#317)
Denoiser node:  ArnoldDenoise has been added which supports both interactive (preview/live) renders with the OptiX denoiser, and disk renders with noice. It only supports single-frame denoising, and each dedicated AOV/output to be denoised will be denoised separately, but even so it vastly simplifies the workflow for setting up denoising in KtoA. (#318, #289)
Incompatible Changes

API additions
AiProfileGetFileName(): To match AiProfileSetFileName(), we now also have the corresponding AiProfileGetFileName(). (#7031)
Incompatible changes
materialx.mtlx renamed: The mtlx parameter of the materialx operator node, which should point to a .mtlx file on disk, has been renamed to filename. The old name mtlx is kept as a deprecated synonym so that existing scenes don't break. Also, if the file cannot be opened, the materialx node will now report an error (and abort the render) instead of a warning. (#7018)

Update to Arnold 5.0.2.4: The included core version has been updated to 5.0.2.4 with a handful of handy bug fixes.

Asset and sequence support for OpenVDB and standin nodes: ArnoldOpenVDBSurface, ArnoldOpenVDBVolume, and ArnoldStandin nodes and their underlying ops now use the asset plugins to resolve filenames, including frame sequences. (#262)

Gafferthree auto-wiring surface shaders to blocker shader parameter: Auto-wiring of surface shaders to various parts of a light was introduced in version 2.0.6. This version adds one more, where if a light or light filter package in gafferthree has a light blocker filter, and a surface shader slot is added it will automatically be connected to the shader parameter of the light blocker. In sum, this brings the following rules, applied in order, for auto-wiring of shaders together in gafferthree: (#266)

skydome_light, quad_light, and mesh_light: if a surface shader slot is added to the light, it is auto-wired to the color parameter of the skydome and interpreted as an importance map.

gobo: if this light filter is added to a spot_light (which is the only light that supports it), and a surface shader slot is added, it is auto-wired to the slidemap parameter of the gobo. Note this also works if a separate light filter package is created with a gobo.

light_blocker: if this light filter is added to any light (except skydome, quad and mesh lights), and a surface shader slot is added, it is auto-wired to the shader parameter of the light blocker. Note this also works for all light types if the light blocker is created as a separate light filter package, then a surface shader slot is added to the light filter package.

Global shaders update in live rendering: shaders not attached to a shape location (such as polymesh or pointcloud) previously would not update if changed during live rendering. Now any shaders force-exported (via ArnoldMaterialSettings) or set on global slots like the atmosphere or background of ArnoldGlobalSettings will update during live rendering. (#257)
Bug Fixes
#263 KTOA outputs wrong indexes for arbitrary data received from Houdini Alembics

#264 Interpret arbitrary float data with elementSize set as an appropriate Arnold type

#257 Shaders not assigned to shape locations not updating in live rendering

Update to Arnold 5.0.2.1: The included core version has been updated to Arnold 5.0.2.1 with numerous new features and fixes, including a new SSS mode, better shadow_matte, flakes shaders, a new car_paint shader, frustum exclusion of subdivision and much more. (#233)
GafferThree light packages: It is now easier to create typical lighting setups by using gafferthree light packages; these are available in the add submenu in the light list in gafferthree nodes. Packages included: (#231)
Spot lights: vanilla, with gobo, and with barn doors
Quad lights: vanilla, and with image
Skydome lights: vanilla, with image, and with physical sky
Mesh lights: vanilla, and with image
Other lights: cylinder, disk, distant, photometric, and point lights
Allow arbitrary data to set built-in parameters: It is occasionally useful to be able to set built-in Arnold node parameters that aren't exposed or easy to override via existing nodes such as ArnoldObjectData. Arbitrary data that matches a built-in parameter by name will now set the value if it was not already set, providing a fallback mechanism. (#242)
ArnoldXGen shader assignment: A new parameter, xgen_shader on the ArnoldXGen node, is the preferred place to set the material for XGen. It will assign it to generated shapes that have no shader otherwise, but any archive elements that look for unique materials will still do so. Assigning a shader via MaterialAssign to the whole location will continue to force-override the shader on all generated shapes, which is probably not intended, but can be useful for debugging. (#243)
Display more types in the monitor: The Katana display driver now supports additional Arnold output datatypes: UINT, BOOL, RGB, VECTOR, and VECTOR2. The alpha channel for these types will be zero, and the color channels for INT, UINT, BOOL, and FLOAT will be grayscale. (#235)
Frame number on options: The Arnold options node now has the current frame declared and set (as a floating-point value), to increase compatibility with other plugins such as MtoA. (#237)
Incompatible Changes
state_float variable changes: The enum listing of which variables are available in state_float shader were incorrect. They have been fixed, but these shaders must be updated by hand to reflect the variable desired, as some that were previously available are gone and others have changed. (#234)
Nested instance user data overrides: Previously if arbitrary data was set on an instance with a source child that also set the user data, the value set on the instance would override the explicit value on the source. This is no longer the case, as usually, these overrides would destroy unique data that could be within deeply nested instance sources. Arbitrary data set on the instance will be set if that named data doesn't already exist, however. (#241)
Bug Fixes
#232 Loss of light filters during live rendering
#234 Incorrect variable listing in state_float shader
#240 Nested light instancing transforms incorrect
#241 Don't override user data on nested instances from outer instances
#243 ArnoldXGen should still find materials with custom export names

Enhancements
Update to Arnold 5.0.1.5: this core version brings various bug fixes. Please see here for the list.
ArnoldXGen, ArnoldYeti, and ArnoldOpenVDB nodes infer time samples: ArnoldXGen, ArnoldYeti, ArnoldOpenVDBSurface and ArnoldOpenVDBVolume no longer require setting time samples and other shutter information, but will instead guess them from the render settings shutter if no times are specified. (#221)
ArnoldStandin: The ArnoldStandin node has been added for easy creation of a renderer procedural location representing an Arnold .ass file. It will try to use any bounds information from metadata within the file, or from any legacy sidecar .asstoc files. It is also capable of reading .obj and .ply files as standins. (#218)
Extended controls for material export: The ArnoldMaterialSettings node can now export shaders from all ports, e.g. surface, displacement, light, etc. There is a name override for each port type. Also, material export can be deferred, which is helpful for look file baking where the materials won't be resolved until later. (#222)
Light instancing: Although Arnold doesn't support instances of lights, KtoA will now appropriately copy lights that are children of an instance source location so they can be rigged as part of an instance source hierarchy. (#149)
Nested instancing: Nested instancing, by having an instance or pointcloud (with instance attributes) child location, is now supported. The nesting can be arbitrarily deep, and any nested cycles (an instance source eventually referring back to itself through the instance chain) will be detected. (#118)
SSS irradiance shader: On the ArnoldObjectSettings node there is a control for setting a particular shader to handle subsurface scattering irradiance. This impacts performance, so use this only when necessary; at times having detailed normals and/or textures in SSS irradiance is necessary to capture a particular look for smaller-radius SSS setups. This parameter can be set using the ArnoldUserData node with location-type as well, but that method is somewhat more complicated. (#217)
Incompatible Changes
ArnoldOpenVDB nodes don't override shutter by default: ArnoldOpenVDBSurface and ArnoldOpenVDBVolume now have an override parameter for motion which defaults to off. When turned on, the custom motion time range can be applied, but otherwise will be inferred from RenderSettings. (#221)
ArnoldMaterialSettings name overrides: The ArnoldMaterialSettings node has renamed the forceName parameter to forceSurfaceName (and is updated by the Arnold update shelf script). Please use the new parameters instead, which allow overrides of each shader type. (#222)

#219 XGen and Yeti motion before frame can get cut off
