Solid Angle Katana 4 (Win/Lnx) | 959 MB (Total) Solid Angle, a bussines Autodesk, has released version 4.3 of Arnold for Katana (or KtoA). This release uses Arnold 7.2.5.3 and is a bugfix release.
Solid Angle, a bussines Autodesk, has released Arnold for Katana 4.3.4.0. This release uses Arnold 7.3.4.0 and is a feature release.
KtoA 4.3.4.0 – Arnold for Katana – Date: 29 August 2024
Katana 4.5 and 5.0 compatibility
Katana 4.5v3 and 5.0v3 introduced a change that affects the Arnold USD plugins support in Katana. This release of KtoA supports those Katana versions or newer within their release series. Katana 4.5v1, 4.5v2, 5.0v1, and 5.0v2 are not supported by this KtoA release.
Bug Fixes
- ARNOLD-14563 - Remove 100000 limit on number of cryptomatte manifest entries
- ARNOLD-14732 - Render hangs when distance shader is connected to displacement
- ARNOLD-14753 - [GPU] Crash with procedurals or global light sampling with NVIDIA drivers > 550
- ARNOLD-14770 - Moving procedural child objects doesn't update procedural bounds
- ARNOLD-14794 - Setting array parameter with same value detected as modification Improved performance on Windows: Arnold now runs on average 7-8% faster overall on Windows. (core#5481, core#9876, core#9975)Improved IPR interactivity: IPR interactivity on both CPU and GPU, especially when moving the camera in a scene with many nodes (thousands to millions of meshes, ginstances, lights, shaders, etc.), is improved. For instance, a scene with 24,433 ginstances and simple shading went from 8 fps to 14 fps on the CPU and about 3 fps to 20 fps on the GPU. (core#8662, core#9918, core#10027, core#10029)Improved performance in Toon on Windows: The contour_filter used for toon rendering should now be faster and scale better especially on Windows, with up to 3x speedups on AMD Threadripper 2 and up to 4x speedups on AMD Threadripper 3 CPUs. (core#7844)Toon AOV prefix : The toon shader has a new optional aov_prefix that will be prepended to the toon AOVs' names. For instance, if aov_prefix is "toon_", the toon diffuse AOV will be written out to "toon_diffuse". This can be used when you need to access both the toon AOVs and the core's LPE AOVs. (core#9823)Improved soft creases in adaptive subdivision: Normals for soft creases follow the geometry closer for low iterations. (core#9971)
AA seed now included in EXR metadata: The AA seed of a render is now also included in EXR metadata. (core#9895)Improved support for MaterialX: Material nodes are now supported, shader nodes and node graph outputs can be connected to material node inputs. Node definitions implemented as node graphs can contain both Arnold native shaders and MaterialX standard library shaders. This is useful to build reusable and portable material groups and definitions, for example by using standard_surface with MaterialX patterns. The environment variable ARNOLD_MATERIALX_NODE_DEFINITIONS can now point to directories and load multiple node definitions (see here) (core#9204, core#9618, core#9926)KatanaUsdPlugins: A custom build of UsdIn is included with KtoA that is a drop-in replacement for the UsdIn included in Katana. It includes several changes that are to improve the use of UsdIn with KtoA. (ktoa#523)UsdIn Material Transfer: Arnold materials exported from Solaris or using MtoA's USD export are correctly imported to the scenegraph. (ktoa#488)Apps & Features Entry: The KtoA entry in Apps & Features now has a more descriptive name. (#458)Arnold-USD: The Arnold Render Delegate and Node Registry plugin is now included with KtoA. This allows the use of the Render Delegate in the Katana Hydra Viewport. (#494)Tooltip Coverage: Tooltips are correctly set for all the shader parameters. (#203)Arnold SDK: The Arnold SDK is now included within the KtoA installation to simplify building shaders, procedurals, and other plugins for the Arnold that KtoA is using. (#527) GPU Enhancements Improved on-demand loading of textures: The GPU renderer can now partially load textures which results in important GPU memory savings when using tiled and mipmapped textures, such as from .tx textures. In a typical scene, the amount of memory needed for textures could be reduced to be up to 5x smaller. A recent driver is needed for this feature (core#9984).
Initial support for light linking: Initial support has been added for light linking. Currently, there is a limitation that light linking is not supported on volumes. (core#9890)Support light AOV groups: Adding light AOV groups in LPEs is now supported on the GPU. (core#9882)Improved OSL JIT compilation performance: OSL JIT compilation performance has been improved, meaning faster time to first pixel and improved interactivity when using OSL shaders. The improvement averaged 6.3x faster during testing. (core#10004)Improved support for min pixel width and thin-walled sampling: We have improved compatibility with the CPU renderer for min pixel width on the GPU and thin-walled sampling on zero roughness surfaces. (core#9291)Partial GPU IPR output: Like on the CPU, when the FPS goes below a certain threshold (5fps by default), instead of not displaying anything, the GPU will at least display the pixels that have finished rendering. Since GPU currently renders pixels in a top to bottom ordering, this will result in the top part of the image being updated while the lower part becomes stale. (core#10027)OptiX cache location change: The Optix cache directory used to be of the form: arnold-<ARNOLD_VERSION>_driver-<DRIVER_VERSION>. Now it is simply arnold. This means the same cache will be used across driver and Arnold versions. Upgrading to a new version will still likely cause a lengthy JIT/cache pre-population, but it will reduce disk usage as old versions will not stay around-consuming disk space. (core#9239). USD enhancements Light Shaping: The procedural now supports the UsdLuxShapingAPI, allowing the use of spot and IES lights (usd#344).UsdTransform2d: The render delegate now supports the UsdTransform2d preview shader (usd#516).Per-face material assignments: The render delegate now supports per-face material assignments (usd#29).Render Stats: The Render Delegate now returns render stats via GetRenderStats. For now, this is used to show render progress in Solaris (usd#537).Schema for custom procedurals: The schemas now include ArnoldCustomProcedural for describing custom procedurals (usd#487).Schema updates: Schemas now support cameras, render settings, and new output types (usd#500).Parent Scope: There is a new flag to specify a custom root for all exported prims (usd#292).ST for Texture Coordinates: Texture coordinates are now written as primvars:st to match the USD convention (usd#542). Incompatible changes Correct refractions with nested dielectrics: Refraction through adjacent transparent media now looks more physically correct thanks to nested dielectrics resulting in a look change. If you need to revert to the legacy unphysical behavior for compatibility reasons, you can disable nested dielectrics globally by setting options.dielectric_priorities to False.mix_shader add for transparency: Previously, the add mode of the mix_shader also added the transparency closures, which means that effects such as min pixel width would be double-counted, leading to objects disappearing. Now, we will add only non-transparency closures, while we pass through the max of the transparency closures. The old behavior can still be obtained by setting add_transparency to true (core#9952). Skipped node updates: In order to improve IPR interactivity, we skip the per-frame node update if we believe that node has not changed. If our internal heuristics for detecting node changes is wrong and node_update was supposed to be called, you can set the force_update metadata on your node:node_parameters{AiMetaDataSetBool(nentry, nullptr, "force_update", true); // depends on camera node// …} so that Arnold will always run node_update on every render pass. At the moment, this should only be needed for nodes that access options.camera in their node_update. If you do not have access to your shader's source code, you can globally disable this optimization by setting the options.enable_fast_ipr to false (core#8662).
