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.

OpenPBR improvements
-View-dependent coat absorption:The coat lobe now more accurately models the absorption tinting at grazing angles, producing a slightly more realistic look. (ARNOLD-15377)

Close
SSS color matching:The SSS model has been tuned to ensure that the color of dense SSS more closely matches the supplied subsurface_color, as required by the OpenPBR specification. (ARNOLD-15328). The following images compare diffuse base color with the subsurface colors of Standard Surface and OpenPBR Surface:
- top row: diffuse with a given base_color
- middle row: Standard Surface (dense) SSS, with same color assigned to subsurface_color
- bottom row: OpenPBR (dense) SSS, with same color assigned to subsurface_color

Close
Scaling of emission luminance from nits to Arnold units:nits_per_unit was added to the options node, and OpenPBR Surface's emission_luminance (in nits) is internally scaled down by this nits_per_unit value (defaulting to 1000) to bring it into Arnold units. This ensures that the default soft-maximum of emission_luminance of 1000 nits corresponds to the former behavior of Standard Surface at emission 1. (ARNOLD-15364)
Faster startup times on GPU:We have made several optimizations to improve startup and scene update time on GPU. These improvements will be most noticeable on scenes with many objects. Startup times on Windows are also now on par with startup times on Linux. On a scene with 1 million instances, we see the following improvements when compared to the previous release. (ARNOLD-15271, ARNOLD-15279, ARNOLD-15310)

Close
Handle update for OSL shader changes:Information about shaders linked to an OSL shader is stored when using interactive render mode, so that any change in those shaders will cause the OSL shader to be automatically updated. (ARNOLD-14983)
Duplicate node name warnings:Warnings are emitted when adding a node with a name that already exists or renaming an existing node to an empty string. (ARNOLD-12596)
Bug Fixes
- KTOA-974 - Cannot connect operators
- ARNOLD-14735 - OIDN denoiser bucket artifacts during negative-AA progressive passes
- ARNOLD-15380 - [GPU] small memory leak when using AOV shaders
- ARNOLD-15384 - [GPU] memory leak each time an OSL shader is modified
- ARNOLD-15385 - Crash on standard_volume when modifying material interactively
- ARNOLD-15392 - [GPU] small memory leak when using OSL shaders
Arnoldis a physically-based, photo-realistic rendering tool that utilizes ray tracing techniques to produce high-quality renders for CG and VFX animation.Ray tracing is a mathematical algorithm (based on the Monte Carlo Path Tracing equation) that creates an image by projecting rays into a scene, reflecting them off surfaces and toward light sources to approximate the color value of pixels. Arnold utilizes computer hardware resources such as memory, multiple processor cores, and disk space to accomplish these tasks.
Arnold for Katanais a plug-in for Katana which provides a bridge to the Arnold rendering system from within the standard Katana interface.
How to use the Arnold Renderer in Katana | Setup and Configuration Guide
In this tutorial, Creative Specialist Sukrit Sachdeva walks through how to add Arnold to Katana's launcher script. You'll then go on a tour of a sample Arnold scene within Katana, previewing the Arnold-specific materials available within Katana's Network Material Node, and lights that you can create within the GafferThree node. You'll be guided through Arnold's options for render settings and finish with setting up AOVs in Arnold
