Katana 4.5 and 5.0 compatibility
Katana 4.5v3 and 5.0v3 introduced a change where the Arnold USD plugins support in Katana. This release of KtoA supports those versions or newer within their release series. Katana 4.5v1, 4.5v2, 5.0v1 and 5.0v2 are not supported with this release.
Enhancements
- Partial and resumable renders improvements: For disk/batch renders, KtoA previously used a transient mapping file on disk next to the temporary render files, but this sometimes caused collisions with different KtoA render processes from different machines on network shares. KtoA no longer uses this mapping file. Partially-rendered files are now copied to the final location, even if the render process crashes or is otherwise prematurely terminated so that partial results can be viewed. Partial renders can be resumed by enabling ArnoldOutputChannelDefine > append and the render started again. (KTOA-826)

System Requirements
Windows 10 or later.
Linux with at least glibc 2.17 and libstdc++ 4.8.5 (gcc 4.8.5). This is equivalent to RHEL/CentOS 7.
CPUs need to support the SSE4.1 instruction set.
GPU rendering works on Windows and Linux only and requires an NVIDIA GPU of the Ampere, Turing, Volta, Pascal, or Maxwell architecture. We recommend using the 495.46 or higher drivers on Linux and 511.09 (Quadro), 511.09 (GeForce), or higher on Windows. See Arnold GPU for more information.
Optix™ denoiser requires an NVidia GPU with CUDA™ Compute Capability 5.0 and above.
The driver type must be set to DCH.
In the driver page, select "Windows Driver Type:" DCH
The cache will also need to be re-populated after installing a new Arnold version, updating to a new NVIDIA driver , or changing the hardware configuration of GPUs on the system. More information can be found here .
Katana Katana 4.0v1 or newer, Katana 4.5v3 or newer, or Katana 5.0v3 or newer.
