When I try to render with my GPU on the Optix option in Blender I get an error message that says. "OptiX backend does not support 'Ambient Occlusion' and 'Bevel' shader nodes yet.
Is it possible to do it or not? Can anyone help me?
Thanks in advance
Everything is in the error message. No you cannot as Optix doesn't support these nodes. You must switch to CUDA.
Lucky, Blender 2.92 will be finally released on 24Feb and it will support AO and bevel shader nodes with Nvidia Optix.
I tested on 2.92 alpha and confirmed okay. The rendering time is reduced significantly. 😄
You may refer to the release notes: https://wiki.blender.org/wiki/Reference/Release_Notes/2.92
Blender 2.92: Cycles
GPU Rendering
- GPU devices can now take over tiles that are currently being rendered by CPU threads to improve hybrid rendering performance. (517ff40b12)
NVIDIA OptiX
- Hybrid rendering with CPU and GPU devices is now supported. (bfb6fce659)
- AO and Bevel shader nodes are now supported. (c10546f5e9)
- NVIDIA driver version must be 450 or newer, due to an upgrade to OptiX 7.1. This makes it possible to render more object instances.
That is good news.
Thank you for your help.
