I'm encountering an issue when rendering with Arnold in Maya 2025 using GPU and the OptiX Denoiser.
Here's the setup and problem description:
- My scene consists of 42 frames.
- I'm using multi AOVs for compositing: RGBA, N, Z, AOCC, diffuse, coat, specular, transmission, and volume.
- To denoise all AOVs, I specified *"RGBA or " in the Layer Selection field of the OptiX Denoiser attributes.
- I followed the guidelines to set the output to EXR and turned Merge AOVs off.
The problem:
- Only RGBA, N, Z, and AOCC AOVs render correctly. The other AOVs (diffuse, coat, specular, etc.) either render corrupted files or do not appear at all.
- Rendering stops after just 1 frame for AOVs-enabled render layers.
- If I disable all AOVs and render only the Beauty (RGBA), it renders correctly from frame 1 to 42 across all frames.
I'm using GPU rendering with the OptiX Denoiser, and my settings include EXR output without Merge AOVs, as recommended in the documentation.
How can I resolve this issue and ensure that all AOVs are correctly denoised and rendered over the full frame range?
Any help or suggestions would be greatly appreciated!
