TypeError: bpy_struct: item.attr = val: enum "OPTIX" not found in ('OPENIMAGEDENOISE')

Thank you for your excellent work!

When I run render_script.py, I get the following error. I'm using the blender.zip provided in your documentation for my Blender configuration, but it's still reporting the error. Looking forward to your answers!

Blender 3.4.1 (hash 55485cb379f7 built 2022-12-20 00:46:45)
/run/user/1011/gvfs/ non-existent directory
Error: Python: Traceback (most recent call last):

TypeError: bpy_struct: item.attr = val: enum "OPTIX" not found in ('OPENIMAGEDENOISE')

When I comment out the line bpy.context.scene.cycles.denoiser = 'OPTIX' the code works fine, but the run gets a solid grey image.

The way I get the .glb file is this:

        rgb_255 = np.round(rgb * 255).astype(np.int64)
        cloud = trimesh.points.PointCloud(vertices=coords, colors=rgb_255)
        cloud.export('point_cloud_255.glb', file_type='glb')

Where coords is the N3 point cloud position and rgb is the N3 point cloud RBG, I converted to 255 and then exported via trimesh, is this process correct?

Looking forward to your reply!

Hi @Larerr , could u please try the rendering script here https://github.com/tiangeluo/DiffuRank/blob/main/render_script_type1.py, and let me know if the results is good or bad?

I think you could change to

bpy.context.scene.cycles.denoiser = 'OPENIMAGEDENOISE'

because OPTIX is supported by the NVIDIA GPU, but you use Mac
