GPU Texture Format

Rendering using - Production engine GPU CUDA

According to the manual the GPU Texture Format ? Controls the file format of the textures used in GPU rendering. You can choose between 8 bit, 16 bit and 32 bit.

So most of the time textures that I use in shaders are 8bit, but I also use a lot of 32bit HDRI EXR textures on lights, such as for a VRayLightDome, when I want an HDRI lighting solution.

So do I need to keep the GPU Texture Format at 32 bit if I'm using 32bit HDRI EXR textures on lights, when rendering using GPU production renderer?

Thanks!

Yes, in your case you can leave the format to 32 bit. This option is a maximum resolution limitation, everything above this value will be compressed.
Just make sure you have enough GPU memory to handle the job.

V-Ray GPU will always use HDR textures for lights and displacement. The GPU Texture Format option is affecting just the materials textures, so you can leave that at 8bit.
We will update the docs!

Best,
