Optix Denoise error on large maps #123

Open olliebarbs opened 3 years ago

Any idea what may be causing light maps to be coming out as is shown in the attached image?

LM_Optix_Error

Saved this to a jpeg for size reasons so hopefully it still shows the issue.

The non denoised image looks like this:

Plane_baked

It seems to happen for me on images above 4096 px when using the optix denoiser. I thought it may be a memory issue but on inspection of the RAM usage it seemed to be within limits. I have also tried using the odin denoiser but this seems to result in a different error.

I'm using Windows 10, Blender 2.93.4 and addon version 0.5.5.0

Thank you so much for your hard work on this addon, its is an amazing tool so far and makes something that was so fiddly before so much easier.

Thanks for reporting this bug!

Does this mean that this only happens on images that are 8K and 16K on both Optix and OIDN?

It seems to happen on 4k images and above. Odin seems to not generate an image and results in the objects showing the pink missing texture colour
