Actually that is not what I meant. I was assuming you’re rendering the light maps, then denoise them without borders, then dilate them from the denoised image, and place them into your final light map image (atlas?).
- Using HDR inputs with precisely defined intensity is important after driver 442.50.
Yes. It’s actually always important to set the HDR intensity since that functionality existed, independent of the display driver version.
Beauty buffer values must be in the range [0.0f, 10,000.0f].
Albedo buffers must be in the range [0.0f, 1.0f].
Normal buffers can be null vector for misses and normalized vectors in camera space otherwise. (Same as an unscaled and unbiased normal map, means in range [-1.0, 1.0])
(When using the LDR mode that uses the same denoiser network now and the values must be in the range [0.0f, 1.0f] and the HDR intensity should not have an effect on the denoiser anymore. It had previously inadvertently, but that has been fixed.)
Use half input formats for better performance when you can.
- There is no way to get 5.1-like behaviour from 6 or 7 (and no way to run 5.1 on 30XX). Training dataset is different now.
Yes. Denoiser AI networks and algorithms have changed since OptiX 5.1. Performance is a lot faster as well.
