It's probably not that common, but still, if there's no reason to not have it we might as well support it. Also, removing the type option makes device selection easier - users don't care about CUDA or OpenCL, they just want to select their card.

Lukas Stockner (lukasstockner97) added a comment to T56175: Bug in glossy shaders with the new reflection fix to Bump and Normal Map nodes.

The problem here is that the correction code tries to get a reflection ray that is at least ~3° above the true geometry. However, we can get the case that the reflection will be below that even if the bumpmapped normal is exactly identical to the geometric normal by simply looking at the surface at a shallow angle.

Lukas Stockner (lukasstockner97) added a comment to D3495: Cycles Gabor Noise Texture Node.

Some questions from checking the code:

  • Do you think it is important to expose frequency, bandwidth and truncate? If not, you could get rid of GaborParams, just store impulses, lambda and sqrt_lambda_inv in a float3 and hardcode the others.
  • Is there any use case where the user would want to control the seed based on some texture etc.? If not, just making it (and maybe scale) fixed parameters instead of input sockets might be better (see e.g. the sample parameter in the recent AO node commit).
  • What range does the impulse parameter typically have? If it's fairly large, some other poisson sampling method might be a better choice.
  • Does quick_floor really make a noticeable difference?
