Denoise Node

Yeah but something proper like the optix/open denoise seen in blender would be much more efficient maybe?

Hello,

In addition to raising the amount of samples, a good way to denoise without losing quality is supersampling: compute the node at a higher resolution then downscale the result using a Transformation 2D node.

Also, make sure the bitdepth of the input height map is at least 16-bit to model smooth gradients..

Best regards.
