Short description of error
I worked some weeks on this project here: http://bit.ly/2FKTU0p
While the development I made interesting experience with the denoiser. Below you see an example what happen, when the denoiser is used with different values. What I do not understand are some points.
Why is the denoiser producing artefacts when using bump textures? My experience with diffuse and regular textures without any bumpmaps are well and mostly without any artefacts. As soon as bump maps or normal map informations are added, blender produces ugly artefacts like you see in my example below. It could be just a feeling, but I think bump maps and denoiser are not good friends...
Here are some settings with an image of a part of my scene to compare what happen. My official settings I am using are on the left hand in the shot.
The lower the radius the more splotches appear. They look like photon spots but are coming from the denoiser only. I've rendered the part with a very high resolution without denoiser to see if there are any photons visible, but all looks well.
Basically the smaller the radius in my experience the more splotches appear. And you can not improve it by experimenting with the options. Of course I get more details, when I use a smaller radius, but the artefacts overweight. So in my case I decided to use the highest radius, to get a smoother result. But even there are some splotches.
Is the denoiser still in development and can I expect some better results in the future?
