I’m too tired now to describe the problem in detail, but when I add a last ‘noise’ node (is an “add” including “strands” “strands_mask”) and ‘burn’ (the lower right “burn” node) it into the original image I get a strange square in the final composition. This doesn’t happen with the rest of the textures i use. As an example see the “Viewer” node. It sure looks like a size-problem, but I didn’t find any settings that would change the result.
Anybody got some tips what i did or what is wrong here?
