Is it possible to add (or blend) a texture in the shaders to steep= gray instead of calculating a 'simple colour cloud'? In combination with a texture it probably looks like all the 'perhaps' and is a very nice feature. Here recent 'steep = gray'-blobs do not look like rock or rock run or something else at the moment - sorry for my misunderstanding. I see that some landmass reliefs are calculated also with snow. So it should be possible to add a texture to the 'steep=grays' or not?
