Hi @tiborbleuel thanks for the complement, your mountain looks great too, is this a dynamic topology sculpt?
I’ve retopologized mine to very few polygons (190) and tried to add detail with a mulit-res sculpt as demonstrated by Kent on Thursday. When I try and bake the normal map the I get strange colours or nothing at all. I don’t know how large you have made your mountain but it looks like it a fair few Blender units like mine is. The only way I have manged to get any sort of normal map from a multi-res sculpt using the bake from multi-res option was to scale my mountain down to the same size as a 2 blender unit cube. You’ll have to let me know how you get on when you retopo yours and do the multi-res sculpt.
