I want to add some knolls onto a ground surface by using textures. Currently it looks terrible and I don't know how to integrate it properly.
What is the best procedure to do this? At the moment the stones do not look integrated into the knoll, there is a sharp border around it and it does not look natural.
I would like to use the bump map of the stone texture and then to texture paint over this bump with the sand texture stamp. How can I realize this in blender?
Additionally I want to work in Cycles. Does it make sense to create the textures in Blender Internal mode at first and then add the created texture to a material in Cycles mode?
I suggest this method because the handling of texturing is much easier in Blender Internal than in Cycles.
The current picture is like this:
