Thank you for reply arran!
I can't use bump and color map, because I have to model this sphere and make the holes in it (the result is actually 3d printed structure (sphere with patterned holes)).
Unfortunately I don't have any other software and knowledge for 3d modeling, than Maya. So I can't help myself with zbrush, for now.
Is there any other way, how to model this in Maya? Would be a modeling with Surfaces better solution than polygons? Maybe something with Curves?
