novice here. I want to make 3D mattress, and I want to simulate the mattress cover like on this picture:
I want to add this little holes symmetrically around my cube. What is the easiest method to do this?
you could use a displacement map, maybe you could get away with using a normal map, depends a little on where you want to use that mattress (in a game or in an offline rendering)
or maybe, if you are crazy, you could even sculpt it, make yourself a brush tip in that shape.
