Does anyone know if it would be possible to place randomized 1" spheres in a specified area within MoI. Think about a gumball machine for what I am thinking. I tried it with a very poor res texture and it looks terrible. 1st attached image.

I have done a manual placement before but getting it random was impossible, so I left then layered. 2nd attached image.

I would really like to get them randomized without all the effort in the 1st attached image shape.
