My grandson Vincent wants to make 3D models of robot-like characters he created for a game. I only have experience with Poser so I need some advice from more experienced 3D people to steer him in the right direction. I know that Zbrush and Blender are modeling programs but I have no idea if they are what he should get. Is one more user-friendly? Is there something else with a shorter learning curve that would get him reasonable results? We are open to suggestions and appreciate all help.
