It isn't how much detail..
It is how many polys.
However, it just happens to be that the more polys, the better it could look.
Textures are important though.. You have to realize that.
All the prefab is, is an object with no color at all. THe textures that you put on the prefab are what makes it look good..
I'm designing a parry system for TRPG.. It is looking good right now. Just hard to balance it properly.
