Does anyone know how to make an accurate 1x1x1 brick in Milkshape? I need to know so I can make the collision box for the ramp.
Did you even READ the tutorial? It says in there, and because you didn't get it the first time, here: make the dimensions 1*1*3, because for the Z dimension, it reads in thirds of bricks.
