The only way to make bricks is to write in the coordinates for each vertex, normal and UV of each face into a .blb file which you can open in notepad. Have fun.
Whoa, after reading that the text in the notepad makes more sense, but still complex overall. It'd be nice to have a 3D example to a ramp brick written code on the images. I understand some of it but I'm at a complete lose on where these cords are. But I guess I don't want to spend hours trying to work it out.
