How do I make 3D MDL files for pumpkin's 3D engine?

Hey Pumpkin. I just want to know how you created your mdl files for your 3D engine. I just want to know what engine you use to make the models.


Also a quick note, if you dont know which one I’m talking about. Its the one with the 3d model of yourself and the teapot, Thanks.

i think i made the mtl files from the blender obj export. and i may have manually edited the file afterward. It is also entirely possible i wrote them by hand.

How do I do the rotation thing for when you turn back you cant see it but when you turn to face it you can see it, how do I do that with 2D drawings? I’m actually quite confused xD
