I see what you did, you basically have a model that has welded vertices connecting more than 1 plane facing different directions etc, and you copied the specific faces, and re pasted so its on its own group, and then delete the original, thus removing the shared vertices....right? BRILLIANT. I think you now taught me what the heck has been going on with my models over the years lol.

I have focused my entire career to coding and getting a game to a functional point...now that I am here I am learning so much about the finishing touches. I still need to learn shaders and special edge blending lol.

This is probably way off topic, but if anyone has tried this, it would be you Superku. Is there a way to make like a light outline around a certain model? Say for instance in your model above, if you wanted to have a red outline around the model outside edges, does this game engine support such a thing?
