Here is a very simple tutorial for those with minimal coding knowledge. If you're fluent a bit with python(lua can help too), it should be very hard to grasp. I made a few mistakes with the original program when trying to add keyboard input, therefore, I just started a new python program and show how to load a custom terrain(made with blender). I might have other tutorial videos uploaded later. Ill also try to put up some character avatar tutorials too. Also, it might look like the model is rendering weird(that's mostly because of Backface Culling, a rendering optimization technique in modern game engines.)
