While trying to reaquaint myself with OpenGL, I came across your library. Raylib seems like a very good place to start!
While looking into the models module, I noticed that LoadCubicmap() calls GenMeshCubicmap with a second parameter (Vector3 cubeSize). I'm curious what the interpretation of this parameter is. It's clear that cubeSize.y specifies the wall height, but I'm not so sure about the other two members (x & z). Common sense tells me that they are the width and breadth of a single map cell.
Is my intuition correct, or am I way off?
