I teach some computer science courses, and, while not being a professional programmer, can usually troubleshoot applications fairly well, because I know generally how they work and have some idea of what can go wrong.
Not so with Blender. I’ve just encountered a small problem (something that should be transparent isn’t), and I’ve got no idea what might have gone wrong. Eventually someone will tell me that I need to press such and such button, but I’m wondering if there’s any way to find out a bit more about the rendering pipeline (without reading a mass of technical references) so that I have some overview of the process and some idea of what may be going wrong. Does anyone know of any useful references I might be able to look at?
