I'm sitting at this every free minute at the moment and yes, UV-mapping is a sh... and sometimes a hard thing.

I can only do really easy objects, nothing which is more complex and I also have to do it again and again, because at the moment nothing works at the first attempt. Really time consumption is to start EECH every time to see if the things you made are right in the game itself.

It's sometimes very frustrating and always trial and error thing (at least for me at the moment), but after a while smaller things are possible.
