I write what i want. I have a "room" model, which i load to world. I move a camera, and object isn't move. And i want add to room 2 light (ex. one on ceiling, and other to wall). I want 4 options dor this. No lights, 1 lights on, 2 lights on, and 1 and 2 lights on together. So if I think about 2, 3 your proposytion I must have 4 lights map? And where I found samething about writing shader (hmm in open gl? ) and how merge open gl with jpct.
Thanks for your post, but I'm begginer , and I still have no idea.
