Hi Kaus, I tried it again but this time with light. I put light2.png in the parallaxes folder, put the light tag in the map note, then i run the game at that map and it load forever, when i try to close the game, nothing happen, my cursor freeze and nothing i can do. I can only shut down my computer and start again. You ask me to try again; done. You ask my specs: Intel Core i5 8gb ram win 64 gfx card GeForce GTX 760 Thank you for your work! Sad to get that problem, i was really expecting to use overlay mapping. EDIT: I did it again with 1.07, same thing. But i manage to close the game without computer freezing, but i has to wait a bit until it close. Is it because my game start on a 250x250 map? EDIT2: Ok i tried it on a 50x50 map and it work like a charm. No heavy loading was felt. So i wonder what can happen with the other map (250x250)... I can live with it, i'll make my other map smaller with more zone transfer.
