I have recently added a lightbar to a merit and now i want to make textures for it. I actually managed to get a template.png for it and made a simple test texture but i do not know how to add it into my .wtd file as there isint any paintjob textures in it. Can anybody teach me how to add it in and make it really show in the game? Thanks in advance.

I tried your tutorial. But the problem now is when i clicked on material editor, a message pops out and say " out of memory" What can i do?

seems like running zmodeler as administrator works
