Ok I had the problem of it corrupting but it got fixed by using ,dds but there is no texture to the lightbars in Zmodeler or in OpenIV or in game.

I have tried deleting and re adding textures but that did not work. Any help would be appreciated

could you add some screenshots, and be sure that all the textures work in zmodeler, otherwise they wont work in openiv or ingame

i have never had an issue with using png, if thats the issue then thats really weird. did you map the lights in the textures editor to each lightbar? if they all use the same emerglights then you will get gray lightbars. if you need any help, send me a private message ill be happy to help you fix this issue :)
