My lightbar is weird

  • So I was done with the car i saved all of the textures into a folder then I made a ytd put all of the files in there then I made a ytd+hi and put everything in there aswell then I put the hi files into open IV and my lightbar is weird like if it was a texture problem but in zmod it was normal what's the problem? I also converted them into pngs so maybe do I have to put the dds files into the ytd or what?
