I downloaded a dev CVPI and added it to openiv which the .yft file opened just fine and worked in-game just fine. I added an els gta iv converted code 3 x2100 lightbar to it and then tried opening the .yft file in openiv and nothing happens. No windows opened, no errors or anything. (.ytd file opened without issues) I tried spawning it in-game and nothing would happen to a point where I had to force stop GTA V. The only error I got when exporting from zmodeler was "Can not obtain Shader material from "Default Material". file:RageExportMaterial.cpp line:126" and some errors that say "mask should be *this*" or some stuff about textures.
The issue arose only when I added the converted light bar. Did I convert it wrong? Or export it wrong? Any ideas?
