So I've just imported a regular 2008 CVPI with nothing added and with all of the correct textures imported. When I export everything else, that car is fine. But, when I export the CVPI with nothing added it shows that the cv_stuff doesn't suit settings for gta_vehicle_generic. I'm not sure what the problem is.

 

Note:

I had to delete cv_stuff_b out because it wouldn't let my livery show

too me it dont mean nothing i guest just reload all your texture and then export it one more time and should bee it good work on me

I get that error, it doesn't affect anything for me.

It means exactly what it says.

 

It's telling you that whatever material you have the "cv_stuff" texture mapped to is set in the materials editor to be use the "vehicle_generic" shaders, but the material isn't configured properly for those shader settings.

 

The error most likely won't negatively impact anything, since GTA will automatically use the "default" settings. But, if you want to get rid of that message, just look through the material that uses that "cv_stuff" texture and reconfigure it in the materials editor to be set up properly. Here's a tutorial on material set up: http://www.lcpdfr.com/page/tutorials/index.action/_/texturing-tips-and-tutorials/gta-iv-material-types-and-setup-r103

 

If it's a yellow exclamation point for your error, don't worry about it. Put it in your game and it should work fine.
