Help with GTL-gtr2 coversion mod

[monzagtracer]

I'm trying to convert a porsche 934 mod from gtl-gtr2 . I can get the description to show up in the menu, but no visual image. I have done all of the .gtr, _gtl.gtr conversions. I also did the tex.gtr in the .car file. Do I need an ultra-tex file as well as a tex file in the .car file?
