I figured it out: if you have secondary headlights that belong to the vehglass material, they use the Same window tint as the car windows.

By default, the rancherxl comes with dark windows which also makes these headlights appear black.

I changed the window tint level of the rancherxl in vehicles.meta, now that issue is gone.

Thanks for the tip, now I finally have the body material bug sorted out.

But when it comes to the headlight issue: that is still there although I changed the order as you told me (the secondary headlights belong to the bodysheel)

And now, I've run into a new problem: the normal headlights light up when I just enter the car, even if it's daylight. In the night, the head and rear lights are very bright as if the lights were turned on.

Can anyone help me with that?

Thanks

Hey guys,

I've been trying to convert Thundersmacker's Declasse Yosemite truck to GTA V because it fits so perfectly in the game. It's my firts overall conversion of a GTA IV Car to GTA V which I did with knowledge entirely based on YouTube tutorials.

@Thundersmacker: Thank you very much for your permission to share this awesome truck to GTA V players!

The truck is drivable and works in GTA V; it even has a next-gen interior in it:

Unfortunately, I still have a few bugs with the truck which I can't fix myself. Here's what still needs work:

• Body material (when I shoot at the car, the body looks like it's made from wood)

• Black headlights (there is a pair of "secondary" headlights under the primary ones which appear fine in Zmodeler and OpenIV but totally black in the game)

• The inner side of the car doors are still from GTA IV because I can't model new doors from scratch or change the Rancher XL's doors so that they fit.

And this brings me back to my original question: Is anyone with better Zmodeler skills interested in helping / supporting me to get these bugs out of the way? I'm glad to provide you with all the project files I still have.

Thanks a lot and all the best,
