Well, I got the models into Blender and had to fill in the missing triangles. I also started to manually texture it. I attached a picture showing all I have so far. Unfortunately, it is very tedious having to fill in all of the triangles, but so far that's the only way I've found to get the models.
That's awesome, rudi
Grind Session is such a good game.
The missing triangles could very well be that it's not supporting unsigned or signed version of that setting.
You should post the 3D model file along with the picture of the broken triangles to this forum section on Xentax: https://forum.xentax.com/viewtopic.php?f=33&t=16163
He can help you out with finding the right settings and adding it to the tool
Edit: Also, for information purposes, would you mind uploading a short video or text tutorial how you got the models out of the file?
In other words, how the vertices and faces are layed out in the file.
That format isn't like anything I have seen before, so documenting it would be good.
