I think I found where it hangs...
This works, a long as there is no other car using the same texture.
If I'm alone on track with "luce6" and "___style3" rims, it's OK.
But when other cars are on track with the "standard" style3 rims, then my car is also getting the standard "style3" rims :/
I wanted to change the texture in the .gmt files, but I had a new problem.
In some cases it's easy to find which .dds is related
In this case, I changed from 300.dds to 600.dds
But how can we now which .dds is behind this (3, 300, 301, 302 ???)
When we click the button, the old value dispear, no chance to catch the old value.
