Glass issues

[ajrf]

Hello.

I've realised that in some tracks, when I launch a certain car (with the dirty windscreen activated), the windows are all in black as shown:

But, as happens in this picture, this doesn't happen in all the tracks:

I hope that anyone here can give me any solution to fix this.

Thanks in advance.

Sometimes when a track has a material named i.e GLASS and your car also uses this name they cause conflicts. The answer is to find the conflict and rename one of them.
Make sure the glass in the car is called windscreen for instance.
It will take a bit of searching to find the culprit.
