Hi all together! I just started to make custom skins for rFactor 2. But I faced some questions. At the moment I'm trying to build a custom skin for the Porsche 991 RSR. There are 3 template files one for the whole car and 2 for the windows. The window files are called in and out in the end. Am I right that they are for the inside and outside view of the vehicle? I replaced the Porsche reading on both files and converted them to .dds. I put all 3 files to a mas file and placed it in my loose livery directory for the Porsche. So now the problem I faced. The outside view of the Porsche is like expected but from cocpit view I still see the Porsche reading on the window. What did I wrong? My loose livery directory looks like that: -alt.mas -- alt.dds -- alt_windowsin.dds -- alt_windowsout.dds I hope my problem is described propper. If you see any other errors in my doing please let me know. As I said I'm just at the beginning. Thanks for your help.
