@OhiOcinu You mean that you want remove tint from windscreen or if you change the tint windows become fully black, no matter which level of tint you install? In both situations its depending from vertex painting. Also i recommend use default glass texture from vehshare.ytd To fully remove tint from window select desired window, go to vertex mode, select all vertices, go to surface > paint > A channel > set color to fully black > fill selected. If you just want to lower tint level try something like gray color
Had it working properly now. Just have to change the detail of the windows. Thank you very much for the help!
