I am fairly new to rFactor 2 modding and I am having trouble trying to use the material editor when texturing my road. I am attempting to use the IBLRoad shader but when ever I try to apply a file to one of the textures at the bottom of the material editor, it seems to have no effect. When I do select a file, the preview image does not pop up as if there is some error happening. The only texture that has really worked in this shader is albedo but others seem to have no visible effect. Any help for understanding the material editor or understanding texturing in general would be greatly appreciated.
