I have 2 Normal Textures, one “Base” normal and another “Base+Detail” Normal, however, the “Base+Detail” normal also contains the information from the “Base” normal. Im trying to subtract the base from the base+detail to get just the detail normal.
I tried sbtracting Base from Base+Detail and then adding a Vector3 (0.5, 0.5, 1.0) which seems to come close buyt not be correct, as areas that were “divits” or “craters” now look like they are “hills” or “bumps”
