Hi,
When I apply a displacement map to a flat surface, perpendicular surfaces get effected as well. Is there a button I can click to toggle this off? It becomes more of an issue on more complex the model is with internal bosses and interior walls.
Oddly enough if the second surface is not perfectly perpendicular than it is not effected by the displacement map.
My workaround was to separate the surfaces, but for my purposes I need to rejoin them which required me to export to another program.
