After making significant changes to a material it now shows as having this weird stretching effect in certain areas usually at the edge of a mesh. Below are screenshots of the issue and the material nodes. Any explanation for why this is happening?
first of all, roughness shouldn’t just be a scalar value, but an accurate roughness representation texture to get proper light reflectance. (makes my ocd tingle)
your normal map should use the world aligned normal node instead of world aligned texture.
also, because its world aligned, certain angles will look stretched as the node doesnt know if it should apply the material on the X, Y, or Z axis. these nodes work best on almost flat, non-diagonal surfaces.
your texture-size is also very small, resulting in loads and loads of tiling.
