I have a question regarding normal maps.
When detail is sculpted on a basic mesh say a cube the new geometry is exported as a normal map to be applied to the low poly mesh (cube) back in a 3d app to give the appearance of added depth and detail to the Low poly model… I understand this much. But one thing I don’t get is what happens if you sculpt into the cube so that if you were to line up the two HP and LP cube in a 3d app the new details sculpted would actually poke into the original cube…what would happen when the normal map is applied? Would it look wrong?
I guess what i’m getting at is are all details sculpted on high poly models supposed to be risen or “above” the low poly models to show a correct normal map?
Any help appreciated!
