This is a strange one, though one rather simple to explain.
When I try to render an object from a heightmap using micro displacements, it skews the bumps upwards and away from the surface, rather than straight out. I at first assumed it may have been a problem with the heightmap, so I displaced via the modifier, and it came out looking just fine.
The one thing I’ve noticed is that I can’t set the vector displacement node to UV, only tangent, object, or world. This might be the root of the issue, I’m not sure. Whatever the reason, I’m coming to you all for help yet again, cuz I can’t figure it out.
To illustrate what I mean, here are two shots showing off two methods, and their end results. The top one is standard modifier displacement, the bottom one micro. What am I doing wrong here?
