I'm trying to create a normal map for a mesh with multires modifier. Here are the steps I took.
First I unwrapped the mesh and created 32 bit float 4096x4096 texture.
Then I applied multires modifier and did some sculpting on the mesh.
I then baked the normal map with following settings.
Here is what I got when I applied the baked texture onto the mesh:
There are lines in-between faces which seem to follow the subdivision of the mesh with multires modifier. Why does this happen?
Interestingly this does not happen if I set the preview count in multires modifier to 4, aka the same count as the sculpt. However another artifact becomes apparent.
There are artifacts in the form of leaves all around the mesh. Does anybody know what causes this?
