I'm working on creating a normal map for a simplified mesh based on a sculpt. I switched to cycles, checked "selected to active", made the simplified mesh active, selected the sculpt, and baked the normal map.

Unfortunately, after applying the normal map to the simplified mesh, the mesh appears to have holes in it. I've also noted that the normal map appears to be mostly green.

The simplified mesh, appearing to have holes in it, and the normal map, appearing mostly green.

I originally thought it was due to the messy topology of the sculpt, so I duplicated the sculpt, remeshed it, and tried again, with the same results.

Why does my normal map make my mesh appear to have holes in it?

  • $\begingroup$ Alright! I changed the extrusion to 0.5m, but that seems to have made things a bit stranger. My normal map looks less green though, so it looks like I'm making some progress, but something still isn't right here... $\endgroup$

  • $\begingroup$ 0.5 is probably too much. Also check the normals of your models. $\endgroup$

  • $\begingroup$ I experimented a bit, lowered the extrusion to 0.025, and things are starting to look a lot better. However, there are still some oddities. Is there anything else I can do to fix this, or will I have to turn to photoshop to edit them out? $\endgroup$

  • $\begingroup$ You can use a cage object which can be a copy of your lowpoly model with some deformation at the oddities. $\endgroup$
