Hello, I had a problem when doing the retopo and now on the eyelid there is a concavity because I added, with multires on, new vertices to the retopo mesh to fix that little "hole", is there a way to fix it? Because I know, now, that multires uses the same amount of vertices from where I copied the high res details. Thanks
Hi Fabrizio - Generally I recommend to avoid changing a multires basemesh for the sake of maintaining vertex count. Usually such changes risk exploding meshes. BUT Blender's multires can actually be fairly robust. So depending on the prominence of the chance, you can often get away with small mesh changes.
However I need to know more about your specific situation. Can you elaborate on the steps your taking and include screenshots?
