Hi there,
I couldn't find topic what about same problem, so let me ask about this. I sculpted business man model. and tried bake to low poly mesh on retopo room.
but result has grey spots like this.
I thought these grey spots means not enough segment or vertex on these place. so I subdivide some meshes or move vertex to on grey spots, but couldn't remove them.
why these grey spot happen?
** SORRY ABOUT MY MESSY ENGLISH **
bisc,
