I think the problem is that the two objects have the same size, and pretty much the same shape, but I don’t know what to do, should I always scale the High Polly?
(I have modified the “max ray distance” to different values from 0 to 1, but on all the values the result is the same)
You might have a duplicate mesh. Go into edit mode and tweak one of the vertices to se if you do, then, if so, ctrl L and delete. Or remove doubles, whichever.
Thank you for your answer, unfortunately no, but, the problem it’s for the HP faces, being in the same place and shape as the LP ( I have scalated a little the HP and the problem solves), but I don’t want to need to scale to bake, I feel that it’s not a solution and I am doing something wrong.
(the HP and LP are pretty much the same shapes, just small changes in some parts)
