Reply To: Issue with my model
My suspicion is that it is a result of the topology of the high-poly. You may need to go in and pull some of those edge loops a little wider in areas where you want a flatter face. It may be possible that the curvature of the faces is really pronouncing that pinch more than it would otherwise. It is a bit of a tricky area, as you want those edge loops for the creased area of the elevated tread part, however maybe a couple of edge slides will do the trick there. Maybe just do a couple and compare with a bake to see if that helps alleviate the problem before fully committing!
RE: Ambient Occlusion
That looks like it may be an issue with pixel padding, I believe SP calls it dilation. In the baking dialog window, what is the Dilation slider set to? 🤔
