What caused these normals to get so messed up?
It looks like A) your LO poly may not be aligned well enough with your HI poly or B) your sculpted accepts changed the broad shape of you HI poly too far away from the LO poly. Either way I demonstrated a way to refine the threshold of baking during the week 3 stream.
Make sure to thank @duerer and @spikeyxxx for their insight and attentiveness 🙏
