Reply To: What do green faces mean? (And No, I don’t mean “green face” as in feeling sick🤢)

I may be wrong, but my understanding is that Green faces in sculpt mode indicated non-manifold. Tab into edit mode, alt+a to deselect everything, press 2 or click edge select mode, click select->select by trait->non manifold. to verify. Faces also turn green if they are selected for free style back in 2.76, but I believe it’s just the edges in edit mode since 2.80+.
