Unfortunately, the glitches stay the same, it’s like the triangles are being misinterpreted and misplaced (which are the lines in the first picture), as they are missing from the model itself (photo 1).
And as I’m writing this I found a temporary solution!
setting the trim relative error to >=1 fixes it, but it’s still a bit weird when looking up close, as it loses some definition and detail (photo 2).
Edit: It’s far from perfect and continues to break.
