Hello. I often work with curved surfaces, and I’ve noticed that the accuracy of the obj export suffers a lot - it’s like I’m modeling at level 4 subdivided, but some surfaces are exported at level 1, which creates micro-holes in the mesh in areas with curvature. Also, some vertices are duplicated and slightly mismatched in coordinates. Please add a more accurate model export. I use a top of the range iPad Pro, a complex heavy mesh won’t be a problem.

It also will be great if you allow us to bind material slots to faces. I find it a bit hard to texturing surfaces in other software in polygonal stage.
