I'm not sure if this is an actual issue, or just what's gonna happen, or what but I've been playing with asteroids, and decided to see what TG can do exporting them, and it actually looks like it's very capable except for one issue. In each instance, even when rotating the planetoid, or making the furthest distance in the micro exporter further away, there is one part of the asteroid that pinches together or stretches. On the initial import this area is black without UV, but a recalculate normal fixes this, as well as all the details on the surface, but the bad geometry remains of course.
Is there anything I can do to fix this, or is this just like a seam issue with warping the planetoid? It doesn't produce a bad spot in TG FYI, just the obj export.
Edit: Forgot an exmaple of the issue
