I'm starting to unwrap a model in 3ds Max but I am having an issue where it is not letting me select many of the vertices. I am able to select some but it seems completely random. And it appears to mostly want to select vertices on the opposite side of the model. I have looked around online for answers, but no luck. Any…
Max 2017 got selection bug that I noticed as well, sometimes unable to select certain verts/ edges/ faces. You can try to convert to editable mesh then back to editable poly, it'll fix sometimes, but some other time it just simply wont. Rotate viewport from another angle to view your mesh also might help with the selection…
Collapse the stack, enter Edit Poly's vertex subobject mode. Unhide all in the command panel. Try working with Unwrap UVW again afterward. If that doesn't fix it, enter vertex subobject mode again, CTRL+A to select all, then click in the viewport to deselect the verts and enter Unwrap UVW. It's worth a shot if nothing…
