Really Frustrating Bug

Recommended Posts

There is an annoying bug that has been preventing a significant amount of development on my game, mostly because I rely on this asset to easily model basic shapes. What's been going on is that every time I pull two top vertices down from a cube to form a ramp, the two faces to the side become completely black. It's very easy to recreate, and goes like this: (I'm using mac by the way) build a 1x1x1 cube, switch to vertex editing mode, and select two top vertices and pull them down. The two faces to the side should become pitch black. This is also being done using progrids, so it snaps by to the bottom instantly when I drag down. I hope you guys can help me resolve the problem.

Hi Zen! Sorry for the frustration, we could probably show a "warning" for this in the future. What's happening is, you've pushed two verts (top and bottom) into the exact same position, which creates an impossible surface, and can't be rendered properly. If that doesn't make sense- when you pull those top verts down, and they land exactly on the bottom verts, they bottom ones aren't automatically deleted.

Why aren't they auto-deleted? Well, we've generally tried to not "guess" what the user wants, and do hidden, automatic stuff. So, you'll need to merge those overlaid vertices- try using "Collapse" or "Weld" (make sure "Select Hidden" is on when drag-selecting, to get both vertices).

Hope that helps!
