• Import an image as a texture, to use as background reference
• Fill the layer with it
• Import a low resolution, symmetrical OBJ
• Move it forward so it doesn’t intersect the reference
• Enter Edit mode
• Turn X Symmetry on
• Turn on perspective
• Select the move brush and try to move some vertices
The symmetry is all out of whack.
In this state, if you turn perspective off the symmetry works, but with perspective on it doesn’t.
This bug seems to be new to ZB4 (I’m on a Mac, if that helps).
