My problem is that Moho doesn't know how to tell which shape should be in front of another. I've tried using just the layer order. I've tried using "Sort by True Distance" in the Project Properties. But Moho keeps getting tripped up.
See for yourself:



As you can see the red wall keeps getting confused with the floor & ceiling. Also the ladder rails I set up keep vanishing behind the tan wall.
What am I doing wrong?
Or is this just a bug with Moho?
