This thread is probably in the wrong place, and I failed to find one that deals with this exact problem that I’m having but gotta start somewhere :).
This is actually a recurring issue, so I’ll try to describe it as simply as I can.
I made a pillar out of one brush object (box), lets say it has about 6 different splits that were then shaped using the pen tool.
When this pillar is placed against another brush object (box), unmodified, a portion of this object (where the pillar is covering it) becomes invisible; as if that one portion of it had a “deductive” visibility option (or whatever is opposite of additive).
I can’t imagine this issue not been mentioned before, so if anyone can point me in any direction - thank you in advance.
