I'm making a building using 'Building from Patterns' after watching the Titan tutorial in Unreal.
I divided boxes into groups using component tags and combined them with Boolean.
When there is only one pattern, the part combined with Boolean disappears, and walls are not created.
However, if different patterns are given to groups, walls are created even on surfaces that disappeared before, and it can affect other groups as well.
What is a good way to put several patterns in one building?
