Why are my Bad-Guys spawning inside walls

Development Programming & Scripting Blueprint

I am using a trigger box Blueprint that is acting as a spawner.
My test arena is square and has walls around it and inside of this square with big fat posts all over for “cover”.

The spawner box is spread over the whole lower area of the map. Why is the spawning mechanic not realizing that there is a BSP block there? The inside of those brushes are “Spawnable areas” and I can even fire shots inside of them to kill them.

That is kind of ruining the game…I have tried all sort of collision solutions for this and nothing is stopping that from happening. Please don’t tell me I have to make my spawnboxes not overlap with geometry! Making a ton of spearate little boxes would completely ruin the mehcanics of this.

Hi SoUlFaThEr,

BSPs are hollow and as such objects can be spawned in them. The best thing to do to prevent this is to add a blocking volume within the bsp so that nothing can be spawned internally.

That sounds like double the work for no understandable reason, but thanks for the answer.
