@DrintThisPotion - Combine the spartial constrain for floor corner - there is an example here a few posts back by Ali that works really well! You can mark all corners and spawn things “near those markers” or spawn void elements near the market making it empty. You can also use the spartial constrain from my answear for pillars corner detection.
[MENTION=28980]Ali Akbar[/MENTION] - How to make a dungeon that is instanced meshes and then spawn powerups that are actors on top of it? not instanced, but use certain rules of the dungeon. I am using the same construction as file land spliting the dungeons. however its still one dungeon on one rule set.
Maybe if its 2 dungeons and one is instanced and one is not? but they use the same random? But Im afraid on the performance to spawn every dungeon twice.
