Dynamic Lights shining through walls w/o shadows
Hi, I'm planning a sandboxy game where the player can place lots of objects but at some point he will surely run into big performance issues by placing too many dynamic lights.
The easiest solution would be turning off their shadows but if I do that the lights begin to shine through objects. Is there a way to prevent this with like Ambient Occlusion or any other cheaper method?

There are a few ways I see how you can approach this potential issue. You can set the Max draw distance of the light actors. You might want to establish a hard cap on the max number of dynamic shadow casting lights in your game. Also not allowing the user to create extreme light radius distances so you do not have too much dynamic shadowing overlap. Finally, using lighting channels to set objects apart from lights will help with performance as well. I hope these give you an idea of where to start.
