Thanks for the suggestions!!
I actually had two issues.
I must have been 'ing out my texture pool. Calling “ConsoleCommand(TEXT(“r.Streaming.PoolSize = 2000”))” fixed it. Now I’m wondering if this means I need to cut down my texture usage dramatically. (BTW, calling SetQualityLevels will set the PoolSize so you’ll need to override the pool size everytime you change Quality levels)
I also included pictures of starfields that looked terrible. This was actually unrelated to the texture pool. This was autoexposure settings at different Quality levels were giving me dramatically different effects.
