I am a novice trying to learn Unreal. I learned about the texture streaming pool problems from tutorials and as an experiment started to lower the size of the memory allocation. Even if I get down to 1 M I can still play a game, no difference is visible and the scene is fairly large. I get the warning but does not seem to cause any trouble. I set the pool size to 0, then it got very bad but I suppose it may not mean much. How is that possible?
Hi @PeterM9999,
Your texture streaming pool is your available texture size allocation. When you hit your budget, Unreal’s textures have a mipping system to display textures at a lower quality to still be within budget. Unreal will do this naturally and mip textures that are small on screen, but this error message essentially means that this is not enough and it will need to mip textures that are larger on screen to stay in-budget. This error doesn’t necessarily mean that performance will be affected- it means that your visuals will be. If you are seeing any blurry textures while playing, this is the cause.
The reason setting your pool to 0 hurt performance is that this is essentially giving yourself an unlimited texture streaming budget. All of those textures that were over budget and mipped down before are now displaying at full resolution.
If you want to learn more about texture streaming and mipping, here are some great resources:
