I've been playing a few games recently, and saw something cool that they started doing that I haven't seen before. Basically, any texture beyond the character's view range looses detail simillar in how LOD works for models, except it does the same for textures, which really saves alot on FPS when there's alot of high resolution images nearby. I've recently had an issue with this because I'm using 2048 images on terrain as well as models, so the FPS drops quite drastically when the player is around areas with these textures.

What I'm trying to find out is if it would be possible to make textures beyond character's view to loose detail, and gain detail once the character enters the viewpoint. If this feature is not yet present in the engine, that I guess it would be a great advantage to add it if possible.

this is already present, along with mesh lod, and shader lod, and skeleton lod
