Texture Streaming broken with World Origin Rebasing

We found a bug with texture streaming when world origin rebasing is enabled. The engine could not determine the correct mip map level of a texture if the level is large and world origin is shiftet.

I was able to reproduce it in a test project.
To reproduce it you have to package the game as Win64 and start it. You can see the “Unreal Engine” Text in a low resolution. If you open “stat streaming” you can see “Visible Mips” with around 5MB but it should be around 25MB.

I’ve tried it with 4.16.3 too. There the same bug occurs.

Hi,

We also noticed this issue and fixed it few days ago in development branch CL# 3601440. This branch (dev-mobile) should be pushed to Main after 2 weeks, so it will be visible on GitHub after that, and will be part of 4.18.

Thank you very much!

Is this why with my large world the textures are blurring? also cant seem to build grass maps if i add more than 2750 505x505 tiles.
