Texture LOD bias vs resize

Hi, this question has bugged me for a while and I have never been able to find a sure answer on it!

I use LOD bias on textures to scale them down for optimization, however, I have wondered if this is as effective as re-importing the textures at the desired scaled down resolution.

Any info would be awesome :wink:

I believe on package it actually gets scaled down, so the end result is the same in file size/performance. However on play in editor the full texture still gets loaded.

EDIT: found an official answer here: Need confirmation on LOD bias for textures - UE4 AnswerHub

Awesome thanks for digging that one up! :slight_smile: This is good news
