When I was working in Unity there was “Max size” option for texture import (like 256, 512, 1024…) but I can’t see it in UE4, how can I set it?
Open the texture in the engine, and check out the details panel. At the bottom of the compression section, there should be a tiny arrow to expand the section. Once opened you can see the advanced compression options, including maximum texture size. Note that these options will only be available if your vertical and horizontal dimensions are both powers of two.
Are there ways to select multiple textures / folders and set their max size instead of manually selecting each and every texture one by one ? (I have 400+ textures I’d like to set max size )
Thanks
Hey did you find a solution for that ?
Unfortunately, no 
Select all textures you want to change, then right-click and choose “Bulk edit via property matrix”. You should be able to edit Max size for all of them at once.

Hi, maybe a bit late to be useful but I just came across this post. The easiest way to scale a set of textures is to do so using the texture group, you can set max texture sizes, scaling options, etc globally by group in a .ini file https://docs.unrealengine.com/5.0/en-US/setting-up-device-profiles-in-unreal-engine/
