UMG Textures extremely pixelated

I have the same issue I have lot’s of icon with many different size that changes with animations and i tried everything for the setup in the details of the texture. But with my 256x256 texture when i try to have on icon 90x90 it becomes very blurry. last post on this topic was 2 years ago. do you have a good solution not involving making a material for each icon now?
