Help understanding texture sizes

Development Getting Started & Setup

Trying to understand how I might be able to reduce my texture sizes further.
I have reduced my textures to 256x256 and it shows a resource size of 43KB.

However if I go to explorer that texture size shows 542KB instead. If I pull up this static mesh and look at the Size Map, it shows me that it is using 554KB for this texture.

My question is if I go back to the texture and I change the max texture size back to 1024x1024 there is no increase in the size it still used 554KB. Apparently changing the textures to 256x256 made no difference, I’m not sure how/why, is there any way for me to reduce this texture size further?

I may have answered my own question above: Appears changing the max texture size right from unreal has no impact, I used a plugin from the marketplace to resize the textures and it had the result I was looking for. @ 256x256 the texture size dropped from 554kb to 78kb, material also dropped slightly in size, but the asset itself remained the same size.

Appears you can change texture size directly in Unreal and it uses whatever the original imported settings were :frowning: The marketplace plugins are easy to use though so not a big deal.
