When packaging does UE4 keep my imported 4k textures if I set them to 2k?

Guys, as you know, we can set the size of textures without leaving UE4, by using the UE4 texture viewer and set under Compression>>Maximum Texture Size.

With that said, here’s my question.
Say I have a landscape and I import 4k textures for it, but then I decide 2k is enough and I set it to 2k in "Maximum Texture Size’’. What happens to the 4k original size when the game is packaged?
Does UE4 keep the 4k in the package or does it discard it keeping only the 2k?

I ask this because I like to import big images and then reduce inside UE4, but if UE4 keeps the originals, I may end up with a too big file and I don’t want that.

I think it probably keeps the originals. If you want to be sure, best to change them to 2K.

You are looking for this:
https://docs.unrealengine.com/en-US/…ies/index.html [TABLE]

		**Maximum Texture Size**
		The maximum resolution for generated textures. A value of 0 means the maximum size for the format on each ***platform***, except HDR long/lat cubemaps, which default to a resolution of 512.

In other words, yes, you can work with hi res textures and down scale per platform. You can also compare the build file size with different texture sizes to see the differences.

The engine will down scale your texture from 2k to 4k, but the original 4k is still there in the engine.

Thank you guys for the information! It’s clearer now.
