Texture resolution after package

Hi guys

I have a question about texture size in editor and after package. So, lets say I have a big texture imported to unreal 4096x4096 and it has “X” mb size. Now I am changing the LOD Bias to have only 512x512 Max In-Game. The resolution should have “Y” mb size as it is smaller.
My question is: after makeing a package what will Unreal do? Will it only by 512x512 with “Y” size in mb or will it send 4096x4096 with bigger “X” mb and only use smaller resolution?
Should I only import into Unreal the final resolution that will be in game or can I have bigger texture to work with and Unreal will be so smart to lower down the size? :slight_smile:
