Hello. I have a .png image with 2d-map for my game, which has size 36 MB. When I import this image as a texture, I can see that texture’s resource size parameter equals to 174756 KB ~ 170 MB. How can I compress it?
If you double click on the texture you will open the texture viewer, in here on the bottom right you can change the compression setting.
Be sure the image is a multiple of two. ( 256, 512, 1024, 2048, 4096)

I am facing the same problem. I have an image that is 263KB and in unreal it is 4MB. I tried all the cimpression settings but no luck. Can someone please share something in this.
