I currently have a texture on a pre-existing model that is 4096 x 4096 pixels. When I export a gltf file this texture is about 28 megs. Pretty big for what I want to do. There's also some other ones. I attempted to resize it by going to Image Editor -> image -> resize
Here I resize it to 1024 x 1024 and hit ok. The image appears smaller on the image editor and the size says 1024 x 1024. However when I save this or export it then it reverts back to the original image size of 4096. Is there something I'm doing wrong? Or another step I need to reduce these images sizes?
