Graph Maps 1K, after publish some become 4K

[gelbuilding]

I noticed after publishing in SD the maps from SP are not all the same, some 4K and others 1K.

My graph nodes all show 1K, i dont understand why

I think you are mixing up file size for resolution. Your textures are probably all 1K (ie their resolution is 1024x1024 pixels), but some of them are saved in a color bitmap image (RGBA colors, so 4 channels) and some are save in a greyscale image (so only one channel) which means that the former files are 4 times bigger than the latter even though their resolution is the same.
