However, i cannot get these images to look right when scaled.
If i make a 64x64 image and then resize it to 256x256, it will look terrible because of the sampling (that's what causes this, right?) - the image is smoothed, resulting in a blurry mess.
While i could make the sprites look pixellated in 256x256, this would result in more work to do (finer drawing accuracy needed) and increased file size, which is unacceptable.
I tried disabling sampling in project properties, however there is no option to do so - only linear and point!
Furthermore, i cannot use the "pixellate" effect on the images because i am running the free version (2 effects PER PROJECT).
Is there a way to disable the cursed sampling and get images to scale without them being smoothed?
Example of what happens:
Apparently what i need is to dispose "interpolation" (a term with which i am unfamiliar with):
