As a developer, it is currently impossible to use square asset images or asset images without a circular mask. If the automatic mask that was applied to assets was removed, it would allow us to create more unique and interesting designs. It might also help to reduce image file sizes since I’m guessing you wouldn’t need to store the alpha data, although I could be wrong.
Obviously removing the mask from all the assets that have already been uploaded would be a bad idea, so it should only apply to newly uploaded images, or alternatively, allow a toggle to let us choose if we would like to use the mask or not.
