Didn't know about the transparency taking more memory. Then again maybe it is quite hard to avoid without fine tuning every frame. I mostly thought using this on isometric games and not really much else. I would basically only need it to draw the player from normal map to isometric view so it would be only used for position and animation.
[quote:b811ghtb]But I do see, this can be useful for some background stuff... I just remembered how much I miss "Load image from URL" in Tilemap object :/
I would like that as well.
