Units not rendered properly
The question is do we have the maximum supported unit sprite sizes documented? It's a matter of how much we can draw (restore background) of the adjacent tiles when unit moves away, before it causes other artifacts.
Do you have 'unit_height' defined in [tilespec]?
README.graphics:
unit_height : unit sprite height if more than 1.5x terrain tile
No mention the limits of this support.
It seems to draw properly if you move away and come back, so a full refresh after the unit moves should fix it.
No. I didn't realize there was an option for that. It fixed the problem. Thanks.
Units that are unusual shapes or sizes leave trails and don't fully show, as seen in the image provided.
