yea its a lot of decos. But since the game won't ever add foliage, got to make them myself. As decoration for background or for use on civilian buildings, it isn't a big issue. There's no AI so if you spawn it on player team, things won't shoot at it(with attacking salvage off). So you can use this to make the battlefield more interesting albeit it'll be laggy in any large amounts.

Using the propellers for the leaves is a good idea. It's a lot of decos but it looks nice.
