Hope that helps! Marius: In SmokeBitmapData::update, you could replace the three copyChannel lines by:

fillRect(rect, 0xffffff);
copyChannel(_flowData, _rect, _origin, BitmapDataChannel.BLUE, BitmapDataChannel.ALPHA);

Hope that helps!

It can be made to look different however, by tweaking some settings. Also, the smoke is scaled up in this case, to create larger patches (and improve performance), so scaling it down would probably look better :) Haha you’ve got a point ;) But with smoke, the source doesn’t tend to jump around a lot.

I looked it with FP10. It looks normally with static mouse position, but with moving mouse the smoke has quadratized form )). I sent mail for you with some text. Hi David, your smoke is ugly ))).
