A really-really quick test on lightnings and fire effects. What we have here:
- Lame 640x480 raster background.
- Trees slowly moving using distortion layer (emulates wind, hard to notice).
- Lightnings are implemented using plant layers, big ones are just splines.
- Fire in the end is also a plant layer.
Heck, I already like what you can do with plant layers and distortions. Need to experiment with it a bit more.
