i give up - i cant figure out, why it doesnt do anything at all
That's all you need to do. Script named "rotate", is where you copy script from website (
link) (you can call it how you want, rotate, wind, dfgdfg). Then add new script with one line. Both scripts are definition scripts.
Though they are a bit different in what exactly they select and where to apply effect, both versions will work in one scene scenario. Just copy paste any of these in to your second script.
setRotateAnimation(Scenes["001-001_scene"].Objects.tree, 0.9, 5.0, 5.0, 1, graphics.noise)
setRotateAnimation(Objects.tree, 0.9, 5.0, 5.0, 1, graphics.noise)
