Hey guys. I have to show a wide shot of a guy using a leaf blower to blow away a static pile of paper.
I’m emitting a bunch of instanced paper to create the stack.
The instances is using a random starting point only on the Y axis.
I use animated fields to blow it away.
I have a PP attribute to increase particle scale, to grow the self collision attribute as they move. (it’s based on velocity). So essentially the all start of stacked closely together with no self collision, but as they move they push each other away, creating a nice random feel.
That’s all very easy and working fine.
What I would like to do is to ad a randomPP attribute to all tree axis, based on their velocity (or speed) . Basically, they are in a static position with a random Y rotation, but once they move, they rotate on all three axis. I managed to get as far as using a simple RotationPP*velocity. but the problem is that they all move at the same time in the same direction. This obviously doesn’t look natural. I need them to all move in different random directions.
A second challenge, and I fear this one probably cant be done, is to add animation to each paper based on their velocity. So lets say I have an animated sequence of geo. Can I use a “if , else” statment to trigger the animation if say velocity is grater then 1?
Needless to say I am a beginner, so any help is surely much appreciated.
