I have a particle system on an object, how can I animate the scale of the particles so they change size as the animation progresses?
I ask this actually because I seem to have found out how to do this by accident and I can't fix it. Either its a bug or I've configured something wrong, the particles are trees on a landscape and as my animation progresses, the trees spontaneously change size. I did noticed that when the size changes, sometimes i even see motion blur which makes me think its more likely a setting I set while trying to create randomness not knowing it would have this effect?
