I have 2 planes (grass courts), one is small and one is big.
There is a hair particle system on the small one (for example emission number 100).
If I apply the same particle system to the big one, emission number is still 100, but the density will be lower because I apply particle system on bigger area.
My question is, is it possible to automatic change emission number according to the area size? (to have the same density on both planes)
