I get a flip problem, it was a simple effect such as fountain.
I built a flip with two particle source include, one is a default flat flip with no velocity.
and another one was emit form object with a upward velocity, it was under the first one surface, so when it emit particle, it will push the first flip particle into air, like a fountain.
Anyway it works a few time at begain, but after a while, the particle looks lost the velocity, it stop push the flip upward, or push a little.
I think it may be the reseed particle problem ,when the particle per voxel big the value ,it will delete the particle. but is was not working when turn reseed off or increase the per voxel value .
For some reason i don't want use pump velocity or particle velocity replace.
Is it something wrong with my setting.
Any help will be great.
Thanks!
