I figure out the logic to do it but I am pretty new with using mel script to control nParticle/particle...So I am wondering if anyone can help, so here is my logic:
1)emit first particle and set a lifespanPP=1 (any small numbers)
2)when particle 1 die, record its position x, y,z
3) at the same position, generate particle 2 and 3 (so it will look like one particle come two particles)
then create a loop to make every particle to go through step 1,2,3.
So that my idea about how to create the cell division scene.....is there anyone can help me to convert this idea to mel script? Thanks a lot!
