I have some question about POP, maybe those is silly but always bother me…orz

1. how to spin particle and start as a different direction?
I create a normal different each particle so instance has a unique direction at first. but the POP torque will reset the direction to default. even I use expression give torque a rand axis those particle still start a same direction.
I don't know if there is other way to spin without torque.

2. can POP instance to use multiple source?

3. can POP instance use a animate obj? (animate time need use particle age)

4. use RBD or static obj to do collision (object has deforming) is very heavy, if we have a batter way,please?

well… POP is really difficult for me : )
thanks for help

OK, I solved the first & second problem after I took a great sleeping : )
I give each particle a different instancepath so they will get different sop node. and give instancepath a animate value than the No.3 Q will solve,too. I guess.
but I'm confuse that is a good idea? this idea need too much sop node just like maya, I not really like it…

btw, about spin issue, I give it a orient value directly instead of use torque dop.
