How to accumulate points/prims in groups?

[magneto]

Hi,

 

I create a point group but want to preserve the group just like in POPs where they accumulate onto the previous group elements. Is this possible?

 

I use Solver SOP but it feels like it's not really working.

 

 

Thanks.

while this is more straightforward with attributes, it's quite easy to accumulate group using Solver SOP

i am trying to do the same but have the new prims added to a group of their own to track their birth and age.

the purpose of this is to isolate every frame only the primitives that have just been added to the group and do something like subdivide them only when they are born and track their age
