Hello,
i came across 2 issues when i tried to change particle-groups by their birthID with "custom properties" operator.
The BirthID of the first born particle in an event is always 0. But Simulation Groups start at 1. Is there a way to offset that without script?
Also, in "display data" operator, i can not input 0 in the "specifc particle ID" field. Maybe that is a bug?
Further the BirthIDs are also the expected float values: e.g. birthID 4 = float value 4 and so on. so thats fine.
My second problem then is: even if i ignore the first particle, the float value is not really corresponding to the groups.
At least the order is a bit counterintuitive to me.
With float value 3 i get them assigned to sim group "1, 2" instead of just "3".
If i want them to go to group 3 i need float value 4.
float value 5 puts the particle to group "1, 3" (picture) and so on.
Is there some logic behind this order?
Is that just the way it is, or am i doing somthing wrong?
Thanks you!
