Hi there, I am trying to group particles based on its life attribute. The attibutes value are brtween 0.5 and 3 . I am using a POPGroup Node after the pop source and typing in VEXexpression “@life<2” but it doesnt seem to be working as I expected and also it is not givin me any error.
Have you experienced that before?
Thanks

Are you using:

ingroup = @life < 2;



It works as expected here. Can you provide your project file if doesn't on your side?
