btw, stupid question - how do I access Point Number ($PT) from VEX code ? I could not find answer in docs.

Currently the only solution I found is by using POP Wrangle and setting @v to v@hitnml there. As Pop wrangle is executed every frame, i'm doing age check - if (@age < 0.05) and setting @v only then. Is there any other solution to make POP Wrangle to set @v only once - when the particle is born?

Hi. I'm still struggling with some basic concepts in Houdini.
I was playing with POP Collision Detect node and the node adds several collision attributes to particles - like hitnml, hitpos etc. What are my options of accessing and using these attributes? What I would like is to use hitnormal *(hitnml) attribute in POP Replicate to set initial velocity for new particles. Is this even possible?
Thanks

Thanks!! Seems like particles always have default @life attribute even if it is not inherited (Copied by Point Generate node deeper in the network). Therefore the setup_life node is not correct.

Hello everyone. I am a newcomer to Houdini and as a programmer in my heart, I fell in love with Houdini immediately!
I am trying to do some particle simulations.
I have a POP replicate node to create trails for my primary particles. I don't want to inherit any attributes, but I cannot get new particle life to work. It just ignores any life expectancy parameters I have set and always uses 100.0. If i turn on inheritance, then it inherits parent particle life as expected.
Is this a bug?
As an additional question - how do I modify particle life later in my network?
Thanks!
