Hello guys

I am a newbie of houdini~

I have some question:

1. Hittime
as file popLsys_testH15.hipnc
I use popnet to create a particle emitter and collide behavior,
and i want to use “hittime” to be a parameter in Lsystem Generation
When i press mid-click, i can see the hittime attribute appear in popnet.
BUT
i use attribute create sop to get hittime attribute, I cant use it $HITTIME
so i want to ask about how to get the hittime attribute…??

2.La Luna

I want to create stars like this,
I found a material before and i change something, and I use geolight,
BUT I cant create a effect with light like the pixar La Luna stars.
So the material is in popLsys_testH15.hipnc file

Thanks a lot~~~

ps: the origin material i got in this topic of Technical Discussion Group:
