Heya again,

So, I have my particles creeping and moving along a surface using the Creep POP, and that part is working swimmingly. I have an expression/event that tells the particles to cease their creeping and become semi sane particles, which is working, but they tend to want to return to the world position they were in before creeping. I'm using a Location POP to birth them, but was wondering if there was a way to force or “bake” the creeped position into them so when them detach themselves they are in at least close proximity to where they were.

Cheers, Colin.

Well - I was able to get it to work to %80 of what I want to do. I just used the Group SOP and used an expression to create a point group, then emited randomly from said point group in the source POP. It seems to work alright for what I am doing though it's annoying that it's just coming from the points rather than the surface. If anyone has a solution for the surface that would be great. I'm not to keen on the idea of just subdividing.

cheers, Colin

Hi there -

I've been happily whisked back into the world of houdini and familiarizing myself with a lot of the new elements and approaches to things. I'm working on a POP system and I have an input surface with various attributes defined and I want to birth particles off the surface based on the attribute hitting a specific threshold. I was trying the Event POP but that seems to be based on particles “doing things” rather than an input surface. How would I go about birthing particles based on this threshold in a POP?

Cheers, Colin.
