Sticky Problem

[3__]

having trouble making particles stick to a deforming emitter,

Is there a simple trick to do this?

attached file is for H9.

Did you ever figure out how to resolve this? I'm trying to tackle a similar issue.

yeah PSlow in max, there's a checkbox for it.

I searched through your whole hip file looking for a max checkbox somewhere.

then I realized you must have been talking about Particle flow in 3ds max.

I solved my problem with an answer from another thread using the position and/or collision pop.

However, I can't yet figure out how to animate the influence of the position pop on the particles. I'd like to have it grab them, hold for one or two seconds, then let go.

sorry, bad joke. its a pain in the arse to do it in Houdini,

something about grabbing worldspace uv positions and

setting particle positions to them... for such an often used,

elementary option, i'd rather the check-box.

Actually I thought about it a bit more, and just used a switch pop and property pop to turn the stuck property off and use a different branch of the network at the correct time. It worked like a charm.

I'm trying to solve this myself. Could you post a sample file?

I got particles to stick, somewhat, by using a Ray SOP, but they do tend to jitter around when the surface deforms.

Have you ever tried using the Collide POP?

It makes particles stick and slide on deforming surfaces.

I attached the modified hip file,

tall me what you think
