View Full Version : Constrain particles to surface

10-10-2006, 09:05 AM
Hi Guys,
Hopefully an easy one but I searched the threads with no luck.

I'm animating a fairlground, and I want to have some simple people (just the merest suggestions, like a watercolour painting as the camera will be moving very quickly) on the ground.

So I have my person mesh, a wind force with turbulence at 1.2 and speed at 0.
The Pflow is set up like this:

Shape Instance (person)
Position Object (Ground plane)
Speed By Surface (Ground Plane, parallel)
Force (Wind)
Send Out

Script Operator (on Proceed pCont do ... pCont.particlePosition *= [1,1,0]

However, it's not really going as I planned. The particles still end up moving vertically, and not sticking to teh ground plane.

Suggestions would be most welcome,
Thank you,

OK, I used a drag spacewarp in the end, but it would be great to know how to actually constrain the particles to the (possibly uneven) surface and allow them to mill around.

Lock/Bond operator from Particle Flow Tools: Box#1.

Why don't you give it a visit to Allan Mckay (www.allanmckay.com (http://www.allanmckay.com)) and particlefx.com tutorials, those are really awesome and maybe got the one that you need it :thumbsup:
