i have a mocap walk body , create sand or snow or particles inside , only use first frame creation particles and i want this follow the animation , like if mesh is attractor of the particles , kind of input mesh attract of ncloth

Hi marcury,

You can think of an animated object as a collision, and then the particle will follow the object.

yes but i do not want to deal with collision , i would prefer something softer attracting the particles to animation , i wonder if typical mocaps dancing man made of sand , and sand following the dance while some sand falling down , its just making the mesh colliding?

You can compute velocity on the animated mesh, convert to volume and propagate the voxel velocities to a voxel_field. This can be used as influence using influence_set_property node. Gradualy bool away at your animated mesh and use that as an input for mask_influence. This will release the particles.
