footdust rig concept

a while ago i did a setup in houdini for footdust and ground interaktion dust. i’ve created emitter geo from intersection of foot/object with the ground. a simple attribute transfer did the job. the dust direction is control by black cube on left corner.

on my emitter ego, i’ve used a VOP-SOP network to add a velocity and noise to extra randomness into my emission.

later on i wanna use the setup to created footprint on ground. in this case is just added infinite loop to attr transfer setup. loading the geo from the previs frame and merge it with the current frame. —> it creates a nice trail. this a good start for my footprint setup, which will do later on.

its pretty simple setup for a interaction dust system, but its fast and flexible. it will work also with nice fluids setups.
