i am facing a trouble to make an animated object path trace. actually i want to make a motion trail. So, i need a trace motion path as spline.

try trail sop

Do you mean like this?

thanks for replying, actually i was trying trail SOP, but it was giving me object replication through the path. but i need a curve which i can use with sweep and skin path as a tube. also i want to control it with carve.

thanks again for replying.

yes use scatter on your geometry and then keep only points you need and in method choose appropriate skinning method
check this tutorial it is great for this

this vimeo tutorial link is very helpful to me. thanks.

you are welcome
check also the rest of p quint stuff it is great way to learn houdini
and for all he has also files to dive in and take apart

i have got object motion path, now able to skin it, but facing different kind of problem. i can't control over motion path. it is overlapping another geometry.

please if possible show me a way to control it. i am posting an image and project file.

thanks
