hi guys and gals:

This demo I have on YouTube is something geared for beginners but experts might find it useful as well.

It is quite easy to animate the Sculpt SOP Brush along the surface of a polygon (maybe NURBS as well?) and all you need to do is check out the link and see it in action. I won't post the file because the node network is so simple and easy to replicate on one's own workstation.

Thanks for checking it out. Hopefully I can come up with more basic and easy things to share in Houdini as I think of them.

above is a link to a part 2 video on this same topic. if you want to sculpt on top of a model other than a box and have the sculpt brush animate, then using the Ray SOP as described in this video is one approach. keep in mind that this technique simulates a Sculpt Brush but is not exactly a Sculpt Brush. while i have used Houdini casually for many years i am not an expert and this is just one technique that came to mind when i thought of trying to solve this problem.

thanks.
