Hello Houdini Cracks 🙂

I am once again struggling with something that appears seemingly simple from the outside so I wanted to ask for your expertise.

My goal is to create a force field based collider around an object.
Because if I have an actual geometry collider around it and I release it the particles move outside of it very abruptly and I want the dissolving of the collision to happen super smooth and gradual.

But the main problem I run into is that Houdini seems to be very specific about Volumes being hollow. I do not even manage to scatter points only in the band around the hollow part of the sphere. It always scatters them inside the geo as it was filled.

I found this reddit post which is supposingly dealing with a very similar question but has no answer to it.

Any tips on how I could build a forcefield that goes all around an object in a band but that doesn't affect the rest of the interior?

Thanks a lot in advance.

Hi Houdini Wizards.

I am currently testing Houdinis Keyframe Capabilites.

Usually when keyframing animations in Cinema 4D or After Effects I am very used to quickly set in and out points in the timeline to loop certain parts of animations.

For example in After Effects it is "N" and "B" to set In and Out Points to Loop.

I couldn't find similar Hotkeys in the Menu or with Google Searches.

Any hints?

Much appreciated.

Also generel keyframe animation courses are welcome.
