Use a dops field in point cloud with flip?

[Skybar]

I have a field in dops which is creating an attribute on some flip particles. That all works fine and dandy, however I want that attribute to be spread across adjacent particles - but only within a set radius with falloff. I tried with a point cloud setup, and it basically spread across all of the particles until there were none left unaffected.

I then realized I probably did it wrong, I need to include the field in the setup somehow. So to spread from field -> flip, rather than flip -> flip which was what I did.

I don't really know how to do that though, even normal point clouds is still a bit of a grey area for me. Is it possible? Does anyone have any ideas to set me off in the right direction?

you can blur or feather a field before transferring the data to particles to achieve radial falloff in certain distance

You could also, still using the point cloud method, measure the distance of the affected particle to the source particle and fit that to a ramp in order to multiply the effect. That way you'd be creating a sort of falloff.

Ah why didn't I think of that, both blurring it a bit and sticking a ramp in the vopsop seems to work great. Thank you!

One more question though, right now I am applying this through a SOP Solver with a VOPSOP; is it possible to do it only with a Geometry VOP DOP? I can't figure out what to write to bring in the Geometry to the Point Cloud Open. In the VOPSOP for example I just plug the geo into the first input and write op:`opinputpath(".",0)` (in the textfield for the promoted paramater Point Cloud Texture).
