soft selection

[saca]

hi,
i want to apply any effects into geometry by it"soft selection".
in 3dsMax,  is very popular technique , it's very simply operation.

i had heared, in houdini it's attribute blur.
attribute blur work well on Polygon geometry,
but "polygon-curve" is not soft result.
What should i do?

if you can, please check  my file.

this sample apply ray_sop by "softWeight" attribute.

thanks

Try Soft Transform Sop

thanks,

Can i apply Ray(Sop) and other deformation through SoftTransform(SOP)?

I want any deformation by procedual.

Maybe this Vop Solution Helps ! You need just to Play a little bit with this ... its Sunday can't move fingers

I'm sorry so late.
i had found very nice tutorial about soft-selection.
"HOUDINI FOR THE ARTIST: WORKING WITH THE FALLOFF NODE"
https://lesterbanks.com/2018/11/houdini-new-falloff-node/

H.17 falloff(SOP),
but in H.18, it's distanceAlongGeometry(SOP).
distanceAlongGeometry(SOP) output "dist" atrribute.

showing H.18 version.

Nice @saca and where its your RAY solution or ?

[saca]

Ofcourse, this solution works also on RAY(SOP).

distanceAlongGeometry(Falloff) is similar "soft-selection" in 3dsMax, so procedural for any.

By the way, the first example was to make a curve follow a ray.
It doesn't work well on curves.
An alternative might be to match the curve to the polygon deformation. For example, Lattice Deformation

But anyway, I'm glad that Soft Selection has become easier.
