saca 6 Posted December 19, 2020 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 SoftSelection_v001.001.hipnc Share this post Link to post Share on other sites
Librarian 576 Posted December 19, 2020 Try Soft Transform Sop Share this post Link to post Share on other sites
saca 6 Posted December 20, 2020 thanks, Can i apply Ray(Sop) and other deformation through SoftTransform(SOP)? I want any deformation by procedual. Share this post Link to post Share on other sites
Librarian 576 Posted December 20, 2020 Maybe this Vop Solution Helps ! You need just to Play a little bit with this ... its Sunday can't move fingers SOFTG.hipnc Share this post Link to post Share on other sites
saca 6 Posted February 22 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.

Librarian 576 Posted February 22 Nice @saca and where its your RAY solution or ? Share this post Link to post Share on other sites
saca 6 Posted February 22 Ofcourse, this solution works also on RAY(SOP). distanceAlongGeometry(Falloff) is similar "soft-selection" in 3dsMax, so procedural for any. FallOff_SoftSelectionRAY_v001.001OD.hipnc Share this post Link to post Share on other sites
saca 6 Posted February 22 Librarian 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.
