flo_NH Posted August 19, 2019 Share Posted August 19, 2019 (edited) Hello everybody, I want to strech and squeeze the points of a geometry based on a texture. The points should only move along the surface of the original geometry. How can I do this? I am not a pro in Houdini yet but I am getting better.... Below is a gif animation of my setup in Cinema 4D, which had too many limitations, so I want to create this in Houdini. My first attempt with the Spring SOP and the "tension" point attribute didn't worked out (see attachment). [Update / Clarification]: I'm looking for basic hints like which node / solver I should use etc.... Many thanks for any help or hints!

flo_NH Posted August 20, 2019 Author Share Posted August 20, 2019 Hey everybody, I just found out that you can't set the tension per point or primitive with Spring SOP see: https://www.sidefx.com/forum/topic/2104/?page=1#post-8680 I tried Cloth as well but I did't found any way to expand or shrink it with point attributes. Basically I want to set a force per point to repeal or attract the other points (but in a cloth or softbody like manner): Do you guys have any hints which solver or method I should use? Thanks a lot!
