RedbeansandRice Posted January 13, 2021 Share Posted January 13, 2021 Hey all! I was hoping to get some help figuring out a way to update the stiffness value of a vellum constraint geometry across the frames of its simulation. I can write an attribute wrangle like the one pictured and it will update the starting frame and the simulation bakes from there and plays as though the values werent changing at all, much less becoming negative. I tried dropping into the vellum solver and seeing if I could figure out anything in there but nothing seemed to work. Im still pretty new to houdini so I expect it to take some time but I was hoping to eventually take whats done in these two awesome videos and merge them into a project where a genetic algorithm produces tensegrities that update their stiffness over simulated time in order to deform in ways that cause them to (hopefully) roll towards a target. Hip file of the simplest version of the problem is attached in case it helps! Thanks for reading!!! VellumConstraintsHelp.hipnc Quote Link to comment Share on other sites More sharing options...
