Bex Posted April 20, 2020 Share Posted April 20, 2020 Hi, newbish to Houdini. Stuck on how to apply a vellum animation to another object. I have a mesh that is very high poly with holes, I have taken an earlier version of the mesh before it got detailed and have a basic vellum ballon sim collapsing to the floor. How do I transfer the vellum animation over to the higher detailed model? I thought it would be with pin constraints, forcing the other model to copy the vellum animation, but I can only find information about getting the vellum to follow the other objects animation, not the other way around. Can anyone point me in the direction of what I need? Bex Vellum.hip Quote Link to comment Share on other sites More sharing options...
Noobini Posted April 21, 2020 Share Posted April 21, 2020 haven't looked at file but isn't it just pointdeform ? Quote Link to comment Share on other sites More sharing options...
Noobini Posted April 21, 2020 Share Posted April 21, 2020 (edited) this may sound like i'm whinging...but meh....don't care...just my 2 cents...since you said you're 'newish', i don't get the unnecessary overcomplications in your file: - what with the incredibly highres geo for vellum sim ? - what with all the convoluted vdb setup ? all the complexity for a nonfunctioning file is meaningless. - i would polyreduce the crap out of your geo before feeding to the sim, i used 20% - your vellum settings are all wrong...your stiffness is 10e8 whatever while the Mulipliers are 1, huh? it should be the other way around - once you get vellum settings right, didn't even need pressure - the simplified file now runs in realtime ! - couldn't take anymore of the convoluted vdb stuff so i pointdeform at the 'wire' stage, you sort the rest out. - simple file works...why oooooovercomplicate things ? i just don't get it. vu_Vellum.hipnc Edited April 21, 2020 by Noobini Quote Link to comment Share on other sites More sharing options...

Set myself the goal of learning it during the lockdown, my knowledge is all pieced together at the moment from different tutorials and what I dig out of the help file. The majority of the vellum settings were left at default, I only changed the gravity, added a ground plane and added pressure. It created the effect I was after, I didn't know it could be stripped to less than that. The VDB when smoothed after wire stage creates an organic effect on the mesh, wanted to see if it was possible to animate that organic mesh with a vellum controlling it. Your right, point deform was what I needed, never used it before, thank you for your advice and help. Will look into what else I can trim down in the file.

Bex ok, keep on exploring, experimenting, just my personal pref that if i can do something in a simple way, l'll take that any day...plus the fact that i've only got a dinosaur PC...i'm forced to keep things simple and lean.
