kleer001 Posted 8 hours ago Share Posted 8 hours ago (edited) Vellum reads SOP point attributes once at sim init, then runs entirely in DOP space with no link back to the source SOP. Animated Cd, animated stiffness masks, time-varying pin weights, all silently dropped from frame 2 onward. The standard fixes (hand-rolled popwrangle microsolver, separate cache + Geometry Wrangle DOP, learning that microsolvers don’t run on the creation frame) are nontrivial plumbing. This HDA is that plumbing in one click. Same popwrangle-in-Pre-Solve pattern SideFX Free download: https://kleer001.github.io/funkworks/vellum_attr_stream Houdini 19.5+, any edition. FX users: a build script is included to compile the HDA clean under your own license. More free tools at https://github.com/kleer001/funkworksuses internally for muscleupdatevellum.
