  1. How to constraint fractured geo to animated alembics?

    Thanks for such a quick reply dude! I can't look at it right now, but i'll be doing that first thing tomorrow, and let you know! EDIT: update, it worked enough for what i need! Thanks so much!!!
  2. Hi all, Does anyone have a workflow for attaching fractured geometry of an animated alembic, to the animated alembic itself? For example, a moving vehicle that's animated to collide with something and continue moving (the whole sequence of how the vehicle moves is hand animated), so only some parts are fractured for the rbd simulation (like half of a plane's wing, some window glass, parts of the nose fly off), but the rest of the parts that aren't affected are animated via the alembic to continue moving. I've tried attaching the constraints to the timeshifted alembic geo, then use transform pieces for animating the static objects, but i think my constraints are invulnerable right now? They don't break and no forces can affect them, even if i set my strength values to 1. I wish i could send an example file but i'm troubleshooting for work, so i can't actually do so. Any help or hints would be greatly appreciated, and thank you anyone for taking the time to read.
  3. Vellum string constraint break

    Hi everyone, I'm currently having trouble with breaking a vellum string object in half. The idea is to make a saliva strand that's stretching before breaking in the middle. Currently i have a line that's vellum string, attached at the top point via "pin to target" constraint to an animated object. (string constraints are SOP level, fed to DOP node, with "pin to target" constraint done within the sop solver "forces" subnet) Sim follows the object, and i can break the "pin to target" constraint itself via the vellumconstraintproperty node, set to the group with the top point. I tried various ways to group the centre point of the line, and keyframe another vellumconstraintproperty node, but it doesn't work. Can anyone enlighten me on the proper way to break string constraint points in a keyframe-able way instead of just using stretch stress? Thank you very much in advance!
