RTF Posted June 28, 2021 Author Share Posted June 28, 2021 I tried to generate lines with POP, and then use Vellum to simulate lines. But it can't run. Can someone give some guidance or advice?

vinyvince Posted July 2, 2021 Share Posted July 2, 2021 Vellum runs , it's just you made some mistakes In your vellumhair setup constrain pin i snot set to your pin group . Then you have to polypath to get only one prim. More importantly , the pin change from frame to frame as the sop solver in your popnet add new points every frame... Ok, finally if you drive your contain using the actual transform, you will probably not get close to your reference , play with the scale as well , or maybe restlengh Hope it helps! ________________________________________________________________ Vincent Thomas (VFX and Art since 1998) Senior Env and Lighting artist & Houdini generalist & Creative Concepts http://fr.linkedin.com/in/vincentthomas Quote Link to comment Share on other sites More sharing options...
