What's New? Houdini 20.5 release notes

History of Major Version Changes
  • 20.5 Karma XPU more stable, MPM (material point method) solver, recipes, car rig, APEX, wrinkle solver, clip with noise/fill, Copernicus and stamp points
  • 20.0 Karma appeared in H18 but Karma XPU was beta; Crowds with MotionPaths (SOPs only)
  • 19.5 Removal of the copy stamp node from the tab menu; SOP level fluids; Redshift standard material in RS Builder rather than RS material
  • 19.0 Vellum fluids

Trend toward SOP level dynamics — to give more options for Houdini core users and convenience for quick FX.

  • 17 Vellum solver (including SOP context); Position Based Dynamics; no more file node in geo container by default; playback controls on left not right
  • 16 What's New in Houdini 16
Please note — the mantra surface shader is still available in H16+, just not in the material palette (forum post). Old copy node = copy stamp node. mat is now the shop interface for the material palette shaders, where you can tab-create a "classic shader" (previously mantra surface shader). There is a checkbox on the shaders to use packed color. RBD static object is now under the collisions tab.
