Rigid Body

  • Represents the Old Dynamic System
  • https://madmograph.com/page/2/ (Medical Animation)
  • Sample node to sample the sound effector
  • nd you can also cache MoGraph stuff (except MoSpline and PolyFX) with the MoGraph Cache tag
  • Mograph Effectors as Deformers.
  • That blend feature in the cloner.
  • Ha! Finally a useful nugget for the Fracture. Disconnect the faces. And instead of using the split command every time. Just add in the Fracture and in explode and make it editable.

  • fake subsurface effect from tim claphan
  • back lighting fake. subsurface
  • flickering lights on the mograph shade
  • For fabric use very small flexion and high stiffness values
  • Values smaller then 5% will do fine. Also common fabric is rather stiff (will not elongate much when pulled). Using Stiffness values of 100% or above will ensure this.
  • EPS (Epsilon) values determine the area around a surface in which a collssion will be detected. Usualy this should be set to values of 1/10 – 1/100 of the object size.
  • Polygon EPS < Edge EPS < Point eps
  • If the colliding meshes are equaly subdivided you might only need point or edge collission, thus speeding up calculation.
  • Geometry of collision also matters.
  • Dynamics does not dwell well in small scale. So even if it is a plant. Scale it up.
  • The Cloth Dynamics and Rigid Body Do not interact.
  • On the Spline Dynamics, increasing the steps beyond 3 is actually counter productive. I had it at 72! and it was the one causing me all the trouble
  • Iterations equals the number of points in the spline
  • The instance dynamics where you you simulate at low res and change it to high res
  • Softbody> Stiffness 1000 and Elastic Limit 1cm
  • Plastic
  • you need cloth surface to tear
  • dynamic transition/transition time is amazing.
  • another object rigid body in c4d. nice workflow. parang proxy workflow.
  • wind force can affect spline dynamics
  • friction object in Cinema4D is not contact friction.
  • but more like a damping on the overall.
  • gravity object lets you have a specific gravity on some objects. rather than just an every single object.
  • force object in cinema4d actually creates a force in every object and not just an attractor. so if you have only one rigid body object in the scene. nothing happens. If there are two, you can see it being attracted to each other.
  • hair c4d dynamics can have lesser segments for dynamics calculation compared to the actual segments
