tyActor Helper

The tyActor helper can be used to transfer character rigs into tyFlow for use in crowd simulations, in a way that maintains skinning weights, object hierarchies, and keyframed animation of the input objects.


  • Actor rig objects: All objects added to this list will be added to the actor, and processed by tyFlow.

  • Show icon: controls whether the tyActor icon is displayed in the viewport.

  • Icon size: controls the size of the tyActor icon.

tyActor object properties

  • Open tyActor property window: opens the floating property window for tyActor rig objects. You can use this window to override particle properties of objects (for later use in the corresponding flow). Properties are stored as User defined properties on the affected objects.


  • Animation sequences: a list of sequences added to the tyActor object, for use in the corresponding flow.

  • Sequence name: takes string input for the name of a particular animation sequence being added.

  • Start: the starting frame of the sequence.

  • End: the ending frame of the sequence.

  • Non-skin deformations: controls whether non-skin deformations are to be considered during sequence playback by the corresponding flow (morpher/bend/twist/etc: anything that transforms vertices over time). Turning this on allows users to assign any vertex animation onto the resulting actor particles, not simply skin deformations.


  • Force biped “in place” mode: this is a workaround to solve the problematic “In Place” mode of character studio bipeds, which does not stay enabled in certain circumstances. This setting will force “In Place” mode to be enabled, prior to rig evaluation by tyFlow.
