Adding Spring Effects to Props

By adding spring effects to specific parts of a prop, the resulting bouncing effects result in a more dynamic and realistic animation. This pipeline is suitable for any bone-skinned model from other 3D tools or merged models constructed in iClone.

* You are allowed to turn off the spring effect of a bone string for key-frame editing.

** Bone-skinned props can only be created via 3rd-party 3D tools, not in Character Creator.

Adding Spring Effects

1. Load a model with a bone-skinned structure in iProp or FBX formats. The following model comes from the Wild Animal Content Pack by Reallusion.
   
   Note:

   If the prop is constructed with multiple props in iClone, then please merge the props before you load it to Character Creator.
