Where to Apply Spring Effect

In iClone, only the bones of an object can have spring effects. However, you can merely turn on/off or adjust the spring behaviors that have already been applied to an object. If you want to apply spring effects to a specific bone, then you need to do it in iClone 3DXchange, version 5.4 or above.

Before applying spring effects to bones, you need to know how and which bones are available for you to manually apply spring effects to.

Standard Actors (how)

The Standard actors in iClone contain the Reallusion Standard Bone structure in which all bones from the Hip to Face, Finger and Toe are all occupied, which means that you are not allowed to apply spring effects to them.

However, there are still some bones that can be given spring effects, and they are the Hair, Breast, Abdominal (G3 actors or above) and Hip Cheek (G5 actors or above) bones.

Non-standard Actors (how)

If you have bone-skinned biped models that are created in any external 3D tools such as Maya or 3DS Max, then everything classified as a kernel bones (from Hip to Head, Forearm, and Toe bones) need to be mapped to the standard bone structure in 3DXchange. The excessive or branch bones, which can be mapped as Extended Bones, are able to be given spring effects.

Non-human Actors (how)

Because the non-human actors are freely created bone-skinned models, every bone can be given spring effects except the root and the bones one level under the root.

Props (how)

The props can be bone-skinned props (from external 3D tools) or merged props (from iClone). Each bone in the structure can be given spring effects except the root and the bones one level under the root.
