Skinning (Envelopes)

Yes

 

Shapes

Yes

• Export All and Export Selection modes are supported.

• The Maya Envelope value is a global scaling factor applied to all the weight values in the blend shape deformer and it can be used to increase or decrease the effects of all the targets at the same time. On export, the Envelope value is baked into the weight function curve. If the Envelope value is animated, the weight function curve is plotted along with the baked-in Envelope value animation.

• Support for blend shapes that use targets whose objects exist in the scene as well as targets whose objects have been deleted from the scene.

Bones

No

Converted to nulls.
