SRT Node Transforms

Yes

 

Advanced SRT Node Transforms

Yes

Support for pivot, neutral pose, etc.

No

 

Deformations

 

Element

Softimage Export vs. Maya Import

Comments

Skinning (Envelopes)

Yes

 

Shapes

Yes

Support for blend shapes only, including weight animation.

Note that the Maya import implementation only supports shape manager style weight animations. In other words, when importing into Maya, Crosswalk looks in the corresponding Mixer for the first instantiated animation clip using the shape key X and applies the weight curve of that clip to the blend shape X in Maya. If you create shape animation in Softimage with a complex Mixer setup where more them one clip with the same shape key as its source are sequenced, mixed, or blended, regardless of this, only the first animation clip’s weight curve will be imported on the blend shape weight parameter in Maya.

Bones

Yes

 

Animation

Constraints

No

Plotted on export using the Animation Resampling options.

IK

No

On export to Maya, the Preserve IK Chains option must be turned off. When this option is off, IK animation is plotted to FK.
