Rigging Restrictions

To help Nemo understanding your purpose, rigging may need to do extra work:

• Nemo will "ignore" any features that animators can't directly access to.

  • any attributes locked or not in channel box are ignored by Nemo

  • rotateOrder attributes of FK or IK controllers need to be put into channel box

• For best performance, Nemo won't keep hierarchy of controllers(but hierarchy of mesh left untouched)

  • to keep empty group above controllers, please make sure it has default xform and not driven by any other objects

Incomaptible Rig Settings：

• Cycle Warning

• some syntax of expression is unsupported by now:

  • sequential assignment, like a=b=1

  • read value from outputs (like they're inputs)

  • use maya commands like getAttr or else

• scale contains zero

  it's acceptable if it's very small, like 1E-5

Some features may affect result:

• closestPointOnSurface may have very different U or V result from Maya at pole points, because U or V has no effect on position at pole points.

• closestPointOnMesh may have different face id from Maya if the closest point happens to be on the edge.

• transferAttriutes is unstable is projection are close to geometry border.

• Result may be different when converting between euler angles and quaternions. That's beacuse there're two opposite-sign quaternions, and many more euler angles, to a same rotation.

• IK

  • preferredAngle may cause offset.

• noise is unable to exactly reproduced.

  • ramp node also used noise.

• Geometry may get broken if there're zero dividing case.
