New Curve Deformers

The curve deformers rely on a new Value called MatrixCurve.

A MatrixCurve is a special curve setup with control matrices:

• The position along the curve is given by a piecewise cubic bezier curve built from the control matrices positions and orientations to control the tangents,

• The scale and rotation (around the Y and Z axis) along the curve are given by a cubic interpolation from the control matrices

The curve deformers work as joint deformers and can be mixed together to build a skinning skeleton.

New skeleton modules can be found in the nodes library (most of them remove the need to sample a curve with joints from previous modules):

• CurveModule: a simple MatrixCurve deformer with a set of control matrices

• CurveBendableArmModule: a MatrixCurve version of the BendableArmModule

• CurveFKSpineModule: a MatrixCurve version of the FKSpineModule

• CurveIKSpineModule: a MatrixCurve version of the IKSpineModule

• CurveFacialNurbsModule: a MatrixCurve version of the FacialNurbsModule

New template setup assets can be found in the nodes library:

• template_curve_biped: biped setup using curve deformers for the spine and arms

• template_curve_facial_nurbs: biped + facial rig setup using curve deformers for the spine, arms and facial nurbs

Nodes changes

Private Release date: 2022-09-27

Version 2.0 is in alpha process, and as such we reserve the right to introduce incompatibility with the previous versions, such as deleted Node classes, modified Plug / Node names, different workflow etc…

We tend to stabilisation of the Rig in Rumba, but as of now just consider all the work done with one version to be disposable.

A template setup asset can be found in the nodes library:

• rig_biped-dev: biped setup

Animation and Camera exchange between Rumba and Maya

In order to facilitate the adoption of Rumba in Maya centric pipelines, we have improved different import and export processes between the two software:

Maya camera rigs can now be exported to Rumba as regular assets.

It is now easy to import a Rumba animation project from Maya. Assemble a shot scene in Maya with the characters and cameras references, select a Rumba project and get your animation back in Maya. Great to quickly integrate Rumba in an existing Maya pipeline. When possible, the import process preserves the original animation keyframes.

See Import a Rumba Animation in Maya

It is also possible to export Maya animations in the Rumba’s library animation file format. You can use that to convert an existing Maya animation library or to exchange a camera animation. The export process preserves the animation keyframes.

See Export a Rumba Animation from Maya
