Blend Shapes (aka Morphing) / Maya

Blend Shapes (called Morphing in Verge3D) is a feature which allows you to modify mesh objects in real-time. The most common use case for this feature is facial animation. Morphing also suits well to creating parametric objects which can interactively change their dimensions, shape, thickness, holes, profiles etc.

See the following demo as an example:

Setting Up

In Maya, open the Shape Editor, and setup targets for your objects. Please notice that due to hardware constraints, you can create only one blend shape with a limited amount of active targets. Most of the time it's 5 targets for skinned objects and 6 for others. See this topic for more information about calculating the limit in more complex cases.

During rendering, the engine selects 6 shape targets with largest influences ignoring all excessive targets.

Animating Blend Shapes

Verge3D supports keyframe animation of blend shape weights. Check out the Animation section for more details.

Controlling via Puzzles

To manipulate your morph targets in real-time there are two puzzles: get morph factor and set morph factor.
