Selecting shape key and applying it on envelopes distorts the envelope

Article needs peer review

Symptom When you select key shape/s for an enveloped geometry using Deform>Shape>Select shape key and then you instance the new shape/s on a shape track in the mixer, you will notice that the geometry is distorted as soon as the timeline hits the instanced shape clip. This is especially true if the envelope has been deformed by an animated skeleton.

Cause

The position of enveloped geometry is not consistent with the that of applied shapes and thus the applied shapes are not resolved properly.

Solution

Mute the envelope operator before you pick the new shapes by Select Shape Key :

1. Select the envelope and open up the explorer, expand the geometry node for the Envelope operator. Open the property page and Mute it.
2. With the muted Envelope still selected Deform>Shape>Select shape key and pick the new shapes.
3. Now unmute the the envelope operator.
4. Apply the new shapes at will and you will notice that the new shapes are applied properly.
