Here is a simple QI class I wrote (not the official one). Include this in your code before your tower of babel export file. Then in your code:             var myShapeKeyGroup = mesh.shapeKeyGroups["ENTIRE_MESH"];             myShapeKeyGroup.shapeKeys["Key 1"].value = .5; to morph your mesh using a shape key you created in Blender.   simple example: http://www.babylonjs-playground.com/#1RH0J8#4 animation examples: http://www.babylonjs-playground.com/
