Hi! After cloning CustomMaterial through a .clone(), it is not possible to access the standard functions in the clone. Is this a bug, or am I doing it wrong? [https://www.babylonjs-playground.com/#UXCB15#109](https://www.babylonjs-playground.com/#UXCB15#109)

hi

[https://www.babylonjs-playground.com/#UXCB15#111](https://www.babylonjs-playground.com/#UXCB15#111)

i notice when i Clone the CustomMaterial the Uniforms Array not serialized and that is empty  
is that way to make them work on serializehelper method?

line 46-47 ( i recreate uniform again )
