Custom Material is not Updating till looking away?

I have a simple setup where I wanted to have cones with an offset time being scaled, the problem is only one of the materials are updating?

If you look away and look back then the others update but freeze as soon as you look at them again.
Something seems up with this?

What you will see is one cone scaling up on a loop. Then look away for a bit and come back to that cone you will see the others finally updated.

You should set the time value on the effect in the material.onBindObservable observable. Calling material.getEffect() outside of it may have undefined behavior:

Cool thank you, now to make this all a single mesh and material!

Appreciate your help.
