I'm having second thoughts on this. An intensity value of zero is effectively off. Is it possible to use the existing intensity field instead of creating a new field?

This value allows you to turn on and off for a specific value of intensity, otherwise you need to set to zero the intensity and then restore or add a new value to the intensity.

I don't know if this is a good reason to add a new value.

That's a good point. I'm okay with this.
