I must have blinked watching the gif. What value do you use to get the Alpha/4 channel?
Did you know you could use Dot with a Vector4 as a channel selector? Really useful when using channel packed textures :)

It's not in the gif, but same as the others. You set the channel you want to 1 and the others to 0. So for Alpha you set the Alpha of the selector to 1 and all others to 0.

This is cool for changing it at runtime, but I prefer to set the Component Mask node as parameter an choose the channel from the Material Instance. Nice to have another resource at hand. Keep it up!

I've done the component mask param method as well. So many ways to skin the cat!

I suppose the difference between this and a mult is that is flattens it into a single float channel (for use in lerps etc).

the Channel Mask Parameter node does in a user friendly way (a list of channels) in a Material Instance
-
The channel mask param gives you user friendly check boxes, but that method results in a boolean, on off behavior. The dot prob method allows you to blend or lerp between channel, as well as some other neat tricks. But ease of use is always important!
