Radial Health menu like the Evil Within

I know other similar posts exist but the links seem to be broken. I have a radial health bar that works but I have just 2 questions.

I’ve set the health bar from this material but, I’d like to have one colour for the current health (Red) and one for the Max health (dark grey). Would I have to create a separate Material or can I do it here as well?

Secondly is there a way to set the bar to be like this when player health ==100, ideally the bar will not be full when health is 100 so that the bar grows when health is upgraded

you can see here that my health bar is at 70 but I want the radial to act as if it is set to 100 i.e full health

Resurrecting this post as I still have no idea.

What I’m trying to do is have a default health bar of 100 and every time the player upgrades there health it adds 10 health and grows the bar. I don’t want the bar to be a full circle so the full bar would only equal 150 in total.
