I have a question like this

as for you question on the bar red/green adjust thing, in stead of making a 2,1 texture you could make it a 10,1. as you bar depletes or whatever , more red pixels appear instead of green.

thank you

I have another question how to make it green at the starting point that is 0, when you hit full power it goes to red that mean max
