`Alpha Puli` is a one gizmo solution to make sure the alpha you generated works well with the image using all the setups I could find to check if the alpha channel fits.
This node must NOT be used in your script in a way that it would affect the outcome.
It`s main purpose to check your work!
Let`s see how you can use it:
CHECKER / Mode / Overlay
With the `Overlay` selected you have different colors you can choose from that fills your alpha.
