I've came up with a question regarding weight painting and color vertex data. So this is the explanation to my question:
I would like to use the gradient I created as weight paint to create a mask with B&W information and use it in the node editor like when I create a color vertex data and re use it with the atribute COL in the node editor.
I created a mask manually to show what I ideally want.
Is there a way? thanks a lot in advance!
