nice trick, thank you very much
btw. I used also photoshop and I did made some copies of the (alpha)layers, its bit better, but the colors are not the same, like on the sandbox canvas.
My Image from today, only texture from Vervette, and did very dirt painting in the end with verve ....

Done with Vervette, this Normalmap tool:
