That definitely makes sense to me! Thanks for the info Micky, so as I understood it it's like a combination of what makes this Blue paint look like actually paint on a metal and also helping in dynamask editor to tweak the mask by it's texture. Thanks!!!
Sorry for may be stupid questions. But here's what I can't understand yet: 1. Speaking of attached pic example, the very first layer is blue "Paint", ok.. if it's paint.. why it has "Grainy metal" material in it's first (material) slot? Isn't it supposed to be the Paint only cos we won't actually see any metal beneath it…
