I made aan image with text and drawsdrawings to simulate play pause and that things aboutother audio, buttons and made it black for using it like a maskmask; where one material show troughis shown through the image and other material from everything else but. However, it only shows one material and even using it like a normal image texture troughthrough the diffuse or something isn't working itand doesn't shows, ishow. I made it beforbefore with other renders and never had this problemaproblem if it is important i'mI'm using blender 2.79
