I have added the png transparent image with the setting and its not showing transparent black background is seen. I have the base color aluminum and i want to add that logo of png on to it. The image is black letter with transparent background why its showing in white letters and black background. May i know where im going wrong any suggestion or help.
To have a transparent background you need a transparent shader.
To overlay the image on top the color used on a shader
Using the same principle you just need to add the color to the existing underlaying material, using the alpha channel to mix it.
(remember to assign the material to that part of the mesh ).
