How do I properly use the MIX NODE?
Posted: Fri Sep 11, 2020 10:37 pm
Hello. 
I have a 4 color .png image with transparent background, I want to use it as a logo for a bottle, the bottle and its fluid inside have normals pointing outward. I have tried to connect the image in either first or second slot of the material slot in the mix shader node, In the "default channel" of the image texture node it gives me this result: (pic.1) if I choose "alpha channel" I will get this result: (pic. 2) The Mix Factor in the mix node just makes the bottle darker for positive or transparent in color if negative, if I connect the mate material to the slot #1 in the Mix node the results are inverted, dark color in negative values transparent in positive values: (pic. 3) In the Default Channel the image has an unwanted white rectangle on top of the red banner, the original image does not have that as you can see in the pic. 3 (even though it's just a silhouette)
So, how does one use this node to have the result I want?
I am using Ubuntu-Studio 20.04, AMD hardware with 20.30 drivers. Blender 2.83.4 and Luxcore 2.4
