Question Why doesn't Multiply work to change the texture color in Unlit vs Lit?

    I am brand new to working with Shaders, and haven't worked with any code for them, only the Shader Graph. It's very possible I'm missing an extra necessary step for Unlit that I don't know about. upload_2020-4-26_9-36-49.png upload_2020-4-26_9-37-44.png

    Main Texture -> Sample Texture 2D -> Multiply (by Color) -> Master

    Lit: Note that Preview is displaying the desired outcome.

    Unlit: Note that following the same steps did not produce the desired result.

    Why? Is it me or a bug?

    Me too. The situation is similar for me. I'm work in 2D laser line:
    Sample texture 2D + Color -> multiply = nothing... :S
    Sample texture 2D + Color -> add = work but no glow effect.

    Your color property likely has an alpha of 0. The sprite master nodes use the Alpha value of the color as the alpha of the shader, so just edit your color property to have an Alpha of 1.

    Select your Color(4) Node. The 4 in there stands for RGBA. By selecting it you should get settings for changing the alpha properties.
