    Hello to everyone,
    I have this material in Blender where i have 2 Principled BSDF shaders mixed with mix shader and there is a texture connected to fac of the mix shader.
    I would like to change the Principled BSDF Color.001 – color of the 2nd Principled shader
    according to the Principled BSDF Color. (this color is changed by user)
    Lets say if the RGB value is higher then 128, then it change.
    Or maybe it would be easier just to set colors for which the Principled BSDF Color.001 would be black .
    Could anyone help me with this please ?

    You can’t compare a color in the RGB format with a number. An array of numbers cannot be less or more than one number. Your condition will always return false

    Puzzles and JS. Fast and expensive.

    If you don’t see the meaning in something it primarily means that you just don’t see it but not the absence of meaning at all.

    Compare the red, green or blue channels separately.
    The range for these values is 0-1.
    128 corresponds to 0.5

    Thanks for your help kdv, but I did not have much luck with your setup,
    when i adjust it to this.
    the Principled BSDF.001 Color changes according to the value in the “if part”
    0.08 – is the threshold for some reason ?
    But it does not change regarding to Principled BSDF Color.

    Use this puzzle. See inputs, outputs, condition in the console log.

    Have no idea what are talking about.

    Yes you are right. That was actually the best advice !
    I got it working with the puzzle i posted above just swap the LSB material to the variable i am placing the “variable material”
    I am a bit lost in JS so in the Verge puzzles also, but slowly thanks to Verge i am getting better :-D
