Reading Shader Color

  • Hi, Keong Seet!

    Looks like your material doesn't have a baseColor property.

    Did you create a Node Graph material? Can you check the scripting name of your Color Parameter? 

    If this is the issue you can either change scripting name to baseColor  or access it via: 

    //@input Asset.Material mat
    print(script.mat.mainPass["Tweak_N0"])

    Hope this works!

  • Thanks Olha.

    It looks like the base colour isn’t set when the script runs on initialized. I placed the script on a tap event and it’s returning a ver4 value. But the value seems to be the same no matter what colour I set it.

    Is it not possible to access the updated color from the shader?

  • Thanks Olha for the reply. I see you are using a "Color Parameter" node, I want to read the color from the Shader when its been assigned by something else like a "Color Value" node.

  • Sorry I don't quite understand what are you trying to achieve. Maybe you could provide some context? Value nodes are designed to return predefined value, you can't assign or access them from the script.

    If you want to access a result color of a shader you can render it and then access a pixel color of a Render Target texture using getPixels() method of a ProceduraltextureProvider. Is it something that you might use? example

    Let me know
