Hue slider help

The color slider by default can only target a single object. To simultaneously change the colors of multiple entities, you will need a custom script. It will be somewhat similar to what I have here, but with some important changes. Here is some sample code. Usually I would use arrays to input multiple images and materials, but Lens Studio wasn't liking that for whatever reason.

// -----JS CODE-----
// @input Component.Image image1
// @input Component.Image image2
// @input Asset.Material mat1
// @input Component.ScriptComponent colorPickerScript

function handleChange(value) {
    print(value);
    script.image1.mainPass.baseColor = value;
    script.image2.mainPass.baseColor = value;
    script.mat1.mainPass.baseColor = value;
}
script.colorPickerScript.api.addCallback('onColorChanged', handleChange);

And here is an example project: https://1drv.ms/u/s!AgrmjXTXUbfzgthXl1_JmVds6NZtTg?e=xQ6G0w

I know the flame outline is some sort of custom material, so to adjust the color for that you may need to change a separate value rather than the baseColor. You can hover your mouse over the color name to get the property. So an arbitrary example you may be setting script.mat1.mainPass.flame1Color = value; instead of script.mat1.mainPass.baseColor.

You'll have to adjust the script inputs so you have the right number of inputs for your lens. When the lens turns on, everything will have their original colors and then once you adjust the slider it will start changing things. You might want to select the color picker script, enable the "Edit Properties" option, and then change the initial value to 1.0 which corresponds to the color white which in turn would make all your starting images/materials not have a tint.

No need for the case statements. It'll just be

script.Hearts.mainPass.baseColor = value;
script.Crown.mainPass.baseColor = value;
script.EyeColor.mainPass.baseColor = value;
script.Flame.mainPass.colorMin = value;
script.Flame.mainPass.colorMax = value;

and remove the following lines

handleChange(script.initialValue);
script.colorPickerScript.api.setSliderValue(script.initialValue);

The initial value portion in my original script was meant for when using the slider as a 0-1 scale. It doesn't directly translate to when you are grabbing the color so I removed it.

Can you share the files with me? My email address is my username at gmail.com. It's probably just a small scripting error.

Glad to hear! Looks like a cool lens!
