How to change color to every specific material in a child of a group..?

I got this code from somewhere else.

foreach(Renderer r in target.parent.GetComponentsInChildren()) {
    	foreach(Material M in r.materials) {
    	M.color = setColor;
    	}
}

How do I make it so it only changes color to a certain material?

The material name is “Primary Color”, How do I refer to them…?
can I use string? or should I use an Index?.

If your script is on a gameobject, you could just make a material property and drag in the material reference in the inspector and then check in your loop if the material in the renderer is the same material.

Example:

public Material material;

public void YourFunction() {
    foreach(Renderer r in target.parent.GetComponentsInChildren()) {
            foreach(Material M in r.materials) {
                if(M == material) {
                    M.color = setColor;
                }
            }
    }
}

Edit: Actually, if they use the same material, you only need to change the color of the reference:

public Material material;

public void YourFunction() {
    material.color = setColor;
}

Now, if they don’t use the exact same material and rather its own material instance based on the same material; then I would check for the name of the material instead.

The first method and the second did not work. Actually, the material are instanced, since Every player would have a different coloring. (Object group of my tank for example, which uses multiple material, and each player will have different team coloring.) How do I check for the name? Wouldn't doing that will also change other player's instance since their name is "MaterialX (Instance)" too?.

Well, you specify to only change color of materials of the target, so as long as the target variable is only one player, you only change color of that player. foreach(Renderer r in target.parent.GetComponentsInChildren() { foreach(Material M in r.materials) { if(M.name == nameToCheck) { M.color = setColor; } } }

It works now!, Using the string comparison. I need to add material.name + " (Instance)" to get the stuff working :D Thank you! May you be blessed good sir~!
