Change a material color

[kmccmk9]

Hello, I’m trying to find a specific material on an object and its children and alter its colors based off of sliders. This is the code I have so far but it doesn’t work. Thank you for your help.

public void ChangeColor(float rvalue, float gvalue, float bvalue) 
{ 
    //Color materialcolor = new Color(rvalue,gvalue,bvalue,1); 
    materialcolor.r = rvalue; 
    materialcolor.g = gvalue; 
    materialcolor.b = bvalue; 
    foreach(Renderer part in r) 
    { 
        allmaterials = part.renderer.sharedMaterials;
        //materiallength = Renderer.sharedMaterials.Length;
        //allmaterials.Length; 
        materiallength = part.renderer.sharedMaterials.Length; 
        for (int i = 0; i < materiallength; i++) 
        {
            if (allmaterials*.ToString() == "malenude-skin")* 

{
allmaterials*.color = materialcolor;*
}
}
}
}

First, from the doc :

“It is not recommended to modify materials returned by sharedMaterial. If you want to modify the material of a renderer use material instead.”

Second, part.renderer is unnecessary, like part.renderer.renderer. It’s correct, but it requires one more GetComponent. Just use part.

Third, the override ToString() of Material inherit from UnityEngine.Object and will give you the name of the GameObject, I’m not sure that’s what you want. HasProperty might more appropriate.

Finally, check how r is created. Maybe it’s just initialized.
