Renderer.GetPropertyBlock - how to get default values?

[eddietree]

I am having trouble just getting default Material values via Renderer.GetPropertyBlock(). I only get ZEROS for all these properties. I got the property names from the debug view of the material.

Is there something I am doing wrong? I have tried this in unity 5.3 and 5.4, both are the same results.

using UnityEngine;
using System.Collections;

public class BugRepro : MonoBehaviour 
{
	void Start () 
    {
        MaterialPropertyBlock block = new MaterialPropertyBlock();

        var renderer = GetComponent<MeshRenderer>();
        renderer.GetPropertyBlock(block);

        // BUG - These values are wrong! Why are they all ZERO?
        print(string.Format("{0}: {1}", "_BumpScale", block.GetFloat("_BumpScale")));
        print(string.Format("{0}: {1}", "_Cutoff", block.GetFloat("_Cutoff")));
        print(string.Format("{0}: {1}", "_Glossiness", block.GetFloat("_Glossiness")));
        print(string.Format("{0}: {1}", "_Metallic", block.GetFloat("_Metallic")));
        print(string.Format("{0}: {1}", "_Parallax", block.GetFloat("_Parallax")));
	}
	
	void Update () 
    {
	}
}

In case you’ve never figured out, MaterialPropertyBlocks aren’t meant to query the properties of a Material. use renderer.sharedmaterial.getColor() instead.
