CS0619 'DynamicGI.UpdateMaterials(Renderer)' is obsolete

using System.Collections; using System.Collections.Generic; using UnityEngine;

public class AnimatedMaterial : MonoBehaviour {

private Renderer rend;
private Material mat;
private Color startEmissionColor;

[SerializeField]
private float offsetSpeed = 0.02f;

[SerializeField]
private float glowSpeed = 0.2f;

// Use this for initialization
void Start() {

    // Get the renderer and the material
    rend = GetComponent<Renderer>();
    mat = rend.material;

    // Get the intial emission color
    startEmissionColor = mat.GetColor("_EmissionColor");
}

// Update is called once per frame
void Update () {

    float offset = Time.time * offsetSpeed;
    mat.SetTextureOffset("_MainTex", new Vector2(0, offset));

    float glow = Mathf.PingPong(Time.time * glowSpeed, 1f);
    mat.SetColor ("_EmissionColor", startEmissionColor);

    DynamicGI.UpdateMaterials(rend);

}

}

Hi Collin,

In the recent version they made Dynamic.GI.UpdateMaterials obsolete. I will post the new method, but I highly recommend you let Unity throw the error, and see if you can figure out the new solution from what it says.

At the end of the Update() function:

// Use our "Renderer" to call its own "UpdateGIMaterials()" method

rend.UpdateGIMaterials();

Basically, they changed the way updates to Global Illumination are performed in this more recent version of Unity. Now it's a method attached to each Renderer component (which we stored in "rend" in our code) instead of the Dynamic.GI class. This is super cool, actually, as it makes coding it a cinch and the code is now portable; you could apply this script to any Renderer as a component and it will correctly update its own GI materials without further changes needed to the code.
