Thank you

using UnityEngine;
using System.Collections;

public class EmissiveColorSet : MonoBehaviour {
	public Color _color;
	public Material mat;


	void Start() {
	}
	void Update()
	{
		mat.SetColor("_EmissionColor", _color);

	}
}

It is not the color I wish to change, but value on the box into the red circle I made. The multiplier?

I tried something like this:

render.material.EnableKeyword("_EMISSION");
DynamicGI.SetEmissive(render, new Color(1f, 0.0f, 0.0f, 1.0f) * 10);
render.UpdateGIMaterials();
DynamicGI.UpdateEnvironment();

But I didnt succeed to scale the emissive dynamically during game.

I wonder if there is some pre requisite on the material to activate, or in the environment?
