Multiple lightmapping for a scene

Hi,
i need to have a scene with 2 different lightmap (the same scene with and without light) and i need to switch between the lightmaps by c# script.
can anyone help me?

Thanks in advance!

I found a solution by myself, i poste the code, hope that this can help:

using UnityEngine;
using System.Collections;

public class LightmapController : MonoBehaviour {

	LightmapData[] lightmapData;

	void Start (){
		lightmapData = new LightmapData[1];
	}


	void setLightmap (int index){
		lightmapData[0] = new LightmapData();
		lightmapData[0].lightmapFar = Resources.Load( "lightmaps/test/LightmapFar-" + index.ToString(), typeof(Texture2D)) as Texture2D;
		LightmapSettings.lightmaps = lightmapData;
	}

	void Update () {
		if (Input.GetKeyDown("t")) setLightmap(0);
		if (Input.GetKeyDown("o")) setLightmap(1);
	}
	
}

The way I swap light maps is I have a duplicate scene with different light settings, doing this means you only need to swap the images that change.

m_Index = GetComponent<Renderer>().lightmapIndex;
m_OriginalMap = LightmapSettings.lightmaps[m_Index].lightmapFar;

This is how you can get the current light map data for a renderer (for when you want to swap back).

I couldn’t find any nicer way to access the alternate map than dragging it onto the script as a public variable.

The actual swap code is this:

LightmapData[] data = LightmapSettings.lightmaps;
if(m_UsingOriginal)
    data[m_Index].lightmapFar = m_AlternateMap;
else
	data[m_Index].lightmapFar = m_OriginalMap;
m_UsingOriginal = (!m_UsingOriginal);
LightmapSettings.lightmaps = data;

My data only included far lightmaps, if yours had near lightmaps I assume you would swap those in the same way.

I would love for someone to come tell me there is a better way but this is how i did it.

Hope this helps.
