change lightmaps at run time?
I know there has been several posts, but I still can't get the lightmaps immediately displayed on the screen. I use only one lightmap at one time, and the lightmap is updated and stored in the same name. I attach this script to the object which I baked the lightmaps to. Thanks very much!
public class RoomLightmap : MonoBehaviour {
private LightmapData[] lightmapdata = new LightmapData[1];
// Use this for initialization
void Start () {
}
// Update is called once per frame
void Update () {
lightmapdata[0] = new LightmapData();
lightmapdata[0].lightmapFar = Resources.Load("Final_LightmapFar", typeof(Texture2D)) as Texture2D;
LightmapSettings.lightmaps = lightmapdata;
renderer.lightmapIndex = 0;
renderer.enabled = true;
}
}
if your projet is in text mode ( Edit/Project Settings/Editor) can you say me what is the value of lightmapIndex in your RoomLightmap prefab ?
It must look like that in the file :
Renderer:
m_ObjectHideFlags: 1
m_PrefabParentObject: {fileID: 0}
m_PrefabInternal: {fileID: 100100000}
m_GameObject: {fileID: 100000}
m_Enabled: 1
m_CastShadows: 1
m_ReceiveShadows: 1
m_LightmapIndex: 255
m_LightmapTilingOffset: {x: 1, y: 1, z: 0, w: 0}
m_$$anonymous$$aterials:
- {fileID: 10302, guid: 0000000000000000e000000000000000, type: 0}
m_SubsetIndices:
m_StaticBatchRoot: {fileID: 0}
m_UseLightProbes: 0
m_LightProbeAnchor: {fileID: 0}
m_ScaleInLightmap: 1
--- !u!33 &3300000
If the index is not set to 0 I don't think if you do this :
renderer.lightmapIndex = 0;
can work.
Hi liszto,
Thanks very much for replying. I tried to remove the renderer.lightmapIndex = 0; and it didn't work too. Is that because if I overwrite the lightmap in the same name and load it, Unity does not work?
Actually I tried to name the lightmaps in different name, then it showed lightmap immediately, but seems that the lightmap is loaded as "Texture". So now the problem is that I don't know how to change the texture type of the lightmap to "Lightmap" at runtime. Do you have any idea? Thanks!
You can look this Unity Answer topic, maybe this can help you ?
