I need to change the lightmap of an object from javascript by specifying the new lightmaps file name. I found a post which had a link to an example but the page could not be displayed.

Shawn,

Could you point me to the post and maybe I can figure out where the example is on our servers.

Here is a link to the old post...

Old Post

Shawn, you would do this in much the same way as you are trying to do in the other post with diffuse texture:

function myFunc(){
vmp.SetProperty('MTSTimeElem.myLoaderElem','Path','mylightmap.jpg','mts_str');
vmp.SetProperty('MTSScene','nerd',1,'mts_int');
}

Whenever you do something to swap textures in the scene from javascript, it is sometimes necessary to re-render the scene to see the change. Just a note on what the last line is for.

I am trying to get this working but it is not updating the light map here is my code


<MTSInstance Name="truck_bottom" >
<Transform>
<Scale x="0.0024" y="0.0024" z="0.0019" />
<Rotate x="0" y="0" z="90" />
<Position x="0.0276" y="-0.0943" z="0.0117" />
</Transform>
<MTSGeometry Name="truck_bottom_GEOM" BackFaceDir="-1" />
<MTSMaterial Name="truck_material" ID="0">
<MTSTextureMap Type="Light" Name="truck_texture"/>
</MTSMaterial>
</MTSInstance>



<MTSTimeElem Type="MTSImageStream" Path="resources/lightmaps/chrome05.jpg" Name="truck_texture_control" Comp="0">
<Target Name="MTSTexture.truck_texture" />
</MTSTimeElem>

Shawn,

This is working. See if it helps you out.
