Hello all
I create a level light it and then create lightmaps. DeleD has created 5 lightmaps in the lightmap folder. Now how do i go about loading the level in my engine???
Does DeleD export lightmap info in x files if not then how do i load them?
Thanks
Mobeen

Well, it all depends on what is your engine ...
It's much more a programming topic for me Wink

.X does not support multi texturing..and therfore does not support lightmaps...

When you export your stuff in Deled to .X it creates 2 meshes with different mapping info; one with the difuse map and another one with the lightmaps. Your engine must be capable of blending these two into 1 single file displaying the lightmap effect. (I think Blitz3d follows this procedure).

The Irrlicht engine uses a different approach; it loads the DMF file directly along with its textures and lightmaps placed in the same folder. The result is the same: A lightmapped level.

So Mappy is right; it's all up to your engine's graphic capabilities.

Hi afecelis,

Could you be more specific? (as I just start learn to use lightmaps)
How could we load it into Blitz3D? Any reference code?

Thanks in advance.

For manually loading a lightmap into Blitz3D :

map=LoadMesh("testmap.b3d")
lmap=LoadTexture("testmap_lm.bmp",16+32)
TextureCoords lmap,1
TextureBlend lmap,2
EntityTexture map,lmap,0,1
EntityFX map,1

But you usually won't have to use this code, because as far as I know, lightmap usually loads itself with the map (level).
Now this code can be handy if, for example, you want to toggle day/night lightmaps for your level ...
