Hello all DeleDians
I have made a 3d level loader in DirectX. I have made lightmaps in DeleD Lite and now want to incorporate them in the DX app. My questions are
1) I have seen the lightmaps generated in the liightmaps sub folder under textures. How do i apply these to my DX app. DO i have to do multitexturing or what?
2) Can DeleD bake the lightmap in the texture or mesh?
3) How can i view the same view n DX App? The info given in my texture is tiled differently to that given in the lightmap so how can this be done?

Let me know asap.
Thanx in advance

Hello, i'm an OpenGL guy, but basically, the process is the same.
1) You need to use multitexturing, yes. On the first texture unit, you bind the actual texture and on the second the lightmap. But don't ask me how this is beeing handled in dx Wink

2) DeleD can't bake it in the texture and this would be against the philosophy of lightmapping, for you will need an extra texture for each polygon, which will end in an huge size of your texture folder Wink

bake it in the mesh -> i don't know what you mean
3) I'm not sure if i get your question correctly, but the lightmap texture coordinates for each vertex are stored in the lightmap line, see the file format explanation.

I hope I could help you Smile

I do not understand how you can bake an image "in the mesh itself". How does that work?

Inside the .dmf file format, u,v coordinates are provided at the end of each polygon definition. For multi-layer materials, there are multiple sets of coordinates. The lightmap information is always stored in the last layer.

For example, let's take the following polygon definition
