How to implement radiosity effects in game? [ANSWERED]

I am trying to create an architectural walkthrough, similar to the walkthrough standalone demo that is up on blender’s main site (more specifically here). I am using blender publisher 2.25 and I have also lighted a simple room by using radiosity (I assume the same blender version and method was used for the walkthrough demo).

The thing that I am trying to understand is:

What was the method used to get all those radiosity lighting effects to translate into the game engine, as in the walkthrough demo?

If you could please tell me how this is done, or (even better) point me to a decent tutorial on this, I would really appreciate it.

Thank you.

after doing the radiosity calc hit the “add new” button

[that is, by doing the radio calc by hitting collect meshes then GO in the radio buttons]

the new meshes have vertex colors, if you enter face select mode they will show up just like you saw in the game engine.

Social, I’m doing the same thing, and am also searching for a tutorial. Nothing found yet that directly addresses your question.

Here’s a good starting point:

I searched on this page for “Radiosity” and found four links (although the last one is dead):

Question to anyone: Is this last one available somewhere else?

If I make some progress, I’ll post it to this thread.


Thank you z3r0 d, that works, but when I start the game these ugly white lines show up everywhere. Do you know what I am talking about?

Is there a way to fix that?

okchoir: thanks for the tut links.


did you try moving your original meshes to another layer that you don’t set as visible?

This is what I mean:

I have no idea what could be causing this. As for the moving my meshes to a non visible layer; I dont know how that will allow me to see any results in game, since the layer wont be visible. If you could please elaborate on what you meant by that.

Either way I will settle for anything that will get rid of those lines in game.
So, any suggestions you could give me, would be great.

I stick with my previous response

add new meshes adds new meshes

move your original ones to a layer you don’t have visible

when the game engine starts the original meshes are still visible, are turned white, and your graphics card can’t tell which is closer so you see them both [but at different places]

Yes, that was it. As ussual you were right z3r0 d.

Thank you.

That occurs when you have to meshes (faces) on the same place or very near.
