indirect lighting for bge, I don’t know if this can be done, But i want a indirect render into a texture to were i can play in!!!
Well… No, indirect lighting isn’t really possible… I would imagine if you set it up so that indirect lighting works in a render, then rendering the scene to texture (baking the texture) would do the trick, but it wouldn’t move with the object. You should ask martinsh; it may be possible with a GLSL shader, but I don’t think so under normal conditions (you could just use a lot of lamps, but that’s very expensive).
martinsh made a demo of colour bleeding which looked sort of similar to in direct lighting but it’s not exactly what your looking for… hell even blender’s render engine can’t do indirect lighting without an external renderer lol so I think you out of luck there buddy.
but if you really want it you could fake it with point lights…
thanks in other versons i could use radiosity but when they took it out i don’t know what to do now!
I think that’s the same as baking the shadows and ambient occlusion maps to a texture to display, so that would explain why they took that out… Maybe I’m wrong.
Blender had a less than adequate radiosity implementation to start with anyway (not to mention it would wreck the geometry used in the calculations as it involved subdividing patches of geometry to get a detailed GI)
It’s been replaced with approximate GI in Blender 2.5 (a raytraced option will arrive when the render25 branch is merged in), it should be much better than the old radiosity method.
Here’s a quick youtube tutorial I used for my 2.5 Indirect Lighting renders.
You may use it for backing.
