Thanks

Can you somehow show where the light center is? E.g. put a light entity there.
Can you extend the cubic light so that it interacts with more geometry than just the books (e.g. walls)?
Can you add more entities, such as a desk?

I suspect that the book surface is orthogonal to light rays and should not be lit at all.

The light volume already extends through the walls. And it's an ambient light (though I don't think the issue is limited to ambient lights).

I'll upload a new version with a couple more models, a paler material for the walls/floor/ceiling and a candle flame where the cubic light's origin is.

Edit: okay, attached. The staue I added looks good to me, but the top of the desk seems dubious.

I can see you're using the standard lights/ambientCube/skybox_industrial_01_cube from tdm_cubeLights.mtr

I think that light material is out of sync with the current TDM version

Basically, it looks broken

Let's move discussion into the forum thread for now
