I'm not really sure, if I've understood that, sorry. :)
So I had to use a max_trace_level of 7 instead of 5 and then I wouldn't have to
delete the window glass?

I'll post it. ;)
Thanks!
I thought it might be a problem, if the light source is surrounded by two sphere
sweeps, so there could be no light? Their texture isn't all transparent...
Don't want to confuse anybody by talking nonsense. ;)
Would it be better to post the whole scene (without image maps)?

Did you try compression?

I just do it the lazy way and use rad_def.inc.

Whenever you have a flat transparent object whose sides are hiden, and that 
object is colourless and transparent, you can just remove it.
You need it only if it also reflect something significant. This is the case of 
an interior night scene where the window reflect the room's content.
In the original render, the outside is relatively dark and the interior does 
have some reflection in the window: leave the glass.
In the second render, the outside is much brighter and would have drownd the 
reflection: revove the glass.

When you use radiosity, it's not only the max_trace_level that you need to 
increase, you also need to increase recusion_level by 2, as each encoutered 
surface count as a recursion_level.
What you can do, is to use the two pass technique.
On the first pass, you remove any weakly contributing transparent object and you 
use save_file. You can render this pass with a lower resolution and no aa.
On the second pass, you put back the transparent objects, set "always_sample 0" 
and load back the saved data with load_file.

Ok, Alain the bar is closing. Put down the drink. (jokingly I hope)


recursion_limit 3   // default 3
    // recursion levels are used to calculate the diffuse inter-reflection

    recusion_level not a key word.
also
recursion_level not a key word.


I could be wrong about all of this

No. No. I want to listen to it.
You don't have to stop. I'm happy to learn more. :)
Thanks for your tutoring.
I'll try this two pass. But at first, I'll have to read, how exactly to do that.
