This is a simple scene I've modelled for test purposes in truespace 6.6. I'd appreciate any credit for its use, or use of any of my own individual models. 
The images shown used radiosity solutions over 99%.
Solutions took several hours on an 800MHz slow PC (daytime considerably faster than night scene, which used light illuminting surfaces instead).
Hope this is of some use.

Please report any problems asap.
