Hi tracers!

Finally, I managed to get my first fractal object rendered - a cube with

cubes in its corners with cubes in their corners with cubes in their
corners with cubes...

I also tried radiosity for the first time... but as I wanted to recur
deeper than just four levels, I constantly got the error message "Too
many nested objects" - despite only about 40.000 single cubes in the
scene, for which my 256 megs should be more than sufficient. Switching
of light and/or vista buffers had no effect on this, neither did
cancelling of auto bounding... so I really ask myself what goes wrong!

See you in Khyberspace!

...why? Honestly, three is probably sufficient, and two is probably good
enough for most scenes. More than that and the additional bounces
PROBABLY aren't going to have any visible difference on the scene, plus
you're just wasting memory and time, and probably creating more
radiosity artifacts to boot.

You're probably using union{} or merge{} statements that contain
the cubes. Try instead to declare each cube alone without braces
around it. That should solve the problem.

No, I neither use unions nor merges!
