I "played" with pov long time ago on my Atari falcon but I have not been 
using it for about 6 years...


Yes, you understood... I'm trying to do what Christoph does in his tunnel 
scene. I dnd all the files, but I can't manage to put the bricks randomly 
around the cylinder. Could someone explain it to me ?

Second, I find that the brick is quite dark... do I have to increase the 
ambient parameter ?

Thank you.

If you're going to do a textured brickwork, the easiest way to make it
look random is to use a paint program, so that you can put the bricks where
you want.  Then wrap the image around a cylinder using a cylindrical
projection for the image_map.

John
