How does one set up bryce or Poser so that a model is the source of the light and it radiates in all directions(ie. a torch)? Is that a parenting issue? I've tried the spotlight setting but haven't had much luck.

Hmmm. I think what you need (bryce) is a radial light source instead of a spotlight? Not sure with poser.

Bryce lighting is kinda weak, there really is no "ambient" lighting as there is in PovRay and other programs. The best you can do is like bladesmith said, use radial light close to the desired source. Some atmosphere will help the effect. Also, if you can find Clay's Volumetric Fire, it's by far the best flames out there. And if you turn up the ambience, it will emit light as you can see reflected on the mans body in the image.

Ok, thanks for the info guys. :-)

OK, Prizm... that's not quite accurate. Clay's Volumetric fire, like all other material textures, does NOT emit light. Sorry. What you're seeing is reflection on the man's face... he must have a reflective material put on. The other drawback is that in order to have the fire material 'glow' without its own light source, the Ambient Color setting (in the Atmospheric settings) must be set to a reasonably bright color... the volumetric fire material has high Ambience values, but they can't produce any ambience that's not in the atmosphere. In Bryce, at least, the only objects which will emit light are the light primitives. The easy way to have an object (like a torch flame) emitting light is to place a radial light inside it... and then in the material for the torch flame (you can use Clay's fire, it's pretty darn good) select "disable Receive Shadows".

You are right, his texture has high specularity. I guess the best you can get is a reflection, either on the object or in the atmosphere, as you mentioned. Thx :)

Ok, That make a little more sense. Thanks for the help everyone. :-)
