Oh, one more thing. To properly get the effect of a flame as a light source, you need to take into account the inverse-square falloff. Light intensity decreases with the square of the difference.

Poser doesn't implement this, but by putting a shader on a light, you can actually get it to do that properly.

In your render, the falloff of the light along the wall was due to the angle change, not the distance. If you gamma correct you can suddenly see that a point light or spot light is illuminating the surface too evenly. This was compensated for by the way your monitor darkened some parts of the walls, creating the illusion that you had the inverse square falloff going. But many things are much more realistic if you actually do all the physics correctly.

Renderosity forum reply notifications are wonky. If I read a follow-up in a thread, but I don't myself reply, then notifications no longer happen AT ALL on that thread. So if I seem to be ignoring a question, that's why. (Updated September 23, 2019)
