that helps with the actual OBJECTS...but I'm trying to
find a good LIGHT source to define. I'm using media, and
spheres to create a nice fire. But the light source seems
fake. I'm trying an area light...but that doesn't seem to
work right either.
I appreciate the tip on how to define the fire such that it
interacts with the light right....but what kind of actual
light source is best? just a regular light?
