So I've been working on this for several months now (off and on) and it's
nowhere near finished.

The problem I'm having is that even with the crummy radiosity settings I used on
this render, it took several days.  The reason for this, I think, is the
combination of the lighting and the water (I know the water needs work).

I've been experimenting with pure radiosity for lighting, but I'm having trouble
getting good illumination from flames. I've tried pumping the emission (media)
as high as 1200, but as soon as I try to add color to the flames the light all
but vanishes.

I hadn't really wanted to show this off yet, but I need help with the lighting.

This render uses conventional lighting but, as I said, it was slow.

Regards,
A.D.B.

Are the spirals parametrics?
Lanuhum also complained about long render times with parametrics.

The columns are isosurfaces.

The render time for the columns is nothing compared to the water when the
lighting is turned on.

Does the water have a diffuse component?

That bugs me. How come water should have such an impact on radiosity
render times? That can't be, can it?

According to the other thread the water renders slowly even
without radiosity. It might be due to the blurry reflections/normals
in combination with anti-aliasing.

As I understand it, the problem is the six light sources ( real ones, not
radiant objects) surrounding the pool.  Perhaps there's some optimization
possible when dealing with multiple light sources affecting a common area?

Maybe I can express my opinion.
Once I rendered a scene with large area surfaces that switched the
specular/phong on. The multiple light sources can make it slow truely.
I only have the experience that time. Because I almost use the reflection
instead of specular.

This only gives good results of you use photons, and I've never had good results
with photons.
