Yes indeed! Thanks, Robert, for continuing to 'obsess' over your AO stuff. Very
inspiring.

I wonder how would MCPov do in this case. In almost 100 hours you might
get very good results with it in this scene.

Yes, I've been meaning to experiment with MCPov a bit more, but time has been
rather tight for me lately.
As it turns out, it was the massive focal blur along with radiosity normals that
were slowing things down so much. Here's another version I did today using the
Stanford Lucy statue. The AO and regular passes for this version rendered in
just over 6 hours (for both) with minimal focal blur and radiosity normals off.
Cheers,

Aaaah!!! I love this one!! With focal blur just as I prefer it too!!
Excellent, Robert!!

Fantastic!
My only gripe is that the bricks should be dirtied up a lot to make the Ivy
believable.

Really beautiful.
I was wondering how you imported the Lucy statue into POV-Ray. I went to the
Stanford 3D Scanning Repository (one source for Lucy), took a look at the PLY
file format stuff there, then went to PoseRay to see if it could import PLY
files. But it doesn't. Did you do an intermediate step, like using MeshLab?

Blender imports PLY. I used it to import the standford bunny and then
use a low-res version of it in a povray scene "radiosity and bunnies",
in p.b.i...

Yep, I used MeshLab to convert to OBJ, and PoseRay to convert OBJ to Mesh2.
