@ Eugen... I think I lit that with a dome light... honestly I can't
remember though....
@ Steve... yep I hear I ya. Rest assured, we're not doing anything close
to elysium, and as I said not even as big as Athens. And it's cartoony,
so although it has a lot of detail, the shading is exaggerated.
@ Andreas... no, Redshift cannot combine the ram from the cards. If you
have 3x6GB, you have 6GB. As for mass-rendering, we've already begun to
outfit our farm with more GPU boxes. We're a small operation here, so
our node numbers are low, but we definitely have to be able to
mass-render frames. We have a history of CPU rendering with Mental Ray,
and we're used to a certain volume. For us, the question isn't really
the render time per frame, but per shot. And so far, even with the heavy
scenes I descibed in my previous email, I think 35min may be the longest
time my single-Titan has taken at 1920x1080 full MC. With multi-GPU
machines (which is not an easy thing to figure out, either), we could
get through these shots in very short order. I don't know whether it's
the fact that RS is on the GPU, or whether it's RS' actual techniques
(probably both), but we're getting great renders in very fast times. And
we're using Redshift with Royal Render perfectly well. The Redshift guys
worked with us to implement some environment variables so we can pull
from a central location. It works well on the farm, and is stupid easy
to update.

yep, looks nice.
I'm also wondering if redshift can use the combined vram when using
several cards in sli mode, if you have 3 titans, can you use 3x6gb or
just 6gb for your scene?
a tree scene like that, at that rez would probably take a few hours in
arnold or vray, so even at 30m in redshift it's still very fast..
still, at 30m a frame you won't exactly be able to render full shots
without a farm, and once you work with even heavier scenes I imagine
you are looking at rendertimes of several hours per frame, and at that
point I don't think the gpu will speed anything up, quite the opposite.

To be clear, when Redshift goes out-of-core, it goes /into /your
system ram. So in the end, you still need plenty of system ram
for large scenes. But I've only got 20GB in my workstation and
I'm getting very complex renders out of it without coming even
close to that. More in the 6-8GB range so far. Proxies are
awesome, and Redshift wisely had those from day one of the alpha.
Now several months ago I rendered this
<http://timcrowson.smugmug.com/photos/i-qGFB7nv/1/O/i-qGFB7nv.jpg>,
but it's more along the lines of what Octavian posted. It's just
one tree instanced a bunch of times. This rendered in about 30min
at that resolution, on a GTX470.

Very nice!! How did you light it? Sun + dome?
