Does Redshift have something like .map or .tx for textures? and what
about standins/procedurals? I think those are essentials for big
productions, not even thinking on massive productions, just bigger
than simple scenes... If it has (or plan to implement) something
like that, I would say it's a serious contender, but if not, I think
it's aimming to small studios or freelancers only, which of course is
not a bad thing at all, just saying it shouldn't be compared to other
renderers just because, well, they are renderers...

@ 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?
