just made a quick test:
4 diferent trees
each one duplicated 800 times
only instances
with cut out opacity
-render time 29 minutes
(i can’t upload more than a 95kb image so it’s on this link) http://img33.imageshack.us/img33/4548/29min.jpg
Jesus. Using only instances? I am amazed your com didnt run out of memory.
Anyway its gorgeous buddy. Just gorgeous

This is the point of instancing. It uses very little more RAM at rendertime than the original 4 trees would by themselves. And if you’re on a 64-bit machine (with Windows and Maya also 64-bit, of course), then it’s not an issue to push past the gigapoly level. I have yet to see terapolys, but I’m sure one could pull it off with less than 16GB of RAM.
But yes, those trees do look very nice and cleanly rendered!
Thank you all.
Kinematics: As far back as i remember the ram did’t passed the 2gb.
I have some more tests that i have made before this thread started, i will try to find them to post later.
A quick shading-test with techniques mostly picked up from this
extremly useful thread, trees are plain xfrog-ones.
And some grasstests to go with the trees:
PaintFX instancing would be my guess.
It’s some mighty impressive CG grass! Nailed the shading perfectly.
Amazing grass Visua, congratulations…!
Great example of the Mia translucency workflow,
discussed in this very useful, and informative thread…!
Pfx converted to poly and instanced with a Mr bynary proxy node, correct…?
Ciao…!:applause:
Alex
Simply amazing grass, especially the first render. This thread’s helped me a ton, too. Here’s some cheap and dirty palms made in Onyx, test rendering a scene-in-progress. Still need a lot of work on these, as palm leaves are a lot different than the broadleaf trees I’ve been playing with for the past months:
(I don’t know why CGTalk is resizing images, but I guess that’s cool…)
great visua 
infernalDarkness, the leaves looks great, i will give more detail to the palm trunks, some bump or displacement.
Alex, what about your book?? all we are looking for it
InfernalDarkness: i’ve made so me tests with palms and some other trees some time ago, using the same process as described here but softer.

Visua: Great grass shader. does it work that good on with diferent ilumination? front and back light?
Unbelievable thread!!! Soooo many things to learn, and exactly this kind of topic i was looking for!
Thanks to tostao_wayne, infernal, and everyone else who shared their progress and tips on how to approach this subject. Gonna give it a try in next few days, and i really hope i’ll get some results.
Now i’ll go and read the thread from the begining… 
btw, beautifull renders, and i also liked the renders from Visua, so Visua, could you give as a brief setup of those renders…is it the same things that is already talked about in a thread, or you’ve made something different?
If you have a box with a binaryProxy node attached to it and you instance that box, the binaryProxy node doesn’t work at all, am I missing something?.
Thank’s.
yes if you first group the box, and instances the group.
or uses a script to reconnect the binaryProxy to the instances.
Don’t know how the hell did you figure out that…, very impressive Tostao.
But, the 9 binaryProxy nodes issue remains the same with that method too…
