almost 1300 trees test

[nlo]

since i still work with max5 and working with so many polygons did not really work (freezing max5 viewport), i asked a friend to render a forest scene with vray and max8

there are 4 types of trees (onyx) all between 120000 and 170000 polygons...

trees are instances - not proxies and dyn memory was used.
no 3gb switch was used and luckily there were no memory issues.

image didnt work

Looks really good, I would have him try using them as Vray Proxies, because that greatly increased the speed of my renderings, not to mention the speed of working in the file itself. 2h21m56.2s is nowhere close to acceptable for animation frames.... if that's what your doing, that what I have to work with.

If I understand proxies’ right they wouldn't work in a view that shows all the trees anyway as it still has to loads all the trees and not just the ones in render view. Let me know if I'm wrong.

But the trees look great. If you never get really close to them maybe you can reduce the poly count for faster render.

It is a shame to have such nice trees and such tiles grass together

all a proxie really is is a place holder for an object. if an object isnt in your scene then the scene is pretty small. if the scene is small then it uses less ram. so if you had a forest of trees all mesh then when you goto render the big scene file is using up memory. then it needs to convert everything to be able to render it and that also takes ram. with proxies. tiny scene file taking up small amount of ram, yet when you goto render the files are called up. this will take up ram however your total ram usage is less since the scene file was small.

yeah use vray proxies. I did a test with 10000 proxied trees (only 1 type) and it took 2 mins to render at an animation frame resolution. I didnt get the exact memory usage but it was low.

the example you have looks very nice though!

[nlo]

this scene was really just a test and rendertime was not really considered.

for animation 2h is way off and if proxys really make such a difference, it would be great. 2 min would to good to be true. paulison, did this include irradiance map calculation?

i was just happy to see that there were no memory issues.

One of the guys here is doing something similar with around 4.5 million polygons so I'll be looking at ways to speed this up. Are the leaves on the trees polygons or are they opacity maps? Also are you using motion blur?

[Da_elf]

i believe the most ive ever rendered was 80 million and i was using proxies to help me out.

[nlo]

if i'm not totaly stupid the number of polygons could be somewhere around 200 millions... its around 150000x1300

leaves have opacity mapping, no moblur, QMC-AA w. catmullrom for crisp

That and having to save it as a JPG, do PNGs work here?

[joconnell]

Eek - thats a nasty amount of data...
