3000 seat's and a headache....

[DP]

are all the seats seperate parts? when poly counts get high we find collapsing them to editable mesh helps and attaching them to each other helps reduce the object count. It seems max has more of a problem with large object counts before large poly counts...

may help..

Shouldn't those seats be instances of each other anyway?
Rendering with instanciate should make this possible.
Anyway, you should maybe delete all the seats not inside the camera view for each shot you need to do. There should be quite a few you can get rid of for this specific angle. Or have you already removed them?
The ones in this view can't possibly count 3000?

Sunny- Where is the bitmap pager you are talking about?

[sunnyc1]

I'd have to agree with Trixian. Perhaps you don't need all 3000 seats in the view.

For the Bitmap Pager, go to Preferences, Rendering and then at the bottom right corner you'll see a tick box for Bitmap Pager. I think it's off by default. To be honest I'm not 100% sure what's it's function is, I just know that it helps sometimes. I'm sure someone else more knowledgeable on this forum can explain what's purpose is and more importantly what settings to use.

Thanks for that Sunny!
I have a large scene that sometimes renders, but mostly crashes!

Vray is great, but not when it comes to large scenes.

Da Elf- what was your setup for your 40-50million poly scene?

No worries Chris.

By the way, it doesn't look like I'm going to make it to Melbourne next week. Way too much work on at the moment.

Perhaps you can swing by sydney sometime?

We did a similar project a couple of years ago. It was a pain in the ass to render as it was over 20.000 chairs on our Dual Pentium III at that time, using Vray 0.5 Beta I guess that today it would be no sweat by instancing, as we have done projects with over 60 million poly instanced trees . Our images can be seen at:

The most important thing is:

- keep the geometry of the chairs as low as possible.
- keep the geometry of the chairs as low as possible.
- keep the geometry of the chairs as low as possible.

Besides this,
- try using instancing
- Maybe use a Xref with a Box as proxy
- Make sure you have at least 1 or 2 GB of RAM to handle the geometry
- Try to store to irradiance maps on vray lights or use self illum. geometry to make bucketting much faster.

If it still crashes on rendering, consider rendering by passes. one pass per group of chairs, and the composite on photoshop or after effects.

Hope it helps. Via

zerofractal. i remember that image of the concert hall or whatever it was. lovely image even by todays standards hehe. those were the good old days of beta testing.
actually speaking of which. sorry about not having a miricle setting that can help you jacks but i used tonnes of proxy objects in vray 1.45.20 thats the only way i could get that scene to render

[sunnyc1]

Hi Alejandro,

Nice work dude. Very nice. You've got a darn quick website too.
Well done.

Thanks sunny. I just hope this pointers somehow helo reza. BTW the renders on that times were done at 1024x768 and took about 15 hr each to render. I believe it would be a much quicker task for today's Vray and CPUs.

Da Elf, I am waiting for 1.5 to come out for the vray proxy feature. It will help me out quite a lot! I was not lucky enought to get a copy of the internal version. Is the vray proxy feature easy to use?

thank you guys...im still trying...just got a few extra rams...and reduse some of the geometry...problem is its going to be an animation....short 1..
by the way i redid the material just to be safe...problem is i wont know what happened or what went wrong...

[moruh]

cuba ko try ejas:
1-material raytrace- take out little bit
2-vray lighting shadow parameters/subdivs cuba ko reduce jadikan at least 5
3-bila open 3d file tu, go a head just render, dont touch anything coz can reduce memory windows/ slalu aku wat cam ni.
4-yup reduce some geometry
5-keep ur pc cool enough if u notice that xeon HT will slow/drag/hang if cpu is hot, experience when i overclock dual xeon 2.8ghz to 3.4ghz but running in waterchild heatsink. laju gaks bro!
