Maximum resolution for rendering

[EdHarriss]

- There is no limit.
- Maybe you are running out of contigous ram.
- Try dragging your scene onto the XSIBatch icon instead of rendering inside XSI.
- Or, convert your textures to .map files.

thankyou ed... I will try this when I get home!

will post result of experimentation...

I've had problems rendering high res images, so I might be able to help you.
I found I could render the file at 3000k but couldn't render it at 4500k. I trouble shooted my scene, I went through all the effects I had on.
Photons, FG, displacement, glossie materials, you name it, they were all on. (I do mainly Arch Vis.)
I found that Fine Displacement was the problem, it wouldn't render passed a certian res.
So I turned it off and the scene would render 4500k. So if you have displacement on, try turning it off. Try using normal maps.
Bye the way I had a chat with Softimage support and they know theres a problem rendering high res stills.

thanks furiousD

hopefully it will be adressed in 4.01 http://cgtalk.com/images/smilies/thumbsup.gif

Also try using the subregion rendering options... rendering a 16000x8000 image in little 1600x800 chunks, and then assembling in PS (etc) can be quite handy.

yep I tried the subregion root and it didn't make a difference with fine displacement.
Kind of strange, i thought fine displacement would only displace the subregion part of the image.

I don't do a lot of displacement, so I really can't comment, but thru tweaking BSP settings, AA settings and optimising textures (.map) I can usually get anything to render out.

Hope you find a way.

JDex,
I did get it to work, just not with displacement, Mental Ray keeps on loading and unloading .map files like crazy. After it does that a couple a hundred times it crashes.
So I went with a bump map, seem to do the trick.

I also had problems with rendering large amount of displacement.

[Changeling]

Is it possible to 'freeze' the effect of the displacement map, and then remove it from the render tree? (sort of save the displaced poly)

certainly possible in MAX, as displacement was one of the stack operators...

Hi
I don't think so, what you can do is use Em_diplacer (free good plugin) that will make a real displacement polygon and then you will have a high resolution displaced object. You can find it here

Hope it helps:)
