high resolution render fail

[aweidenhammer]

Is there a reason to have a separate vray common tab, instead of using the maya common tab? It's a pain when I'm using multiple renderers in the same scene, since they don't sync. especially camera settings. Had a bunch of failed renders based on not having the same output and camera settings duped to both common tabs.

you may need to render to .vrimage in order to get this res saved.

Hires problems

you may need to render to .vrimage in order to get this res saved.

So after some more testing, my initial problem was user error, but now I am having other problems...

Any render over 15000 pixels won't seem to render using all cores, or at all, I didn't have the patience to let it go all day. Basically, it is hanging before getting a framebuffer displayed. I am using a simple flat-shaded sphere as a test.

I'm using standalone with .vrscene files. I've tried writing to exr and vrimage files, with and without framebuffer... but nothing over 15k seems to render on this machine.

dual Xeon nahalem (8-cores) non-hyperthreaded, 12 gigs ram. Dynamic memory settings have been upped to 2/3 of physical ram, but that didn't really make a difference. 15k rendered no matter what dynamic ram was set to.

You can try to render to a .vrimg file through the standalone, but you will have to also modify the .vrscene a bit to disable the memory frame buffer. For this you need to find the SettingsOutput plugin and add the following options to it:

SettingsOutput {
  ....
  img_file="path/to/file/name.exr"; // File name; should be an .exr or .vrimg file
  img_rawFile=1; // Write a tiled image
  img_rawFileVFB=2; // Only show a preview of the image, do not store all of it in RAM
  ....
}

Awesome Vlado. Thanks! That worked. 18k is rendering without using much ram. Looks like I can go higher!

Hi vlado, is it possible to do this settings directly in Maya ?

It's called "Memory frame buffer" in the VRayCommon tab.
