I should make a render that is 20K pixels wide. I am running out of memory at the early preparing stages. I have 32 gigs of ram. Even if I try to region render smaller area I run out of memory. Any ideas how I could make this work? Should I render irradiance pass at lower resolution and then render at the final resolution. Does that give any momery help?
In render settings under VFB there is a section to display “preview only”. Type in the resolution in this window (untick get resolution from max). Make sure you save the image in this section. Either vrimg or exr.
In max, type something small like 2 X 2 (just so that nothing is in ram there)
Render. It will give you a small preview of the render while actually rendering large. Give it a quick test with a region
With this technique render elements won’t show on vfb and they won’t render directly to folders either. So I guess I have to enable something that was disabled with this technique?
If I enable memory frame buffer then it works ok but ain’t the whole idea of this technique to disable memory frame buffer?

With these settings all channels will be rendered in one EXR file , after that you can split that by native VRay tools i think , or find a simple CMD line open source tool to split into render elements. Or open VRImg file in VRayFrameBuffer and save those one by one (never tried that though might work)
