Now I am aware that this is somewhat of a niche scenarion, so bear with me:
When rendering out very large images (say for spherical panoramas @ 20x10k pixels or similar) the glare calculation crashes the render right before the image gets saved to disk. This is independent from having it harware accelerated or not and consistent across multiple machines. I don’t really know where the limit lies after which it dies, but currently the only workaround is to render a separate image at say 10k width and upres the glare pass. That error already existed in 3.6 and still is there in next.
Cheers, J
I don’t think I’ve come across this before.
Can you get us some more details:
- Maya version
- V-Ray version (if you can get us the exact build number - it’s printed in the Maya Output window, or you can get it from render settings > Settings > About)
- OS
- Hardware specs
- an example scene or some steps on how to reproduce this (I tried a simple 20Kx10K render with lens effects and it didn’t crash on a very old and slow video card with not a lot of memory).
- Is this a regular render inside Maya? Or a batch render? Or a render with V-Ray standalone?
- To what image format are you rendering?
- Are you rendering directly to disk without using a memory buffer (for very large resolutions)?
And lastly - do you happen to have a logs from the render when it crashed?
If you manage to crash it again, could you create a crash dump and send it over?
Hi Yolov - thanks for getting back to me and, most importantly, a very happy new year and great 2019 to you.
With regards to your questions:
\- Maya version - 2018.5
\- V-Ray version - Currently running v4.04.02.00010 of November 19th, 2018 but as I mentioned before this has been the vase with the latest versions of 3.6 before we upgraded as well.
\- OS - Win 10 pro
\- Hardware specs - tried this on thinkstations with dual xeon e5-2683 v3s / 64gb of ram and a 1080 as well as some HP Z820s with 64gb of ram and dual 1070s
\- an example scene or some steps on how to reproduce this - sure, this is going to be a big file. where to send it to?
\- Is this a regular render inside Maya? Or a batch render? Or a render with V-Ray standalone? - straight out of of maya. this is mostly due to the fact that lens effects only applied in the frame buffer in 3.6 IIRC...
\- To what image format are you rendering - exr or tif
\- Are you rendering directly to disk without using a memory buffer (for very large resolutions) - not sure. do you mean without the vray framebuffer?
Can you see if you can get me some logs?
Just happened again: Will send the log as PM, Yolov
