Hello.
I'm finishing two projects and we have two plans that we can't render....
Both plans have in common that they use mash with many instances (one with about 3.000.000 and the other with about 200.000).
The one with more instances we have done it with orbx.proxy and the one with less in a traditional way (with mash and objects).
In the maya viewer both are rendered and work fine.
When we try to export them to orbx (only camera animation) we see how the memory is filling up until it closes (we are talking about 128GB of memory in a scene that when it is rendering in maya does not exceed 35 Gb). When we have tried with a workstation with more memory (256Gb), there comes a time when it is blocked and does not write anything to disk.
As a workaround we decided to render it directly in maya... But when we launch the render everything goes well except when the file format is EXR... In that case the maya script editor prints the file path... But the file does not exist on the disk!
If we render with another type of file (png for example) everything is perfect.
I have tried to render something very basic (a cube with sun) in exr, and the same thing happens... (attached scene).
We need EXR because it is the only one that handles 32 bits. If I put tiff it doesn't let me choose any bit depth and renders it in 8bits. If I put it in png it works fine... But there are only up to 16 bits...
I have a very tight deadline...
