AOV Multilayered EXR fail export

Hi, I'm a Cinema 4D user.

I am having a problem exporting a multilayer EXR file. My render size is 4000x4000 px.

I only have this problem when I add an Arnold Driver.

By the way, I have 64 GB of RAM and an i7 processor.

Thanks for your help.


Here is the console message :

How many AOVs?
Can you post a full log?


60770MG is 60GB, so you really don't have enough memory

I suspect you want to enable tiled exr output in the exr driver. That should dramatically reduce the memory used. If that didn't help, reducing the bucket size would be the next step.
