UNable to batch render because of image format

[ciboulot]

Hello guys,

I have a very strange error when batch rendering. THe rendering is processing, but at the end, the image is not written with this error:
0: STDOUT: Error: Octane: Error writing untonemapped OpenEXR image.
I have checked in the render globals, and I'm set to tiff16 as image format.
Nonetheless, I found in the outliner (with "dag objects on") the node octanesettings. In this one there an option for the image format:
PNG 8
PNG 16
EXR
EXR-tonemapped

I have to render 22 shots with Octane, and I know it can work, but I don't see what I'm missing.

Thanks for your help guys.

Ok so,

I investigated myself on this one and discovered one thing:

Octane apparently doesn't like long filename prefix:
<Scene>/<RenderLayer>/<RenderLayer>_<Scene>.
This was my filename prefix rule. And it didn't want to write any image!

As soon as I deleted the first argument (<scene>), there wasn't any more problem.

I don't know why, there wasn't any illlegal character, the path is maybe juste a little bit long, but nothing fancy.

Problem solved, but I think it worth to investigate further I think
