Sorry for the delay, this one is a bit more complicated than usual.

I'm getting a warning:
LIB: material 001-Rough-Wood-Bois missing from addons/materials_library_vx/Wood.blend
All used textures and materials must be contained in the .blend-file itself since we don't have any addons on the farm.
That said, it seems to be rendering just fine, so maybe we will try it anyways.

There only seems to be one RGBA layer in the multilayer EXR output (the rendered scene), is that intentional?

Multilayer EXR is still experimental, not sure what we will get out of this - the preview may be black

My windows machines were getting plenty of work at first, but now nothing. The job is only ~10% done, as I post this. If the remaining ~90% are linux-only, please let us know.

There only seems to be one RGBA layer in the multilayer EXR output (the rendered scene), is that intentional?

My bad, it does indeed seem to contain all the information. That's pretty cool, I didn't know you could store the entire compositor state like that.

It prompts the question, what on earth should the preview show in a situation like this? The server doesn't know which layers are the RGBA layers for the output (or if there are any colour layers), it just gets a whole bunch of individual colour channels, some of which are part of the ambient occlusion, some part of the mist, some part of UV etc... Maybe a stitch of all the layers next to each other in greyscale? Hm...

Switching the rest of this session to best effort validation since it seems to generate a lot of results that do not match.
