Maxwell render nodes are quits across network when no UVW coordinates are found in the scene in cooperative mode. We do not know what is it bug, or not?

It is not a bug.

It is a strict error telling you there is something potentially failing in you geometry.

Asfaik only network will stop the render @that point, locally or from plugin it might still start normally but you should see a console warning, at least if in verbose mode
