Hello,
From time to time, the unofficial Blender Exporter fails to export the .obj and/or .mtl.
It happens. In this case, we get the message, from within the Blender api : "something wrong happened, please check console logs...".
So I open a new blender panel called python Console, to check what 's wrong and... there's nothing in it. Nothing related to the obj export.
Am I doing something wrong here ?
