Sure thing. Try this script LayersToFBX_cmd.py (8.4 KB) on this file. guid error.zip (9.4 MB)
At the input, Select the layer called Error and accept default options.
The script goes through the layers selected, mesh the objects, join the meshes according to materials and then exports as FBX. But for some reason this bunch of meshes returns a 0-guid from JoinMeshes and I’m not sure how to error check for it…
I’m travelling and haven’t had a chance to try what you suggest. But just from what you write, would it be possible for me to do error handling after the Mesh command in the script to pick up on bad objects there before feeding them into Join?
