Exception: error, no selected mesh objects

[AwokeKnowing]

Hi guys, I got this trying to export my scene in blender 2.81 (first time I tried the tool). It exported a bunch of images, but for some reason the mesh part fails it seems.

Traceback (most recent call last):

I noticed there were no export settings. It said something about finding the settings in the properties panel

Basically, your material is not directly represent-able in BJS's implementation of PBR, It is trying to bake right in the export itself. Have not tried baking 2.81. Wonder if it is changed?

The exporter is trying to add a UV, since there is none. You might look further up the log to find the mesh it was working on, and add the UV yourself. Even better would be to see what node is was complaining about & adjust. Principled is your friend.

There are property subsections for the exporter all inside world, mesh, cameras, lights, materials.
