Note to self: WARNING [com.jme3.scene.plugins.OBJLoader]: smoothing groups are not supported, statement ignored: s

How annoying. The smoothing groups warning comes from the OBJLoader class (part of jme). The teapot comes from the testdata project. I can't solve the issue without involving core.

Yeah, I tried once to check these. To optimize the OBJLoader on jME. But didn't get so much out of it that just stopped. Most of the support is already there. For all the meaningful stuff and it mostly works, mostly. And it is a bit legacy already...

Can we switch to GLTF teapot model?

There is no gltf teapot. Just ogre xml. We can of course provide one with the sdk.
I'm thinking it should have a set of assets of its own, anyway.

This would be a big change, but could we just not show warnings as dialogs?
