Meshes[0] when import

I noticed there are many people get troubled with the meshes[0] recently. So is it not a good feature that root mesh to be a mesh rather than a transformnode, as many people won’t notice that meshes[0] don’t have vertex data when they come to BJS for the first time? And how to get them notice that? It seems it is not enough to mention this on the document.

Converting to a TransformNode seems the right approach but we are worried about all the potential back compat issues this could create.

I think @bghgary looked into it a little back ?

It is really a break change and I guess it will be a big issue for the peoject I’m working, hope there will be some more soft ways handling this.

Yes, the problem is backwards compatibility. Maybe better documentation would help?
