Missing Node Issue 3D Studio Max

[freetoplay]

Using the 3D Studio Max Exporter, I still get a missing Node warning, not sure if this is related to the exporter or not?

It seems like a default light mesh is added by default for some reason.

Hi @freetoplay.  The missing node warning means that there is a node in the glTF file that is not used.  In this case, it is caused by a default ambient light created in the 3ds Max exporter, which is not supported in glTF.  The way the exporter was authored, it writes out a glTF node, and then checks to see what kind of node it is.  Ideally, it should do the reverse: check the type of node and specify if it should be written to the file or not. 

In either case, this isn't an error so the file should work, though I plan on refactoring that code to make it do the reverse.  This will take some work since I would have to rewrite a few functions, but shouldn't be too difficult.  Let me know if you have questions on this!
