Serializing any Object3D with nested NodeMaterial throws error

See original GitHub issue

Describe the bug

As the toJSON method on a THREE Node expects a nodes field in the meta object, it throws an error if the meta comes from an Object3D which never supplies that field.

To Reproduce

Steps to reproduce the behavior:

Setup a simple THREE project
Add a mesh to the scene with a NodeMaterial
Serialize scene using scene.toJSON()

Live example

See Sandbox example

Expected behavior

Object3D should serialize just fine. Solution would be to include a nodes field in the default meta-object.

@Mugen87 Thanks for clarifying. I managed to get an alternative workflow up and running using the NodeMaterialLoader. However, TypeScript definitions for NodeMaterialLoader seem to be missing. Let me know if you want me to track that separately.
