Main feature is non standard character export to CC4.
With armature select, the Export Non Standard button will export the character and generate JSON data to reconstruct the character's materials correctly with the CC4 Blender Tools plugin (1.0.7).
(Mainly works with Prinicpled BSDF based shaders, input channels will be stored or baked as textures. For non BSDF materials it will attempt to match texture/image names with the PBR channels.)

I've also expanded the Import Character button to import more file types (FBX, GLTF, GLB, VRM). This allows for converting certain character model types. (Only VRoid VRM are handled differently at the moment, but it can be expanded later.)



Also, when exporting non standard characters, if the rig is detected as an Auto-Rig Pro control rig, the add-on will invoke the ARP export operator rather than the base FBX exporter, which means the character skeleton will be cleaned nicely up for CC4.



It's all a bit experimental at the moment so bear with any bugs. There are so many different possibilties, this could take a while to get right.
