Hello All. Pipeline question for you.

I've been having a ton of trouble exporting my model from CC3 until I found @victor.soupday's amazing plugin. It looks great once it is loaded there. 



the trouble begins when I export it out. Either back out as .fbx or to .GLTF.



GLTF imports back in with chaotic textures. skin is glossy, arms are weird, eyes are black.



.fbx with textures copied and embedded only exports the model w/ his eyes. 

any thoughts on the best way to get a clean export from CC3 to .GLTF? Am using the .GLTF format because I need it for a web 3D project in Babylon.js. 

I'm very new to all of this and any help is greatly appreciated. thank you.
