System Information
Operating system: Windows 10 x64
Graphics card: NVIDIA Geforce 965m

Blender Version
Broken: (example: 2.80, edbf15d3c044, master, 2018-11-28, as found on the splash screen)
Worked: (newest version of Blender that worked as expected)

Short description of error
When exporting meshes from Blender to gLTF 2.0 using DRACO compression, it seems to corrupt all the materials except for one. I did the same process using Blender 2.81 and it worked as expected.

Exact steps for others to reproduce the error
Select multiple meshes that each have a basic Principle BSDF shader with an image texture for Diffuse, select export to gLTF 2.0, then select gLTF Binary (.glb), include selected objects and enable Compression under Geometry. If you view you exported file with https://sandbox.babylonjs.com/ you should see the issue.
