Sketchfab adds beta support for Blender 2.80

Right after the Blender 2.80 release, Sketchfab announced their support for the new 2.80 file format.
We now support direct upload of Blender 2.80 files. Please note that this support is still in beta and has a number of known limitations.
Known issues/restrictions
- We currently support the Principled BSDF Shader node, and its attached textures, if there is not a mix of random nodes between them and the PBR input
- Complex animations may break: we don’t yet bake all types of animations, like constrained objects, etc. You may have to do this by hand and even then your results may vary.
- Models with very large images (4K – 8K) are crashing when being processed.
- Our Blender exporter plugin has not been updated for 2.80 yet.

“…mix of random nodes…”? Does this mean do not include nodes between image nodes and the principled BSDF?
