How do I get my Cycles materials into blend4web? Just downloaded and installed blend4web.  Very nice tool.

Have a nicely textured model in Cycles, but when I export to .html it is all black.  No materials, no lighting.

Couldn't find beginner tutorial how to apply materials.  Could someone please describe what we need to do?

I hope it does not involve baking the textures.  Would like a simpler way.
Thanks
In Blender there is the Cycles render engine (non-real-time) and the GLSL viewport (real-time). Both has its own set of material nodes. Blend4Web is a real-time engine and thus leverages the viewport's nodes.
