Though it's working fin in Chrome and FF: http://webgl.garyritchie.com/frm/frm_elongated/

support of roughness for reflections is still experimental and in developing, for now roughness only affects direct lighting, not environment. But we are working hard on it

I will make a presentation on our pbr/cycles plans which will also address this theme in the upcoming b4w conference

Sounds great, I'll be watching remotely. Cheers!

Thanks Konstantin, that helps to confirm what I was attempting. It seems I had wrong expectations for how this feature would work and that I'll still need to do appropriate texture set-up to simulate image-based lighting. I'm still learning.

My expectation was that there would be some lighting going on, similar to Cycles (top left.) On an object with ~0.8 roughness I wouldn't expect so much reflection (top right.)

Got the new RC but I'm having a difficult time replicating the example in the recent tweet: https://twitter.com/blend4web/status/856536053947256833

Anyone have a blend they'd like to share?

Thanks!

linking materials to objects is not supported. Is it important setting for your pipeline?

Not any longer. We made a script for Blender that moves the data from the object to the material.

Looking forward to spending more time with B4W. Thanks guys!

Error: Incomplete mesh; Material slot is empty

This occurs on objects where the material is applied to the object.

Is there a requirement to attach the material to the data slot?

Currently working out how to get SketchUp models (with some textures) into Blender. Do some cleanup, and export to WebGL. My team is currently using Google SketchUp 8 on Windows; Blender 2.72b on Windows and Ubuntu 14.04 with the Blend4Web addon v14.10.

Collada from SU into Blender but will try with OBJ…
