Pavel,
Thanks for answering my newbie question. Your documentation is very extensive, so I must have missed the fact that blender textures such as clouds, voronoi etc are not available. Hopefully something for the future.
The modifiers were specifically subdiv surf and deforming ones and they were applied, however this has only been once or twice and i can't reliably replicate it, but will let you know if i encounter it again.

Thanks for the help. You guys are doing amazing things, keep up the good work.

When I export a Blender project with B4W html, why do the resulting models not have any textures, materials, modifiers etc?
What am i missing?

Forgive me if this is already possible, but I would love to render some of my pre-existing models which aren't created with BlenderRender and therefor are exported by B4W as blank objects without modifiers or textures etc.
