Hi and welcome to the forum!

For now we only support emission of billboards. Mesh objects can be used in the Hair mode though. Please refer to these user manual sections for more info.

Is there a way to interactively view the effects of changing nodes / node settings in animation, or do I have to keep checking the
results in the html output?

Hi!

The TIME node is Blend4Web-specific and so the results cannot be viewed in Blender. You can replace it with a generic Value node and animate it. Unfortunately Blender does not update its viewport for animated nodes (yeah this needs to be fixed by Blender devs). As a workaround you can switch to the Rendered mode and see the changes in a frame-by-frame way.

Also I'd recommend to all Blend4Web users to use SDK's viewer with open browser instead of exporting to HTMLs. This will provide you with a lot of additional information about what is going on. Also JSON+binary format is much more effective that HTML. See this tutorial for using the web player with external JSON files.
