I would like to create WebGL applications and use Blender as a modelling tool. I don't necessarily need to translate game engine functionality to WebGL but I would like to retain as much of the UV mapping, vertex colors, materials, etc. info as possible.
I already know I should keep the polygon count low. What are the other things I should keep an eye on? (Such as
don't use feature X because you won't be able to export it)
What tools do I need to learn? (WebGL framework specific plugins, generic tools like OBJ exporter)
