Can 3D Game Kit Play in Web?

I have created scenes with teleport points between different areas and scenes. I built and ran the game with WebGL, and guess what happened?

The game runs, but large mesh renderings when black, which I think means it cannot rendered. 
Have I done something in my scene along with the editing that causes the blackness?

I used the original scenes to find out and tried to build again. The result is the same: all the large meshes went black. I think the game kit is not meant to run in browsers.

Well, until I have time to redesign the game scene with less GPU. I think that is it.
