Have there been any improvements since 4.10 for html 5?

Hi, I do arch vis, and I tried creating a html 5 walkthrough a few years ago with unreal. The desktop version worked great, but the html5 version was an absolute nightmare, missing textures, bad lighting, no reflections, inability to run smoothly with even small scenes, etc.

Have there been any improvements over the last few years in this area, or is shapespark the better option currently?
