Corrupt meshes in HTML5

Hi, when I build my project for HTML5, my meshes get corrupted and look like this:

Note that the geometry is messed up…

It looks like this in editor:

Does anyone know what is causing this?

Additionally, when I build for windows it looks like this:
(like the reflections and lighting is not working correctly)

I am using the 4.4.0 Preview, and have tried increasing the amount of memory available to the HTML5 build, which done nothing. I am running the HTML5 version in Nightly.

I have set the scalability options to their minimums and maximums through blueprints, but neither solves the problems.

For anyone else getting problems like these, I ended up solving it a bit.

The corrupted mesh I believe was caused because the polycount was too high, I had imported that as a test and it was 70,000 polygons. As separate meshes they no longer are corrupted/distorted.

The lack of reflections, I think, is just that the reflection is lower resolution and so it is more blurred and harder to see. I decreased the roughness of the metal to make the reflection more obvious and it was actually there, just low quality.
