Why isn't my project working in HTML5?


I’m trying to put together a project for a client that is a vehicle configurator. They want to be able to embed this configurator on to their website. I have built the project and packaged and deployed it in the Windows platform and it works perfectly.(See first screenshot) I have also built it for HTML5 and have tried to package and deploy the project as well. When I deploy it, I get the following results.(See second screenshot) Is it a polycount issue? I there some settings that I missed? What is going on and why is this happening? Please help! Thank you!
