You rock, I modified the HtmlX.template file with the your code and it worked perfectly. Thank you very much. I know next to nothing about emscripten or javascript for that matter, so that presents a problem when dealing with HTML5 development through UE4. Now if I could only get UE4 to not upload uncompressed files to the S3, I would be in good shape for automating this process. Anyways, thanks again.
