Hi,

      I packed unreal demo project to Html5. But, when i tried to run it on chrome => "Does not support webassembly" Mozila Firefox => TypeError : xhr.response is nullI have no idea about both of this.

``If anyone know about fix/ faced similar kind of issues, share your approach.

Does http://mzl.la/webassemblydemo work for you, and runs with WebAssembly? (that is, does not print a warning message about lack of WebAssembly support?) Do you have latest Firefox version installed?

Above link works fine in chrome and in firefox it shows ‘RuntimeError: index out of bounds’. I’m using the latest version of browser(both).

Hmm, nothing comes to mind here that would be a known cause. If you have a small test case of your project, that might be useful to try to reproduce.

I was having this exact issue, this is the .htaccess code that worked for me (for Apache servers):

<IfModule mod_headers.c>
    RewriteCond "%{HTTP:Accept-encoding}" "gzip"
    RewriteCond "%{REQUEST_FILENAME}\gz" -s
    RewriteRule "^(.*)\.css" "$1\.cssgz" [QSA]

    RewriteCond "%{HTTP:Accept-encoding}" "gzip"
    RewriteCond "%{REQUEST_FILENAME}\gz" -s
    RewriteRule "^(.*)\.js" "$1\.jsgz" [QSA]

    RewriteCond "%{HTTP:Accept-encoding}" "gzip"
    RewriteCond "%{REQUEST_FILENAME}\gz" -s
    RewriteRule "^(.*)\.data" "$1\.datagz" [QSA]

    RewriteCond "%{HTTP:Accept-encoding}" "gzip"
    RewriteCond "%{REQUEST_FILENAME}\gz" -s
    RewriteRule "^(.*)\.wasm" "$1\.wasmgz" [QSA]


    # Serve correct content types, and prevent mod_deflate double gzip.
    RewriteRule "\.cssgz$" "-" [T=text/css,E=no-gzip:1]
    RewriteRule "\.jsgz$" "-" [T=text/javascript,E=no-gzip:1]
    RewriteRule "\.wasmgz$" "-" [T=text/javascript,E=no-gzip:1]
    RewriteRule "\.datagz$" "-" [T=text/javascript,E=no-gzip:1]


    <FilesMatch "(\.jsgz|\.cssgz|\.wasmgz|\.datagz)$">
      # Serve correct encoding type.
      Header append Content-Encoding gzip

      # Force proxies to cache gzipped & 
      # non-gzipped css/js files separately.
      Header append Vary Accept-Encoding
    </FilesMatch>
</IfModule>
