Hello Pascuale,
We got following issue as we try to set up a client connecting to 
Webtundra Server.
We got WebTundra Server from here: https://github.com/realXtend/WebTundra
Following instructions:
*Running locally *
 1. Acquire a realXtend Tundra <https://github.com/realXtend/tundra>
    server build that has |WebSocketServerModule|.
 2. Run the server with |TundraConsole.exe --server --headless
    --nullrenderer --file x.txml|.
      * Make sure |WebSocketServerModule| is loaded by the config
        (default server config should do this)
      * You can use any .txml as the scene.
 3. Open up the |html/client.html| in your browser (latest Chrome,
    Firefox or Opera is recommended).
      * If you are not hosting the WebTundra folder on a local web
        server (recommended), you need to allow local files so the local
        scripts load succesfully eg. in Chrome add command parameter
        |--allow-file-access-from-files|.
 4. Connect to the server with Connect button.
 5. You are done. Start developing your application.
      * Use the browsers developer tools to see errors and other logging
        (|Ctrl+Shift+i| in Chrome)
  First step was succesful completed as we installed syncer.
http://catalogue.fiware.org/enablers/synchronization
https://forge.fiware.org/frs/download.php/1702/Synchronization-Server-2.5.4-Windows-x64.exe
Second step was to execute tundreconsole using a demo scene bundled 
within server.
tundraconsole --server --headless --nullrenderer --opengl --file 
scenes/assimpdemo/scene.txml
This is the log. Last line informs us connection was done.

Third step was accomplished connecting by Chrome Browser with param 
|--allow-file-access-from-files|.
Fourth step. Connecting with Tundra Client.

Fifth step. Inspecting with Developer Tools. Objects look like to be 
here but they are not visible.
Using a "regular" Tundra Client we _are able_ to see objects.
Is known any issue in using Webtundra client so objects are not shown?
Best Regards.
