It's important to understand the idea of C.X.. C.X. cannot bring your 3D models to the internet. Use the C4D built-in VRML exporter for that. C.X. is made to use CINEMA 4D as an editor for CSS animations to work in HTML5. So, since the result is written in HTML and CSS, only elements can be used, that are supported by this web language: boxes (=planes or nulls), text and images (=textures).
