Hello Josh,

Titania does not handle X3D XML Encoded files directly. To load *.x3d files Titania needs the small helper program x3d2vrml, which does the conversion. The tool folder is directly located in the Titania project folder. The tool must be installed properly, and must be in the search path, that Titania can found it.

For instance copy the contents of x3d2vrml/bin to /usr/local/bin and the contents of x3d2vrml/share to /usr/local/share.

Sorry but the make file isn't yet made for such purpose.

If you can load the deer you will recognice that it looks not properly. To do so toggle the vertex ordering (ccw).

I can load the deer now, Thanks.

I am still a newbie at this program, so I am trying to figure the whole thing out and the possibilities.
aka how to "Toggle the vertex ordering (ccw)."

on a side note, I do have a vrml from Pro Engineer that isn't parsing, can I some how attach the file here, or in a bug maybe.

You can write a bug report and attach a file there.

Added Makefile.am to x3dtidy and added install-exec-hock to libtitania-x3d, Titania, and x3dtidy to install required files to share directory and bin.

x3dtidy should now install out of the box.
