3d - VRML export issue ArcScene

when I try to export simple Tins (or documents which contain Tins) from my ArcScene to .wrl the export fails. Please see my example:

I have the following table (xlsx):

X   Y   hoehe

28  -2  0
-2  -2  0
28  48  0
-2  48  0

I import it into ArcScene through add xy data. Than I build a Tin from it using hoehe as height field (There is no difference between using python or going manually):

arcpy.CreateTin_3d(r'C:\Users\aasen\Documents\ArcGIS\Default.gdb\floor_tin', '#',
'Tabelle1$ Events' hoehe Mass_Points ", 'DELAUNAY')

Doing this I get a nice flat Tin. Now I'm exporting the Tin with 3D -> VRML where I select the options:

Indent text [check]
visible layers [check]
GeoVRML [no check]
Center [no check]

ElevationGrid [check]
JPEG Quality = high

The resulting VRML (attached as unbenannt.rar) is incomplete. freeWRL is giving me the following error code:
