Any chance you could try exporting a couple of TAQFH models out of AC3d in 
VRML format to give me some more fodder for the parser?

Nor am I - that file is a little nasty in terms of having empty nodes or 
nodes with default values.  If AC3D is expecting valid contents for VRML 
nodes in its loader, I'm not surprised it had trouble.  That test file came 
from the original VRML1.0 parser/loader produced by SGI back in 1995, and I 
suspect that it was only really intended to show that parser could 
recognise all of the nodes.

I'll be producing a full set of new VRML1 test files for the parser, so 
hopefully they should provide a fairer test once they're done.  Since these 
won't really form part of the PLIB distribution but would be useful to have 
around, where should I put them?  Is there a convenient place in the CVS 
tree for them, or would they be better just on my local web site?

Rgds,
