<p class="MsoNormal">John, we have a lot of simple prototypes
and prototypes with embedded Script nodes in the archives
that have all tested OK.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">If your example is that Rubiks’s cube
with nested prototypes, that is harder. We believe the spec
is OK but that feature is only occasionally demonstrated as
working. Any model with nested prototypes (ProtoDeclare
within ProtoDeclare) can be easily refactored by putting all
of the ProtoDeclare blocks first. Similarly it makes sense
to test individual ProtoInstance nodes without feeding them
nested ProtoInstance fields.<o:p></o:p></p>

If you don’t want to run my code, convert your own

<p class="MsoNormal">The main purpose is to get proper
implementation of Protos in pure python. I’m
guessing it may be a wider problem with x3d.py,
because when I patched Protos in my version, there
were further issues. So simply patching Protos won’t
fix all the issues. A full roundtrip XML ->
python -> XML needs to be done for the archive.<o:p></o:p></p>

python, and I plan to start work on a test suite soon.
It would be good to get past my initial issues with
the package. I can reattempt to modify the x3d
package generator, but that doesn’t mean my patches
will be available when I am done. It still needs to
go through official channels.<o:p></o:p></p>
