Don,

I just tried the validator on flowers2.x3d, and got the following:

<Script DEF='OrbitScript'> <field name='g' accessType='outputOnly'/> cannot define function g() unless accessType is inputOnly or inputOutput[/X3D/Scene/Group/ProtoDeclare/ProtoBody/Group/Script/field[6], error] <ProtoInstance name='orbit' DEF=''> <fieldValue name='translation' value='-8 0 0'/> with defined type='SFVec3f' accessType='inputOutput' has default value and is optional [/X3D/Scene/Group/ProtoInstance[1]/fieldValue[1], hint] <ProtoInstance name='orbit' DEF=''> <fieldValue name='diffuseColor' value='1 0.5 0'/> with defined type='SFColor' accessType='inputOutput' has default value and is optional [/X3D/Scene/Group/ProtoInstance[1]/fieldValue[2], hint] <ProtoInstance name='orbit' DEF=''> <fieldValue name='specularColor' value='1 0.5 0'/> with defined type='SFColor' accessType='inputOutput' has default value and is optional [/X3D/Scene/Group/ProtoInstance[1]/fieldValue[3], hint] <ProtoInstance name='orbit' DEF=''> <fieldValue name='transparency' value='0.75'/> with defined type='SFFloat' accessType='inputOutput' has default value and is optional [/X3D/Scene/Group/ProtoInstance[1]/fieldValue[4], hint] Error(s) detected during this validation test. X3D Schematron check: fail. Good practice is to fix errors and warnings wherever possible, and consider silencing harmless informational messages, so that important indicators remain noticeable.

The error that appears seems strange.  g is an output variable from my script. I could make it inputOutput, but that’s confusing.

Flowers2.x3d and Flowers2.json are attached.

The validation error shown is on flowers.json, so I’m suspecting some problem in the ProtoExpander for X3DOM.  No validation error shows on index.html for flowers.json with proto expansion on.  Hmm.  Hmm. Prototypes.html uses the dev distribution version of x3dom while index.html uses my version.  The proto expanders are somewhat different between the two.  Hmm. Hmm.

Flowers.x3d and flowers.json are attached.
Guess I’ll have to sleep on it or something.

I am feeling the main problem may be with coordIndex in flowers2.x3d, since it doesn’t display with X_ITE in index.html

I totally agree that the coordIndex problem is mine.

Thanks,

John

(First: original posts were extremely large... please use links for big things like that next time.)

John, here are several suggestions.

Have you tried X3D Validator on XML form of your model yet?

	X3D Validator
	https://savage.nps.edu/X3dValidator

X3D Tooltips have lots of information too.

	X3D Tooltips: IndexedFaceSet
	https://www.web3d.org/x3d/tooltips/X3dTooltips.html#IndexedFaceSet

X3DJSAIL can help with conversion if needed (though still needs .json import), also has internal validation complementing X3D Validator:

	X3D Java Scene Access Interface Library (X3DJSAIL)
	https://www.web3d.org/specifications/java/X3DJSAIL.html

IFS is perhaps the most common and long-running node so need for a specification change is quite unlikely.

"Divide and conquer" is a good way to debug issues.  Suggest you work on individual pages before smashups.  It is also popping up an error console, but the text is not copyable, so screenshot attached.

You can find a few thousand examples using X_ITE in the X3D Example Archives, if you think the conversion patterns can be improved then am happy to apply changes.

	X3D Resources, Examples: Scene Archives for X3D
	https://www.web3d.org/x3d/content/examples/X3dResources.html#Examples

	https://www.web3d.org/x3d/content/examples/HelloWorldX_ITE.html

Echoing: good luck.
