[x3d-public] rendering issue for expanded prototype results (not related I hope), Cobweb vs X3DOM

Sun Jul 3 14:53:06 PDT 2016

The new downloads allowed me to test examples/Vrml2.0Sourcebook/Chapter31-Prototypes/Figure31.5/WoodAppearanceExternalPrototypes.json in the prototype expander.

This file renders differently in X3DOM versus Cobweb in my X3D XML Loader.  Cobweb renders in brown, and X3DOM renders in grey.  I do not think it’s prototype
Expander related, but it could be an error in the file or the way the different browsers handle diffuseColor and ImageTexture.  It could be an error in my loader as well (empty()).

Worthy of further investigation and running different versions through X3D-Edit.
