Hello Joe, you say it is a none realistic effect, what happens. I say you model is only a ‚test‘ model and a realistic model would have a more detailed texture and would always provide tex coords.

> Hi Holger, I certainly agree with this, but not during animation. We would use the default mapping once, for the default pose, then the same after animation begins. Again, the way it is showing is a neat effect, but not realistic, since the texture should stay mapped to the default pose, not recomputed at each frame.

However this feature is no longer working.  Am happy to correct it, or omit it, as appropriate.

> With version 6.0.0, X_ITE uses the new element name <x3d-canvas>, lowercase and with dash. Because X_ITE uses the Custom Element API from JavaScript now. This has the advantages that the element can be created with document.createElement, and is then immediately ready to use :). Other advantage is that the CSS file must not be included anymore.

> For compatibility the old name can still be used, but we encourage all users to update to the new tag name.
