[x3d-public] RawKee Normal Export Issue Fixed - WAS: Reallusion Character Creator - HAnim Example

[Michalis Kamburelis]

Data URI scheme ("data:...") is fully supported by Castle Game Engine
/ Castle Model Viewer. See
https://castle-engine.io/url#_embedded_data_data ,
https://en.wikipedia.org/wiki/Data_URI_scheme . It's a great way when
one needs to "embed" resources instead of linking to external files.

To be clear, this is something completely independent and with a
different purpose than "castle-data:" which is a specific invention of
Castle Game Engine to refer to project assets. See
https://castle-engine.io/url#_loading_data_files_castle_data ,
https://castle-engine.io/data . The similarity in the name is
unfortunate (but we don't have a better alternative, "castle-data"
makes a lot of sense for us, as this is kept in "data" subdirectory in
project usually...).

Bottom line: do not confuse "castle-data:" with "data:" :) Very
different things with different purposes. We happen to suport both in
Castle Game Engine / Castle Model Viewer. Only the latter ("data:") is
useful for stuff that should work in any X3D browser.

Michalis
