Hi Lee,
To start off, I recommend switching to using the
OpenSceneGraph format instead of WRL. OpenSceneGraph is Vizard's native model format, so it supports the widest gamut of features for models used in Vizard. The texture scale upon export should be much more reliable as well.
WRL, on the other hand, is a legacy format stored in plain text (loads slowly, can't embed images), and hasn't been updated in years.
