Regarding .FBX exported model with animation not played in Vizard

[Veleno]

4)After exporting models from both 3Ds Max and Maya,why there is [empty] node with no name is viewed in INSPECTOR.

At the time of this post, all imported files display their structures as specified in the file, so the extra nodes appearing in the FBX file would have either been something that either existed in the source file or were put in place by the exporter for one reason or another.

Speaking generally, for the most reliable results and greatest amount of control we recommend exporting props and environments to Vizard's native format (OSGB) using our 3ds Max exporter using the attached preset file, with other options modified as needed. Once unzipped, the preset file can be loaded from the lower left dropdown menu in the export window (see attached image).

For skinned animation (i.e. characters), we recommend using our Cal3D exporter.
