I would like to use FME as a 3d model converter/processor. We know that the 3D Clipper of FME is not being supported yet and I would like to split the osgb model with z values using https://www.openscenegraph.com/ such as using this example code https://github.com/openscenegraph/OpenSceneGraph/blob/master/examples/osgclip/osgclip.cpp#L109 . However, I find that the osgt file cannot be recognized by FME and the following error messages are shown:
OSG Reader: Ignoring unsupported node
OSG Reader: Ignoring unsupported geometry - only surfaces are supported
How I can generate a cropped 3d model that can be opened by FME? Any suggestions are welcome! Thank you.
