Luxinia F3D? Model Toolkit (downloadable in the Download section)
Extract files into the plugins directory of c4d (can be placed in subdirectory)
There are three new export options, if the installation was successful (check console otherwise and report bugs if errors are shown exist).
MM Export: Hardly used ASCII export format that can be read by Luxinia
F3D? Export: Used for exporting the currently selected object, which must be a meshmodel
F3D? Group Export: Select an object that has child objects that are made of meshmodels. It will then export all of them as distinct modelfiles with the name of the object - useful if lots of objects are needed to be exported.
Also, a new plugin is available named ppcount - it will count the (real) triangles and points of the selected meshobject and reports them. The reported number of triangles/points is identical to the used triangles in Luxinia for the object.
