I have the full set of trees and plants from CGAxis in fbx format.
FluidImporterPro-4.0.11 cannot import any of them.
I get the error message on all tries of “Import Failed”. After that SketchUp is ‘frozen’: although the cursor is still active, nothing can be selected.
Using Autodesk FBX Comverter 2013.3, I converted some to obj and to dae but all failed to import using FluidImporterPro
I used SimLab Composer to re-save in SimLab’s fbx format and in obj format: they also failed to import using FluidImporterPro
All in all: Very disappointing
