Hi Tereith,
For a detailed explanation of what steps to take for importing .x files into FPSC-R there is a PDF guide already included in the Reloaded folder.
This is the path on my PC:
"C:\Program Files (x86)\The Game Creators\FPS Creator Reloaded\Docs\Importing models into FPS Creator Reloaded.pdf"
It's still a bit convoluted at the moment but hopefully the Model Importer and/or the Construction Kit will make the process easier
Slainte!
