I would suggest that users making their own models set up a template using a copy of a default FPSC model for scaling - even a single default FPSC wall will do for scaling, rotational and positioning purposes.
This should be set up in in Milkshape or another simple modeller known to be easily used and compatible with FPSC. Always ensure your model is placed on or just above above the centreline in Milkshape in the horizontal plane.
Use the .x file JT exporter to export your model from Milkshape.
Using this method you cant go far wrong. Using some other modeller types and methods of creation for preparation for output to .x for FPSC compatibility may leave you open to asking for unecessary problems which long term may become an increasing burden and cause much frustration which could easily be avoided.
Use whatever you like but if you want to make it easy for yourslef - use some tried and tested methods for development.
