Reality Factory

i'm using google sketchup to create models.i want to export some of my models into reality factory but i don't have any plugin or i don't know in which format i should export my model to use in reality factory. Somewhere i have read that .act format is can be used but i don't know it is for actor or environment (buildings etc.)................................... ...........................HC

RF uses the .act format for all models and meshes. Equity is a tool that can be used for converting model formats to .act format and do many other things also. Equity will import .obj .3ds and other formats. Read the manual and download the free e-book and all is explained in those on how to build a game.
