Hello SAAB Driver,
Quote: "In order to convert x.files into .fbx files i use the XSI mod tool, but the x.files texture wont import, leaving me a wihte mesh. Does anyone know how to get the texture imported aswell into XSI mod tool?"
Unity can read in addition to .FBX, also .dae (Collada), .3DS, .dxf and .obj files though.
You might try to convert FPSC models (.X files) to .3DS or .OBJ files with Fragmotion or Milkshape as well instead using .FBX files.
Maybe your .FBX files are correct but you are not loading your mesh textures in the right place at Unity.
Perhaps Unity forum guys may help you better than me.
Good luck!
