Blender's .x file
is problematic. I use Blender for all of my modeling inside and outside of FPS Creator. What I ended up doing to get my models into FPSC from Blender was buy Milkshape to transfer the OBJ file from Blender into Milkshape, and export them from there as a .x file. It works fine this way, and retains the texture.
I don't use Milkshape for anything else other than exporting. It's very limited and time consuming compared to what can be done with Blender. But it works fine for getting Blender-made models into FPS Creator.
