Well To be honest, I'm not sure why yours didnt work. The .x file you sent me had no bones or animations saved in it. It was just a sphere, and a segmented cylinder. That gave me the idea of what type of robot it was. So I took it upon myself to redo what you sent.
I use
Ultimate Unwrap3D to do all my UV mapping. It's the best I've yet to find IMO. It's not free, but it's worth every cent!
The model has no animations at all, just the bones needed for alignment, and the firespot designation. Check out the Milkshape file to see how the parts are assigned to the bones, and take note of the naming of the joints.
I used the settings above, with an animation range of 1-1(no frames between).
Check the .fpe out for additional values, and you can experiment with different AI scripts to get it to follow waypoints, chase you, etc.
The weapon is just a gun with an all black alpha channel in the D_2 texture to make it invisible.
Note: in some cases I've found that when doing these type of robots, that if you export "right Handed" the entity shoots backwards. if this happens, re-export with right handed unchecked.
