Sorry. You just need to open the txi file with a text editor, where is written "envmaptexture CM_Baremetal" add below "umpyshinytexture CM_goto", then below that "bumpmaptexture P_GtB", then below that "clamp 3", and then below that "xbox".It should be like this:
envmaptexture CM_Baremetal
umpyshinytexture CM_goto
bumpmaptexture P_GtB
clamp 3
xbox
