You have 2 options:
1. You can create _ori file from _sp file - if You really want to, but _ori is only useful on planes where You want to use alpha blending for textures. Sometimes gloves and boot's are simple cylindrical shape, so there is no need for _ori.
2. If You have only _sp file, use it as Diffuse and SpecularityMask. Thats all.

Edit Your env.ini - the Num= should be much highier for this effect. Remember it will effect all of Your enchanted weapons. You don't see this on Your video, because author focused on one weapons. You will see it by Yourself. Unless, You change the Num= size ONLY for 65535 (last enchant) which will be available only for admin

Also, You can remain the effetc simply by changing the is_hero option to 1.

Have fun
