Yes, the gem gives off the light & can be customized to be different colors, bcos it uses the ID under the Light tab in the WorldObjects tab in CS. Every ground mesh you choose to be the mesh for the light ID, will produce light. & it doesn't need a script! :thumbsup: Mmmm...i ever tried to add the gem to the mesh in NifSkope, but since the right hand weapon is recognized by Oblivion engine as weapon, it doesn't produce light, even there's a gem mesh added to the weapon. My offhand-lightsaber uses an armor ID, shield mesh with lightsaber model & lightsaber weapon ID for the ground mesh...& it auto-equipped when you unsheath a right-hand weapon (using script from Shield on Back mod). But...since the ID i use for the offhand-lightsaber is armor/clothing (i.e: amulet, ring) ID, it didn't produce light... :( To produce light, always have to use light ID. But light ID can't be used as shield, so what's the use of offhand-lightsaber? So, i think the 1st idea is impossible (i hate so say that!).... About the 2nd idea, i think a lightsaber author known as heavywaters is working on with that idea...I still don't know how it works, but it's possibly possible... :sweat:
