or you could do what i told you would work in the other thread.
to quote myself,
but to answer your question, you'll have to move one of Olimar's antenna bones. open up BrawlBox, then find his antenna bones (he's got 5, i think). then click one of them (shouldn't matter which, but the last one called AntennaAttacheN is the one the glow attaches to) and move it's X Translation a very large number up (like 1000 or so). then it should be gone in game. if not, then move one of the other antenna bones. and make sure you're editing the t-pose, not an animation, that way it will affect all the animations.
