While working on re-creating sveral things from SWtor ( starting with one of my characters sabers) I noticed a problem when I try and render right now- even in it's WIP state

 

It's a pretty obvious issue, it's those blades that appear out of nowhere and I'me pretty sure may be tied to the reflection perhaps? if not any insight woule be wonderful, can't say I've ever run into this one before.

 

it also seems to do it regardless of the render settings as well
