[Help] Making a weapon shine similar to TF2 sheens

I’ve been looking around but haven’t been able to find any tutorials anywhere so I’ve come to the forum to ask if anyone has a VR Chat-friendly way of doing something like this? Ideally the first thing that comes to mind that would make it a simpler task would be having a pulsing sheen like this but I’m not sure how to go about it, so I’m wondering if anyone has a method of doing so. Thanks!
