Roll-lo Cores addon - Portal

Heya~ This is my newest modification to a model [kinda, since I had done this exact modification 3 or 2 years ago once before] - I thought they looked real interesting like this. Not that they weren't already interesting, but it's like a new look, you know~? I call them, Roll-lo Cores! [I can't think of anything else] - Why do I call them that? Well, from testing in-game, they literally roll around like a ball and don't stop.
They do eventually though, so no worries there~ That's pretty much all I got to say about this.

Stay safe~ <3
