Need to make a warp drive effect like the one on SSB Final Destination please help?

so if you have ever played the final destination map for gmod then there is a part where its like warp drive. I askded the creator on how to make it so he gave me a prefab of it. there are two diamond shaped objects inside each other and they spin. they have the no draw texture on it. Since i am still a noob at hammer editor i have no idea what this means but maybe you could help elaborate. here is the prefab
not sure if he deleted it yet though.

If there’s no entities it sounds like he’s using the HoM effect intentionally
