After tons of researching, I found this post which explains that it’s more or less because it’s replicated and on net, the max render distance is 15,000 Units.
The Fix? I tried increasing the Cull Distance in the Blueprint by typing an absurdly high number. It defaulted to it’s original number -1. I manually slid the number higher and it gave me an even more absurd number.
It works. I don’t know if it’s the RIGHT way to do it. But it works. And it’s only for a couple Blueprints here and there. It doesn’t propagate across the entire game. So this “shouldn’t” cause lag.
