It dosnt lag for me at all.
Its suppose to look like if its rocky, not a flat surface
Do u have any suggestions on making a rocky wall then?
You're the host... unless your PC sucks then of course you're not going to lag. But that doesn't mean nobody else will lag, and you're gonna host a DM. Keep that in mind. Dms have a lot of projectiles that lag.
I understand it is supposed to look rocky, but its too duped. Ramps like that also look really weird when your wall is perfectly straight, try angling it or using a Brick Terrain style.
