Blocking VIS on displacements

[Spike]

Hello, I have a beach completed with cliffs and tunnels inside, so now I have to optimize all, and I think best way to block VIS on displacements is putting solid blocks inside them. I'm asking if is there another way to do it better, or is there an especific entity to do this?

Just NODRAW brushes where you want the VIS blocked.

Won't them create leaks?

Nope, displacements don't seal, so you need a regular brush behind them to do that. Brushes textured with NODRAW seal just like any other brush, but obviously are more efficient to render (or not render, depending on how you look at it).
