Water Tight Tool

Building submarines in Garry’s Mod has always been fun. I’ve made crazy under water vehicles in the past few years that I’ve been playing. However, I find it very annoying that the submarines technically don’t work. When you put them underwater, they just fill with water. This makes it hard to walk around inside the submarine while it’s submerged. I’ve been wondering why no one has made a tool to counter act this problem. I know it would be difficult to make a tool which makes props water proof, but I have one question. Is it possible?

I don’t think that it’s possible with the current engine. Source’s water effects are pretty limited.

Dynamic water is far out of the reach of Source’s capabilities.
You could create a script that removes the overlay or maybe revert the gravity to dry land, but actually making a sub waterproof is impossible.

Yeah that would hinder it’s creation. Oh well, thanks anyway!

Yeah, impossible with current source engine.
However, Life support can get really close to this.
You can breathe in the submarine, and have normal gravity in it.
but still, you could see the water in your submarine.
