How to make projectiles disappear when hitting a certain surface?

[Dzemorek]

You know, just like they do on rocket jumping maps.

Tried searching for the answer for over an hour and couldn't find it anywhere, tried to download rocket jump maps too and see in hammer how they did that but every single one i downloaded was in a file that you couldn't put into hammer.

Never wondered what happens to your .vmf file after you compile it? A compiled map is saved as .bsp file which can be used by the game. To look in hammer how this map is build, you have to download a software to decompile the map back to its .vmf format.

Now, to actually answer the question: they put a thin layer of func_nogrenades on the surface.
