If I own a game that displays textures on my server map, does everyone need that game?

I am thinking about starting a DarkRP server on a map called RP_Uptown_V1. However it does require DoD to display some textures. If I used this map on a DarkRP server, would everyone need the game to see the textures on the map, or would I only.

Really new to GMod server hosting, any advice would be appreciated. Thanks!

Everyone would need it.

Download a program called Pakrat, which allows you to compress textures directly into the map, meaning even if players don’t have the game, they can still see it.

You can find the DOD textures by downloading the game yourself or nicking them from someone’s fastDL, either work.
