Converting an AIN File into BSP

So I’ve heard the only way to set a default server map is if its a .BSP file I currently have rp_stardestroyer_b4 download but it downloads as a .AIN I have upload it to gmod>maps>graphs does anyone know if there is a way to set it as your default map?

.ain files are AI Node graph information files. They’re just extra information for standard NPCs. None of the map geometry, entities, or anything of the like is stored inside. You’re going to need to get yourself the actual .bsp file, which is available on the workshop.

Nvm I found it as a .GMA file I guess Ill just convert it.
