First of all, no: Im not telling the creator to make a mesh HIMSELF, there is nav_generate.

Now, if you downloaded this map and copied & pasted it to your maps folder, you may want to play with someone but there is no servers running this map, so, you would need a NAV mesh to play with bots right? the problem is that your game's FPS will drop extremly while the mesh is being created, but the wait is really short, but for you, do you think making a NAV mesh is worth it for this map? is it enough fun to play for you to make the mesh? for me, it is, (i made a NAV mesh) please post your opinión about this.
