Rendering nav meshes

I followed the guide in this thread

I am able to load the map up within gmod, but I am not able to load it in source sdk 2007. Whenever I attempt to load it I get the error of “ed_alloc no free edicts”.

When I googled “ed_alloc no free edicts” I found some stuff about how there is a source limit on entities within a map and was wondering if anyone knew how to get around this problem.

Why do you need to open in in Source SDK 2007?

Which goes back to my question of has anyone ever had to deal with “ed_alloc no free edicts”. I know that Garry’s Mod has a raised entity limit and was wondering if there was any way to raise it with source sdk 2007.
