If you want your own Nav Mesh and specially for this beautiful piece of art. First lower your graphics all the way, lower your screen res to the smallest resolution.


JUST DO IT DAMN YOU.

Follow the instructions in the Navmesh descriptions or find a tutorial, which I have below this.

Turn on SV_Cheats 1 in (~ Key) console, put Walkable nodes in various zones of the map, from wide open walk-to-freely areas to if needed to places no one will ever bother being, a pink pyramid looking wireframe that you can spawn with the tool in the Q menu on the far right, search for Nav if you cannot find this tool, this will make the nav mesh generate appropriately to areas people will most likely want to mess around in, then put in nav_max_view_distance 2000 in (~ key) console to speed up the process.

After clicking generate map, please do the following and let the game generate a new nav mesh by LEAVING THE GAME WINDOW, go work on something else while it does the thing, GPU Saver & Lower Graphics & Screen Resolution will let the job go by faster, you have been ultimately, and literally, warned, since no good machine can make this game run any better.

Powerful Machines will however maybe I don't really know make it generate faster, lesser machines might encounter issues.

Be also warned that if the map is without a doubt complex and full of walls and platforms, watchamacallits and hoozits, you will be waiting for the chef to get done baking that bad boy.

When it's done you can edit the nav mesh manually, again, follow a tutorial or test it yourself, nothing will crash so don't be afraid, and be sure to have Nextbots and Left 4 Dead NPCs, with God Mode on, to do some fancy testing (no source needed for the left 4 dead) to test everything if needed.

When you are done editing ANYTHING at all with a visible number ID that pops up, compress the IDs in the nav mesh tool in Q menu, you M U S T compress the IDs first, then save.

If nothing seems right, drag and drop the Nav Mesh file in the Maps folder, to Desktop to keep if the new edit doesn't work right, then edit around anything standing out in your current Gmod session, then save again and it will generate a new nav mesh file, rinse and repeat until you are done!

SAVING THE GAME DOES NOT SAVE THE NAV MESH, SAVE THE NAV MESH WITHIN THE TOOL!!!

Making nav mesh is fun!

Some stuff does not save, or works correctly online which I have no idea, I do not know how to fix this. maybe upload the file to the workshop or a friend, or find one and subscribe?

Have fun!
