"map has no node"

[Hugo]

Does anyone knows how to fix that?

Gtk after compile launch URT but it shows this message and I can't help it so far.

First: the correct error message is “map has no nodes” (verbatim error messages make searching way easier, I had to grep the game binary for “node” to figure out why Google wasn’t returning any hits).

The interwebs have various possible explanations how this could happen and no clean and simple answer, but the underlying reason is that the BSP volume has not been created during compile (“no nodes”), i.e. something in the map construction is preventing the compiler from interpreting the structural brushes correctly and the map has no “inside”. Look for brush entities that shouldn’t be there — the most likely way this could happen is that you have accidentally selected the whole map and turned it into an entity, making the worldspawn empty. Press L to see the entity list (also found in the View menu) and take a look at the bottom of the list to see if the worldspawn contains any brushes. To fix this, select the bad brushes and do Entity → Ungroup.

If this doesn’t help, upload the .MAP file and I’ll take a look.

you could also try running a brush/ent cleanup.

anyway, as it might be that your map leaked but the compiler didnt noticed (an outer brush isnt structural and worldspawn)
as suggested here

for testing ONLY you could try buulding a big box around everything, make it structural and worldspawn (it should be by default)
