Q3DM3D Duke3d map for Q3
just finished an old project to play the classic hollywood holocaust map from Duke Nukem in Quake 3
Video with a quick quicktour, gameplay and link to download + contributions in the description.
Replay if you try it and give us some feedback ![]()
Dude, I thought it would be more fun to play with bots than running around the map alone, so I tried generating an .aas file for bots. But you have a geometry problem. I've attached a detailed description below.
PROBLEM DESCRIPTION
Map: q3dn3d.bsp
ISSUE:
The map has a geometry leak. BSPC version 1.7 cannot generate an AAS file for maps with leaks because it cannot determine which areas are inside the map geometry and which are outside.
COMMAND USED:
bspc.exe -bsp2aas q3dn3d.bsp
SOLUTION - Fix the map leak
- Open the map in a map editor (NetRadiant, GtkRadiant, etc.)
- Find the leak point (where geometry is not sealed)
- Close the geometry by adding brushes to seal the leak
- Recompile the map
- Then generate AAS file
TECHNICAL DETAILS:
What is a map leak:
A map leak occurs when the map geometry is not completely sealed. There is a path from inside the map to the void (outside the map boundaries). BSPC needs a sealed map to determine which areas are walkable for bots.
Why AAS generation fails:
BSPC uses a flood fill algorithm to determine walkable areas. If there is a leak, the flood fill escapes to the void, making it impossible to determine the interior of the map. This is why the error "no entities inside" appears - the flood fill cannot find a sealed interior space.
Additional warnings:
- Duplicate planes in brushes 470, 490, 638, 640, 730
- Mirrored plane in brush 1204
- Bounds out of range in brushes 1204 and 1205 (coordinates exceed normal map limits)
These warnings may also contribute to the problem, but the leak is the primary issue preventing AAS generation.
ERROR MESSAGE:
ERROR: **** leaked ****
WARNING: no entities inside

Closed log bspc.logcool job, especially because the original Build Engine featured something like non eucledean Rooms, aka you can infinite teleport forward without leaving the grid. Basically you can build 2 rooms above each other with the same coordinates and depending on how you enter you are either in Room A or Room B.
PS: if i wanna play duke3d i just play the original.
Almost everything is good. It was there at the start, but then I got distracted and looked, and it evened out at another spawn.

I don't think it's a big deal. The map is nice, the bots run fast. Overall, I like it.
You can test it on any of these servers using the command:
/callvote map Q3DN3D
! RAIL-Box
! 007 Clan Arena
! 007 FFA FastRail
! 007 FFA RailNewDM17
! 007 1v1 Rail-DM17
! 007 CTF e5r
! 007 Rus Freeze Plus
! 007 Rus Rail Freeze
! 007 BFG-Speed
! 007 OPENBOXMEGARAIL
Do you use this tool - NetRadiant Grux?
There is one map that has the same geometry leak as you did - Coldrun.
But I'm a complete noob when it comes to using NetRadiant.
Bots seem to run fine in FFA, but when they split into teams (I played ! 007 Clan Arena), the bots on my team are incredibly slow. One of the four bots on the other team was also slow. I don't know the reason for this.
I think the map needs to be tested more in different modes
I don't have a .map file, but I think in any case, if I put in the effort and time, it can't fail.
and we may spawn in broken places/behind rooms
By the way, you can rewrite spawns in a simpler way. You can simply experiment with the .add file and the /viewpos command to view coordinates while you're in the game.




Cool... tks for the feedback.I fixed the leak and generated the .aas file.I released a new version with the file.
I've tested and the bots are ok now.

I would appreciate a new feedback
