When you posted there wasn't, but I've gotten Merl's permission to post modified copies of version 1.7 with MAX_MAP_PLANES set to 65535. Replace your build tools with these versions and you'll be able to compile bsps with over 32767 planes. Then use my optimizer (included in the zip files) to make them safe for the game again. I'm putting them into two zip files since they're over the 122880 byte max file limit in a single download.
To use my optimizer, you can drag and drop your bsp file over it. The program overwrites the original file, so make a backup if you want to preserve the unoptimized copy. **Note -- since this program shrinks the map, it will checksum differently -- if a server is running the unoptimized copy and you have the optimized, it might not let you connect **.
Once the map is optimized, HLCSG -onlyents and HLRAD will break (make the optimization the final step when you're compiling), but it will run fine in the game.
<span style='color:gray'>EDIT: If you get a 'file not found' error when running the tools, look at Ollj's post below, he has a solution to the problem. You can get the DLL he talks about <a href='http://www.cyscape.com/download/msvcr70.dll' target='_blank'>here</a>. If you still can't get the tools to run, two people have reported needing a second DLL you can grab from <a href='http://www.dll-files.com/dllindex/dll-files.shtml?msvcp70' target='_blank'>here</a>, but others seem to be OK without it.</span>
<span style='color:gray'>EDIT 2/4/03: updated opt_plns to version 1.2, fixing the crash on bsp file not found and fixing a rare case of corrupted data for the first plane on the map.</span>
<span style='color:gray'>EDIT 2/5/03: updated opt_plns (in first download) again to version 1.3, fixing a crash bug above 32K planes and adding an option (-nopause) to skip the keypress prompt at the end of execution. The updated opt_plns is available as a separate program on the 4th page of this thread. Unless another bug is found, this should be the last update for a while.</span>

<span style='color:gray'>EDIT 2/11/03: updated opt_plns again to version 1.4, removing internal limits on texdata, visdata, and lightdata. Also added a -logfile <filename> switch and made input filename parsing more forgiving.</span>

This DLL is needed by applications compiled to use the Microsoft
Foundation Classes (MFC) as a DLL, and compiled on a machine that has
the Microsoft .NET SDK installed on it. This is no different than older
MFC runtime DLL requirements; it's just that this is a very new runtime
DLL and most folks don't have it. The system running this application
(mapserver, compiled this way) also must have Microsoft Internet
Explorer 4.0 or higher installed on it, since the runtime uses
components from IE as well.

the map is half-completed (raw hallways) and already touches the 90% limit, because its BIG.
now its 50% and I hope the compression tool cuts enough planes from the void.
This is absolutely superb. I love you. <!--emo&:D--><img src='http://www.unknownworlds.com/forums/html/emoticons/biggrin.gif' border='0' valign='absmiddle' alt='biggrin.gif'><!--endemo-->
Now we may find out.
<!--emo&:0--><img src='http://www.unknownworlds.com/forums/html/emoticons/wow.gif' border='0' valign='absmiddle' alt='wow.gif'><!--endemo-->
So far it seems to work. A test map shrunk from 2080 planes to 484, and seems to run fine in-game.
Merl had bumped up the defined amount before, then knocked it back down when it caused in-game problems. This is a source comment embedded at the point of the directive:
<!--c1--></span><table border='0' align='center' width='95%' cellpadding='3' cellspacing='1'><tr><td><b>CODE</b> </td></tr><tr><td id='CODE'><!--ec1-->#define MAX_MAP_PLANES 32767
// (from email): I have been building a rather complicated map, and using your latest
// tools (1.61) it seemed to compile fine. However, in game, the engine was dropping
// a lot of faces from almost every FUNC_WALL, and also caused a strange texture
// phenomenon in software mode (see attached screen shot). When I compiled with v1.41,
// I noticed that it hit the MAX_MAP_PLANES limit of 32k. After deleting some brushes
// I was able to bring the map under the limit, and all of the previous errors went away.<!--c2--></td></tr></table><span class='postcolor'><!--ec2-->
The problem has always been game engine based rather than something with the compiler. I suspect that the half-life engine uses a 32K sized static array for storing the loaded planes, and loses information when this is exceeded. There isn't anything magic about the 32K plane limit (it's not a hardware concern like the 4MB texture limit, for instance), and I'm willing to bet it was a semi-arbitrary size placed by the programmers when 400 was considered a high r_speeds value (akin to "nobody will ever need over 640K of memory" <!--emo&:)--><img src='http://www.unknownworlds.com/forums/html/emoticons/smile.gif' border='0' valign='absmiddle' alt='smile.gif'><!--endemo--> ).
i can even detail my map further now... god i wub j00
In my experience, if the map has too many planes in it then you can't fully compile the map anyway. If you've removed this 'lock', then kudos to you and congratulations on producing such a useful tool. But, if you still can't compile maps which originally have too many planes (before the optimisation), then that makes this kinda useless.
Yep, it's been moved up to about double what it was before (65535 now). If that's still not high enough, another recompile can shift it upwards again... the only limitation for the compiler tools (I'm <i>not</i> talking about running the game itself here) is the amount of memory required to store the information while it's being processed.
EDIT: shifting the limit upward again will require storing the information outside of the bsp during the compile because the bsp face structure's plane number field can only hold 16 bits.
Damn straight! <!--emo&:p--><img src='http://www.unknownworlds.com/forums/html/emoticons/tounge.gif' border='0' style='vertical-align:middle' alt='tounge.gif'><!--endemo-->

The only thing I would like added to that thread is a mention of the optimizer -- if you forget to use it and you're over the old planes limit, the map still breaks in the game... running the optimizer is really what allows the new flexibility-- ZHLT has had the higher limit before, and I don't want to cause any confusion. The extra program (opt_plns.exe) isn't part of the official tools, but I've submitted the source to Merl for inclusion in future builds.

Average amount reduced: ~63%
Minimum amount reduced: ~59%
Maximum amount reduced: ~66%
Based on this, I'm seeing just shy of a 2/3rds reduction in the larger maps. Note that Hera and Eclipse, two of the maps that ran into the most problems in development as I recall, and likely had the most plane-optimization done to them already, benefited the most from the optimizer, while Caged didn't break 60% benefit, unlike all other maps in the test-set.
So, to be able to truly 'unlock' the abilities of higher plane-counts, I'd recommend supporting enough planes that in real-world work, even with the optimizer, it's possible to end up with too many planes. This may sound counter-productive, but right now you're possibly artificially-limiting the planes available now, with how effecient the optimizer actually is.
Also, this is a good example of just how much of a reduction this one tool is actually able to make in-game.
