Are the SE weather effects contained in the KMOD 4 code? If yes, how do I add them to a map?

1) yes 2) krpg.acs is the file you should import in map scripts, it contains definitions to weather actions:

            1200:Env_WeatherSnow(5),			  // density (default = 120), horz angle, horz speed x8, vert speed x8, pattern
            1201:Env_WeatherRain(5),			  // density (default = 40), horz angle, horz speed x8, vert speed x8, pattern
            1202:Env_WeatherTerminate(1),         // weather num
            1203:Env_WeatherTerminateAll(0),
            1204:Env_WeatherSetParams(5),         // weather num, density, horz angle, horz speed x8, vert speed x8
            1205:Env_WeatherSetPattern(2),        // weather num, pattern
            1206:Env_WeatherSetColour(5);         // weather num, red, green, blue, alpha

patterns are

#define env_pattern_none			0
#define env_pattern_rainlight		1
#define env_pattern_rainmoderate                2
#define env_pattern_rainheavy		3

Now when you mention this though I remember there was some problem related to compiling scripts via DoomBuilder2 using our custom acc compiler; it was like DB2 sent some extra parameter that compiler couldn't handle. And custom compiler is needed to use ACS commands with id >255... If that will be a problem, you may try using DB1 instead.... that's an ugly solution though. If I'll have time I'll try to make a new custom compiler based on latest version.

DB2 also doesn't display the scripts included in a map at all, I recall you having suggested a workaround for that, it was something about opening the map in another editor and doing something to the scripts and then saving again, after which they would show up in DB2, but I am not quite sure how exactly it goes.

RambOrc, I am having troublesome times IRL at the moment. When it's finally over, I'll come back and try to find a decent solution to these issues. Perhaps after couple of weeks or so.

No hurry, good luck solving your troubles.

That took longer than I've expected <!-- s:x --><img src="{SMILIES_PATH}/orc8.gif" alt=":x" title="Mad" /><!-- s:x --> I am planning on getting latest acc compiler sources (the one that is compatible with DB2) and making sure compiler suits our needs.
