Every once in a while, after modifying my 3do's,
they all render fully lit. Sometimes they even
crash the game after they have been resaved.
I have corrected the problem before by randomly
resaving the files and messing with all sorts of
flags and value changes. I have looked at the
extralight values on everything and they are all
zero. I can't find any logical reason why they
are still fully lit. Has anyone else had this problem?
Any solutions? I am sick of wasting two hours
trying to fix my lighting everytime I change one
texture or something else little like that.

Do you reload and resave your templates? Even changing a texture can fuggle them up.

well theres that, but it also sounds like he's using JOKE.

JOKE always exports a 3do with extralight set at 1.

and 90%, if you export a 3do from JOKE straight into game, it wont work.

before using the 3do, open in JED, set extralight to 0, and export again as 3do from JED.

and if that doesnt work, GOd officially hates you, and doesnt want you to edit JK, so you should give up :p

if(getThingFlags(source) & 0x8){
  do her}
elseif(getThingFlags(source) & 0x4){
  do other babe}
else{
  do a dude}

I don't think god can hate. Or wait, he's almighty, so he probably can. But why should he? I mean, if he really hated something, then surely it would not last any moment longer. Hate => destruction.

I have been using Joke. That must be my
problem. I have done everything said. I
just have to play the resaving game untill
it spontaneously ends up the way it's
supposed to look.

My suspicion, though I haven't done the research/testing, is that Joke exports 3dos that can go over some resource limit.

I'm thinking texture vertices, because Joke exports duplicate vertices where jed does not.

Meaning, if you have 20 vertices of '0 0', 10 of '1 0' 10 of '0 1' and 5 of '1 1', joke will create a 3do with 45 texture vertices. When exported from Jed, you will have 4, because it does not print out duplicates. On higher-poly models, the texture vertex count will be much higher, thus, commonly causing great numbers of texture vertices (breaking the limit, possibly)

I have looked into it a bit more
and am quite sure it is something
with the sector that makes this an
issue. I think I can correct the
problem by going into my backup
copies and copying my sector into
my new map. It still makes no
sense as to what the problem is
though since my sector values are
not different. I think it is a saving
issue here.

JOKE is a good program. If you open your 3do in notepad/wordpad, you can see all the information about 3do pieces, verticies, textures, and surfaces. You will probably come across something like this in each part section:

0: 1 0x0 4 3 1 1 ............
1: 1 0x0 4 3 1 1 ............

where the first number is the face number, the second refers to the texture of that face (listed on top) and the fourth number of 4 3 1 1 is extra light. Change this to something like

0: 1 0x0 4 3 1 0 ............
1: 1 0x0 4 3 1 0 ............ to be not extra lit

in Wordpad you can use the "replace"

replace
"0x0 4 3 1 1"
with
"0x0 4 3 1 0"

notepad has that function as well. Or at least in WinXp, don't know about older versions.
