Game crashed with huge atlas terrain texture

OK. I have a 1025X1025 height map (generated using L3DT). I can successfully generate a chu file using this command:
generateChunkFileFromRaw16("MyDemo/data/terrains/terrain1.raw", 1024, 2.0, 1.0 / 256.0, "MyDemo/data/terrains/terrain1.chu", 2, 2);
My terrain1_TX.jpg file is 12288X12288 (27MB). When I use this command TSE crashes:
generateTQT("MyDemo/data/terrains/terrain1_TX.jpg", "MyDemo/data/terrains/terrain1.tqt", 2, 6144);
If I crank the chu treedepth to 5 and the tqt depth to 5 it generates a tqt file. However, TSE still crashes when loading the mission. Here is the last few lines of the console:
*** Phase 3: Mission Lighting
Mission lighting done
Mapping string: MissionStartPhase3Ack to index: 2
Mapping string: MissionStart to index: 11
Mapping string: SyncClock to index: 12
*** Initial Control Object
Activating DirectInput...
When it crashes I can see the terrain in white without texture for a second. I dont know whats wrong. I haven't reached the 65K limit. I tried messing with the error/tree and still no go. I am using the MS3 head that I downloaded a few days ago. This will not work in my MS2 version of TSE either.

The height map should always be one more than the original size of the map. This is in the atlas documentation.

Each time I tried to create a tqt greater than 8192x8192, it crashes. I think Engine can't handle more than 8192x8192.

My PC has plenty of memory too. 2GB XMS.

Vincent, I'm glad you said that because I noticed that too. I just wanted to make sure I wasn't doing anything wrong. The documentation says it can handle 65K X 65K and I can never get anything higher than 8192 either.My PC has plenty of memory too. 2GB XMS.

It seems that libjpeg can't handle more than 8192x8192 even if theorical limit for jpeg is 65Kx65K :(. I saw in TSE code that Ben think to merge TQT files, it could be a solution to this problem. FTM I have no solution about this issue.

It DEFINITELY won't work until you fix that issue.

12288X12288 is not a valid texture size. You must have power of 2 sizes. I mentioned this in IM conversation with you earlier. :)It DEFINITELY won't work until you fix that issue.
