I'm hoping I can get some help off someone more intelligent than myself! I've posted this over on GarageGames also but thought I'd post here to reach a few more people.
I've had no problems creating terrains in L3DT Pro and exporting to atlas using the L3DT plugin with fairly small maps. However, after a couple of unsuccessful attempts at creating someting bigger I feel it is time to ask for assistance... I'm trying to export a terrain from l3dt (obviously) - the design map was set up as follows:
X=128
Y-128
Heightfield resolution = 2.00 (giving a resolution of 8192 x 8192)
Mosaic map checked, tile size = 512 (16x16 mosaic)
I have generated all the maps and for the time being at least, I haven't activated high-res maps (although I may want to at a later date). When I export using the L3DT plugin it gets to around 20% on 'Propogating Activation Levels' and then L3DT crashes.
So then I tried to do it using the console commands in TGEA. atlasOldGenerateChunkFileFromRaw16() seems to work, as well as importOldAtlasCHU(), so I then have my atlas geometry file. However, when I run atlasGenerateTextureTOCFromTiles() TGEA crashes on me. The console log doesn't really give me anything useful as I think it crashes before it has a chance to log anything:
- Code: Select all
atlasGenerateTextureTOCFromTiles - Initializing atlas file 'atlas.fps/data/terrains/testLargeTexture.atlas'...
AtlasDeferredFile::ensureStreamWritable - switching file into writable mode... This may cause a crash if you have other copies of Torque accessing it!
atlasGenerateTextureTOCFromTiles - Atlas started, processing tiles for 5 deep tree...
atlasGenerateTextureTOCFromTiles - Storing tiles in JPEG format...
Much of it is probably to do with me not understanding what all the variables mean on the various functions. For the above manual way of importing I used the following functions:
- Code: Select all
atlasOldGenerateChunkFileFromRaw16("atlas.fps/data/terrains/Maps/testLarge.raw", 8192, 2.0, 2.0/512.0, "atlas.fps/data/terrains/testLargeGeometry.chu", 1.0, 5);
Which gives me:
- Code: Select all

- done.
o Propagating activation levels...
- done.
o Writing file header...

Quite a few errors in there...?
I then used:
- Code: Select all
importOldAtlasCHU("atlas.fps/data/terrains/testLargeGeometry.chu", "atlas.fps/data/terrains/testLargeGeometry.atlas");
which gives no errors, and finally:
- Code: Select all
atlasGenerateTextureTOCFromTiles(16, "atlas.fps/data/terrains/Maps/TX/testLarge_TX_x%dy%d.jpg", "atlas.fps/data/terrains/testLargeTexture.atlas", 0);
If anyone could a) let me know if there is something obviously wrong with the above and b) explain what the variables in AtlasOldGenerateChunkFileFromRaw16() and atlasGenerateTextureTOCFromTiles() mean that would be great.
If you've got this far - thanks for reading!
