Tools to convert Spring S3O models to OBJ format and back. Also, for baking Ambient Occlusion stuff.

optional arguments:
-h, --help show this help message and exit
-i INPUT, --input INPUT
The file to work on (s3o or obj)
-o OUTPUT, --output OUTPUT
The name of the output file. If not specified,
modification operations are done in-place
--s3otoobj Convert a file from s3o to obj
--wings3d Optimize smoothing groups for Wings3D OBJ output
--objtos3o Convert a file from obj to s3o
--transformuv TRANSFORMUV TRANSFORMUV TRANSFORMUV TRANSFORMUV
Transform UV space
--swaptex SWAPTEX SWAPTEX
Specify the two textures for s3o
--optimize Convert a file from obj to s3o
--printao print the AO information for an s3o
--clearao print the AO information for an s3o
--piecelist PIECELIST [PIECELIST ...]
Piece list to clear for --clearao, and piece list to
explode for --bakevertexao
--zerolevelao ZEROLEVELAO
Specify zero level for AO
--bakeaoplate Bake an AO plate for the model
--aoplatesizex AOPLATESIZEX
AO plate size X in footprint units
--aoplatesizez AOPLATESIZEZ
AO plate size Z in footprint units
--aoplateresolution AOPLATERESOLUTION
AO plate resolution in pixels
--xnormalpath XNORMALPATH
Path to xnormal.exe
--bakevertexao Bake vertex AO for the model
--isbuilding Vertex AO. Enable this when baking AO for buildings.
This puts a larger than normal groundplate underneath
the unit, to make sure the building is only lit from
the top hemisphere
--isflying Vertex AO. Use for aircraft, this remove the
groundplate from under the unit, so it can get lit
from all directions
--minclamp MINCLAMP Vertex AO. The darkest possible level AO shading will
go to. 0 means even the darkes is allowed, 255 means
that everything will be full white. 128 is good if you
dont want peices to go too dark.
--bias BIAS Vertex AO. Add this much to every vertex AO value,
positive values brighten, negative values darken. Sane
range [-255;255] .
--gain GAIN Vertex AO.Multiply calculated AO terms with this
value. A value of 2.0 would double the brightness of
each value, 0.5 would half it. AO_out = min(255,
max(clamp, AO_in * bias + gain)).
--merge merge all pieces in an s3o
--scale SCALE merge all pieces in an s3o
--recenter recalculate center, midpoint, height
--adds3o ADDS3O Take all the pieces of this file, and add it to the
root of input
--splits3o take the piecelist, and split that out into a new s3o
