__bpydoc__ = """This script is a Blender => Cal3D converter.
|
|
(See http://blender.org and http://cal3d.sourceforge.net)
|
|
|
|
USAGE
|
|
|
|
To install it, place the script in your $HOME/.blender/scripts directory.
|
|
Then open the File->Export->Cal3d menu. And select the filename of the .cfg file.
|
|
The exporter will create a set of other files with same prefix (ie. bla.cfg, bla.xsf,
|
|
bla_Action1.xaf, bla_Action2.xaf, ...).
|
|
You should be able to open the .cfg file in cal3d_miniviewer.
|
|
|
|
|
|
NOT (YET) SUPPORTED
|
|
|
|
- Rotation, translation, or stretching Blender objects is still quite
|
|
buggy, so AVOID MOVING / ROTATING / RESIZE OBJECTS (either mesh or armature) !
|
|
Instead, edit the object (with tab), select all points / bones (with "a"),
|
|
and move / rotate / resize them.
|
|
- no support for exporting springs yet
|
|
- no support for exporting material colors (most games should only use images
|
|
I think...)
|
|
|
|
|
|
KNOWN ISSUES
|
|
|
|
- Cal3D versions <=0.9.1 have a bug where animations aren't played when the root bone
|
|
is not animated
|
|
- Cal3D versions <=0.9.1 have a bug where objects that aren't influenced by any bones
|
|
are not drawn (fixed in Cal3D CVS)
|
|
|
|
|
|
NOTES
|
|
|
|
It requires a very recent version of Blender (tested with 2.41).
|
|
|
|
Build a model follows a few rules:
|
|
- Use only a single armature
|
|
- Use only a single rootbone (Cal3D doesn't support floating bones)
|
|
- Use only locrot keys (Cal3D doesn't support bone's size change)
|
|
- Don't try to create child/parent constructs in blender object, that gets exported
|
|
incorrectly at the moment
|
|
- Objects or animations whose names start by "_" are not exported (hidden object)
|
|
|
|
It can be run in batch mode, as following :
|
|
blender model.blend -P blender2cal3d.py --blender2cal3d FILENAME=model.cfg EXPORT_FOR_SOYA=1
|
|
You can pass as many parameters as you want at the end, "EXPORT_FOR_SOYA=1" is just an
|
|
exemple. The parameters are the same than below.
|
|
|
|
|
|
Logging is sent through python logger instance. you can control verbosity by changing
|
|
log.set_level(DEBUG|WARNING|ERROR|CRITICAL). to print to it use log.debug(),
|
|
log.warning(), log.error() and log.critical(). the logger breaks normal operation
|
|
by printing _all_ info messages. ( log.info() ). Output is sent to stdout and to
|
|
a blender text.
|
|
|
|
Psyco support, turned off by default. can speed up export by 25% on my tests.
|
|
Turned off by default.
|
|
|
|
hotshot_export function to see profile. just replace export with hotshot export
|
|
to see.
|
|
|
|
Any vertices found without influence are placed into a vertex group called
|
|
"_no_inf". [FIXME] i need to stop this for batch more
|
|
running under gui mode the last export dir is saved into the blender registry
|
|
and called back again.
