While it's not there yet, the eventual goal is to support multiple models in the one blend file, so per-object settings is a requirement.

/* This script represents the animation data within the model file. It
|
|
is generated automatically on import, and is optional when exporting.
|
|
If no script is used when exporting, frames will be exported one per
|
|
blender frame from the scene start frame to the scene end frame
|
|
(inclusive), and one skin per teximage node will be exported.
|
|
|
|
The fundamental format of the script is documented at
|
|
http://quakeforge.net/doxygen/property-list.html
|
|
|
|
The expected layout is a top-level dictionary with two expected
|
|
entries:
|
|
frames array of frame entries. If missing, frames will be handled
|
|
as if there were no script.
|
|
skins array of skin entries. If missing, skins will be handled
|
|
as if there were no script.
|
|
|
|
A frame entry is a dictionary with the following fields:
|
|
name The name of the frame to be written to the mdl file. In a
|
|
frame group, this will form the base for sub-frame names
|
|
(name + relative frame number: eg, frame1) if the
|
|
sub-frame does not have a name field. (string)
|
|
frameno The blender frame to use for the captured animation. In a
|
|
frame group, this will be used as the base frame for any
|
|
sub-frames that do not specify a frame. While fractional
|
|
frames are supported, YMMV. (string:float)
|
|
frames Array of frame entries. If present, the current frame
|
|
entry is a frame group, and the frame entries specify
|
|
sub-frames. (array of dictionary)
|
|
NOTE: only top-level frames may be frame groups
|
|
intervals Array of frame end times for frame groups. No meaning
|
|
in blender, but the quake engine uses them for client-side
|
|
animations. Times must be ascending, but any step > 0 is
|
|
valid. Ignored for single frames. If not present in a
|
|
frame group, the sub-frames of the group will be written
|
|
as single frames (in order to undo the auto-group feature
|
|
of the importer). Excess times will be ignored, missing
|
|
times will be generated at 0.1
|
|
second intervals.
|
|
(array of string:float).
|
|
|
|
A skin entry is a dictionary with the following fields:
|
|
name The name of the blender image to be used as the skin.
|
|
Ignored for skin groups (animated skins). (string)
|
|
skins Array of skin entries. If present, the current skin
|
|
entry is a skin group (animated skin), and the skin
|
|
entries specify sub-skin. (array of dictionary)
|
|
NOTE: only top-level skins may be skins groups
|
|
intervals Array of skin end times for skin groups. No meaning
|
|
in blender, but the quake engine uses them for client-side
|
|
animations. Times must be ascending, but any step > 0 is
|
|
valid. Ignored for single skins. If not present in a
|
|
skin group, it will be generated using 0.1 second
|
|
intervals. Excess times will be ignored, missing times
|
|
will be generated at 0.1 second intervals.
