|
|
This script exports selected Blender meshes to AC3D's .ac file format.
|
|
|
|
AC3D is a simple commercial 3d modeller also built with OpenGL.
|
|
The .ac file format is an easy to parse text format well supported,
|
|
for example, by the PLib 3d gaming library (AC3D 3.x).
|
|
|
|
Supported:<br>
|
|
UV-textured meshes with hierarchy (grouping) information.
|
|
|
|
Missing:<br>
|
|
The 'url' tag, specific to AC3D. It is easy to add by hand to the exported
|
|
file, if needed.
|
|
|
|
Known issues:<br>
|
|
The ambient and emit data we can retrieve from Blender are single values,
|
|
that this script copies to R, G, B, giving shades of gray.<br>
|
|
Loose edges (lines) receive the first material found in the mesh, if any, or a default white material.<br>
|
|
In AC3D 4 "compatibility mode":<br>
|
|
- shininess of materials is taken from the shader specularity value in Blender, mapped from [0.0, 2.0] to [0, 128];<br>
|
|
- crease angle is exported, but in Blender it is limited to [1, 80], since there are other more powerful ways to control surface smoothing. In AC3D 4.0 crease's range is [0.0, 180.0];
|
|
|
|
Config Options:<br>
|
|
toggle:<br>
|
|
- AC3D 4 mode: unset it to export without the 'crease' tag that was
|
|
introduced with AC3D 4.0 and with the old material handling;<br>
|
|
- global coords: transform all vertices of all meshes to global coordinates;<br>
|
|
- skip data: set it if you don't want mesh names (ME:, not OB: field)
|
|
to be exported as strings for AC's "data" tags (19 chars max);<br>
|
|
- rgb mirror color can be exported as ambient and/or emissive if needed,
|
|
since Blender handles these differently;<br>
|
|
- default mat: a default (white) material is added if some mesh was
|
|
left without mats -- it's better to always add your own materials;<br>
|
|
- no split: don't split meshes (see above);<br>
|
|
- set texture dir: override the actual textures path with a given default
|
|
path (or simply export the texture names, without dir info, if the path is
|
|
empty);<br>
|
|
- per face 1 or 2 sided: override the "Double Sided" button that defines this behavior per whole mesh in favor of the UV Face Select mode "twosided" per face atribute;<br>
|
|
- only selected: only consider selected objects when looking for meshes
|
|
to export (read notes below about tokens, too);<br>
|
|
strings:<br>
|
|
- export dir: default dir to export to;<br>
|
|
- texture dir: override textures path with this path if 'set texture dir'
|
|
toggle is "on".
|
|
|
|
Notes:<br>
|
|
This version updates:<br>
|
|
- modified meshes are correctly exported, no need to apply the modifiers in Blender;<br>
|
|
- correctly export each used material, be it assigned to the object or to its mesh data;<br>
|
|
- exporting lines (edges) is again supported; color comes from first material found in the mesh, if any, or a default white one.<br>
|
|
- there's a new option to choose between exporting meshes with transformed (global) coordinates or local ones;<br>
|
|
Multiple textures per mesh are supported (mesh gets split);<br>
|
|
Parents are exported as a group containing both the parent and its children;<br>
|
|
Start mesh object names (OB: field) with "!" or "#" if you don't want them to be exported;<br>
|
|
Start mesh object names (OB: field) with "=" or "$" to prevent them from being split (meshes with multiple textures or both textured and non textured faces are split unless this trick is used or the "no split" option is set.

# AC3DExport version 2.44

# Program versions: Blender 2.42+ and AC3Db files (means version 0xb)
|
|
# new: updated for new Blender version and Mesh module; supports lines (edges) again;
|
|
# option to export vertices transformed to global coordinates or not; now the modified
|
|
# (by existing mesh modifiers) mesh is exported; materials are properly exported, no
|
|
# matter if each of them is linked to the mesh or to the object. New (2.43.1): loose
|
|
# edges use color of first material found in the mesh, if any.
