3ds Importer
|
|
|
|
This script imports a 3ds file and the materials into Blender for editing.
|
|
|
|
Loader is based on 3ds loader from www.gametutorials.com (Thanks DigiBen).

0.996 by Mario Lapin (mario.lapin@gmail.com) 13/04/200 <br>
|
|
- Implemented workaround to correct association between name, geometry and materials of
|
|
imported meshes.
|
|
|
|
Without this patch, version 0.995 of this importer would associate to each mesh object the
|
|
geometry and the materials of the previously parsed mesh object. By so, the name of the
|
|
first mesh object would be thrown away, and the name of the last mesh object would be
|
|
automatically merged with a '.001' at the end. No object would desappear, however object's
|
|
names and materials would be completely jumbled.
|
|
|
|
0.995 by Campbell Barton<br>
|
|
- workaround for buggy mesh vert delete
|
|
- minor tweaks
|
|
|
|
0.99 by Bob Holcomb<br>
|
|
- added support for floating point color values that previously broke on import.
|
|
|
|
0.98 by Campbell Barton<br>
|
|
- import faces and verts to lists instead of a mesh, convert to a mesh later
|
|
- use new index mapping feature of mesh to re-map faces that were not added.
|
|
|
|
0.97 by Campbell Barton<br>
|
|
- Strip material names of spaces
|
|
- Added import as instance to import the 3ds into its own
|
|
scene and add a group instance to the current scene
|
|
- New option to scale down imported objects so they are within a limited bounding area.
|
|
|
|
0.96 by Campbell Barton<br>
|
|
- Added workaround for bug in setting UV's for Zero vert index UV faces.
|
|
- Removed unique name function, let blender make the names unique.
|
|
|
|
0.95 by Campbell Barton<br>
|
|
- Removed workarounds for Blender 2.41
|
|
- Mesh objects split by material- many 3ds objects used more then 16 per mesh.
|
|
- Removed a lot of unneeded variable creation.
|
|
|
|
0.94 by Campbell Barton<br>
|
|
- Face import tested to be about overall 16x speedup over 0.93.
|
|
- Material importing speedup.
|
|
- Tested with more models.
|
|
- Support some corrupt models.
|
|
|
|
0.93 by Campbell Barton<br>
|
|
- Tested with 400 3ds files from turbosquid and samples.
|
|
- Tactfully ignore faces that used the same verts twice.
|
|
- Rollback to 0.83 sloppy un-reorganized code, this broke UV coord loading.
|
|
- Converted from NMesh to Mesh.
|
|
- Faster and cleaner new names.
|
|
- Use external comprehensive image loader.
|
|
- Re intergrated 0.92 and 0.9 changes
|
|
- Fixes for 2.41 compat.
|
|
- Non textured faces do not use a texture flag.
|
|
|
|
0.92<br>
|
|
- Added support for diffuse, alpha, spec, bump maps in a single material
|
|
|
|
0.9<br>
|
|
- Reorganized code into object/material block functions<br>
|
|
- Use of Matrix() to copy matrix data<br>
|
|
- added support for material transparency<br>
|
|
|
|
0.83 2005-08-07: Campell Barton
|
|
- Aggressive image finding and case insensitivy for posisx systems.
|
|
|
|
0.82a 2005-07-22
|
|
- image texture loading (both for face uv and renderer)
|
|
|
|
0.82 - image texture loading (for face uv)
|
|
|
|
0.81a (fork- not 0.9) Campbell Barton 2005-06-08
|
|
- Simplified import code
|
|
- Never overwrite data
|
|
- Faster list handling
|
|
- Leaves import selected
|
|
|
|
0.81 Damien McGinnes 2005-01-09
|
|
- handle missing images better
|
|
|
|
0.8 Damien McGinnes 2005-01-08
|
|
- copies sticky UV coords to face ones
|
|
- handles images better
|
|
- Recommend that you run 'RemoveDoubles' on each imported mesh after using this script
