- moved bpydata/ to scripts/bpydata/ and added a config/ subdir to it; - created scripts/bpymodules for py modules (also got rid of those "mod_"'s appended to the files); - updated scripts accordingly. This will require you to "reinstall" (just copy the scripts/ dir over your older one) if you have a .blender/scripts/ dir somewhere. Otherwise some scripts won't work. You can use the updated "Help->System->System Information" script here to check all is fine. An installer script yet to be written will help users with these issues, specially to make the user defined dir have the same structure expected from the default scripts dir, so the basic facilities (module search; saved config data; scripts: installer, help browser, config editor) are also available for a user's own collection of written and downloaded scripts. BPython: - slikdigit's crash was because he had no <home or blender exe location>/.blender/: proper check added and also now if all else fails the <cvsblender>/release/scripts/ dir is also searched for scripts. All this registration dirs stuff is a little messy (installation!), so please report any troubles (I only tested on linux). - slight change in error report in BPY_interface.c's BPY_menu_do_python; remembering to set globaldict pointer to NULL there, too. - moved bpy_gethome() to EXPP_interface.[ch] - "//" as user defined python dir is ignored while looking for scripts, considering it's only a default some users use, not really meant for a scripts dir.

This script imports Nendo files to Blender.
|
|
|
|
Nendo is (was) a commercial polygon modeler that has about half of the
|
|
features found in Wings. The .ndo file format is a simple, uncompressed,
|
|
memory dump of structures that represent the mesh objects, uv coords,
|
|
and image textures.
|
|
|
|
Usage:<br>
|
|
Execute this script from the "File->Import" menu and choose a Nendo file
|
|
to open.
|
|
|
|
Supported:<br>
|
|
Meshes only.
|
|
|
|
Missing:<br>
|
|
Materials, UV Coordinates, and Vertex Color info will be ignored.
|
|
|
|
Known issues:<br>
|
|
Triangulation of convex polygons works fine, and uses a very simple
|
|
fanning algorithm. Convex polygons (i.e., shaped like the letter "U")
|
|
require a different algorithm, and will be triagulated incorrectly.
|
|
|
|
Notes:<br>
|
|
Last tested with Wings 3D 0.98.25 & Nendo 1.1.6. Some models cannot be
|
|
imported due to the fact that Nendo erroneously creates doubled back
|
|
edges during the course of modeling.
