The orange -> HEAD merge reverted some scripts to older versions. This only affected the ones that already existed before the orange branch. Minor issue, easy to fix. All in all, kudos to kaito, Hos and others for all the hard work in bringing (coding, merging) all these changes to the main branch.

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.
