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.

|

This script is used to mirror vertex locations and weights
|
||||
It is usefull if you have a model that was made symetrical
|
||||
but has verts that have moved from their mirrored locations slightly,
|
||||
casuing blenders X-Mirror options not to work.
|
||||
|
||||
Weights can be mirrored too, this is usefull if you want to model 1 side of a mesh, copy the mesh and flip it.
|
||||
You can then use this script to mirror to the copy, even creating new flipped vertex groups, renaming group name left to right or .L to .R
|
||||
|
||||
Vertex positions are mirrored by doing a locational lookup,
|
||||
finding matching verts on both sides of a mesh and moving to the left/right or mid location.
|
||||
|
||||
The vertex weights work differently, they are mirrored my location also,
|
||||
but they mirror in pairs, rather it works by finding the closest vertex on the flip side and using its weight.
|
||||
|
||||
When a location mirror is finished, verts that have not been mirrored will remain selected.
|
||||
a good way to check both sides are mirrord is to select the mirrored parts,
|
||||
run this script with default options and then see of there are any selected verts.
|
||||
|
||||
For details on each option read the tooltips.
