This script creates "raw" copies of deformed meshes.
|
|
|
|
Usage:
|
|
|
|
Select the mesh(es) and run this script. A fixed copy of each selected mesh
|
|
will be created, with the word "_deformed" appended to its name. If an object with
|
|
the same name already exists, it appends a number at the end as Blender itself does.
|
|
|
|
Meshes in Blender can be deformed by armatures, lattices, curve objects and subdivision, but this will only change its appearance on screen and rendered
|
|
images -- the actual mesh data is still simpler, with vertices in an original
|
|
"rest" position and less vertices than the subdivided version.
|
|
|
|
Use this script if you want a "real" version of the deformed mesh, so you can
|
|
directly manipulate or export its data.
