fixed some bugs in BPyMesh_redux, tweaked to work well for test cases. much better use of error levels for edge weighting. better collapsing to the desired target. triangulates before reduction be default now.
* Much improved, slower edge collapse weighting method that makes this script about 2.5x slower, but brings it up to the quality of qslim (lightwave's decimator), without the manifold' errors.
Probably worth adding a UI front end to this function.
You can grag the keyframes around from anywhere in the animation.
Keyframe dragging would be less of a hack if we could do an event handeler and a redraw space handeler in 1.
This kind of functionality could be nice to see in Blender.
vertex it would potentially loop through every face). This fix speeds
it up a bit (only loops through all faces once, at the cost of some
additional memory). An example of export times for a mesh with 6266
verts and 12528 faces:
Before: 2m56s
After: 8s
Isnt intended to be ultra high quality, more for automatic realtime "Level of Detail" model generation.
BPyMesh.redux(ob, 0.5) # To reduce to about half the polys
renamed meshPrettyNormals to meshCalcNormals, and it now writes to normals rather then returning a list of vecs.
updated vertexpaint_selfshadow_ao to be a bit more efficient and make use of the above changes.
* clean weights (removed low weights)
* normalize, maximizes weights to a user set peak, optionaly scales other groups too to keep the proportion of the weights even. (Doubles as a weight scaler)
* Grow/Shrink, uses the mesh topology to expand/contract the vert weights. a few options for iterationsm, max length and strength.
I need a way tell if the users in Face Select mode (in python) so I can make use of the selected face flag.
Will need to do some updates, Mesh over NMesh and optimize some areas but it works and is a big improvement.

Detailed description:
Modified the 3ds export script 3ds_export.py:
- It now exports face UV correctly. 3ds only supports one UV coordinate per vertex. The script now duplicates vertices that had multiple UV pairs assigned to them so that each duplicate now only contains one and only one UV. Faces have their vertex indices adjusted accordingly.
- Quads are now split into triangles better. 3ds only supports triangles, so quads need to be split into two triangles. Instead of rather arbitrarily splitting along the diagonal between points 0 and 2, the script now splits along the shortest diagonal. This creates a higher quality triangular mesh, as well as better preservation of symmetry.
- Now creates an object node block, exporting object nodes, needed by some 3D importers. Among others, allows one to export object hierarchy.
- Now exports Empties as 3ds Dummies.
To be able to add all of the above new features, the script has been mostly rewritten and strongly restructured.
Motivation for the rewrite was the desire to be able to use Blender to produce custom 3d cars for Trackmania:Sunrise (TM:S). Previously, the TM:S importer could not correctly handle the 3ds files from the Blender 3ds export script. With this version, one can export cars complete with UV textures, correct wheel placement and light placement. To my knowledge, this script would make Blender the first fully free 3d modeller that allows one to export 3ds models for TM:S (expect a tutorial soon). The ability to have proper UV coordinates exported into the 3ds file should also be very welcome to many.
Add A Comment: Notepad
We need a way to get worldspace loc/size/rot.
there is currently no simple way to do this. location can be found the the world matrix.
but size and rot arnt that simple...
Maybe worldLocX.. worldRotX etc?
- dictWeightFlipGroups, return a vert weight with flipped group names.
- dictWeightMerge, takes a list of dictWeights and merges them
mesh_mirror_tool.py
Added vertex weight support for the mirror tool, its able to mirror arbitary meshes weights with optional name flipping and creation of name flipped groups.
This also uses the mode for l<>r, l>r, r>l so you can copy from left to right only for eg.
fixed the "No X Crossing option "Made 0-x verts snap to eachother.
Added mesh_mirror_tool
This is a tool that makes verts mirror, so that you can use xmirror in editmode and weight painting.
Have imported a heap of models that are made mirrored but are slightly out of being in the range that blender uses to be mirrored.
So this means I can make a models verts snap to its mirrored locations.
Options are Limit, Mode l>R, R>L or Middle, Normal Weigting, only mirror Same edge user count may add support for mirroring vert weights later.
Running this script is usefull for moving projects to new computers and fixing broken image paths.
It works by taking a searchdir and finding all the images in that dir, then using the largest images (if doubles are found) to avoid using thumbnails.
This should be mived from the UV to the image menu when a python slots available.
Exporter free's mesh vertex data each run (was causing memory errors when exporting fluidsim meshes... poke ken for Mesh.Unlink() since many meshes are still created)
Exporter had an indentation error also.
Added an NMesh wrapper around Mesh for importers to use, so as to work around slow 1 by 1 adding of data. used in upcoming flt_importer update.
Mesh cleanup now has the dangerous option to perform a cleanup on ALL mesh data. (needed it for a project)
Made obj_export use getMeshFromObject
obj_export now copies images from mtex as well as texface when copy images enabled.
obj_export tested to work with exporting fluidsim animations (somebody reported it was broken, must have been fixed at some point?)
