Series of fixes in Library linking of groups;
- On library-linking (SHIFT-F1) a Group, the Objects now don't get a "Base"
anymore, meaning they won't show up as Objects in the Scene.
This ensures you can use the linked Group as duplicator without having
your file polluted with new (and linked) objects.
(I realize it should be possible to have it with Base too, will check)
- On append or file-read, the linked Group Objects get drawn properly,
but the animation system doesn't run yet.
- Group buttons (F7) now shows if a Group is from Library
- Outliner draws Library linked data with blue-ish text
Other fixes;
- Using group-duplicator, with originals in hidden layer, now shows and
updates animated Objects correctly.
- All of Object button panels did not have a proper protection against
editing Library data.
Previous experiment (in 2000) didn't satisfy, it had even some primitive
NLA option in groups... so, cleaned up the old code (removed most) and
integrated it back in a more useful way.
Usage:
- CTRL+G gives menu to add group, add to existing group, or remove from
groups.
- In Object buttons, a new (should become first) Panel was added, showing
not only Object "ID button" and Parent, but also the Groups the Object
Belongs to. These buttons also allow rename, assigning or removing.
- To indicate Objects are grouped, they're drawn in a (not theme yet, so
temporal?) green wire color.
- Use ALT+SHIFT mouse-select to (de)select an entire group
But, the real power of groups is in the following features:
-> Particle Force field and Guide control
In the "Particle Motion" Panel, you can indicate a Group name, this then
limits force fields or guides to members of that Group. (Note that layers
still work on top of that... not sure about that).
-> Light Groups
In the Material "Shaders" Panel, you can indicate a Group name to limit
lighting for the Material to lamps in this group. The Lights in a Group do
need to be 'visible' for the Scene to be rendered (as usual).
-> Group Duplicator
In the Object "Anim" Panel, you can set any Object (use Empty!) to
duplicate an entire Group. It will make copies of all Objects in that Group.
Also works for animated Objects, but it will copy the current positions or
deforms. Control over 'local timing' (so we can do Massive anims!) will be
added later.
(Note; this commit won't render Group duplicators yet, a fix in bf-blender
will enable that, next commit will sync)
-> Library Appending
In the SHIFT-F1 or SHIFT+F4 browsers, you can also find the Groups listed.
By appending or linking the Group itself, and use the Group Duplicator, you
now can animate and position linked Objects. The nice thing is that the
local saved file itself will only store the Group name that was linked, so
on a next file read, the Group Objects will be re-read as stored (changed)
in the Library file.
(Note; current implementation also "gives a base" to linked Group Objects,
to show them as Objects in the current Scene. Need that now for testing
purposes, but probably will be removed later).
-> Outliner
Outliner now shows Groups as optio too, nice to organize your data a bit too!
In General, Groups have a very good potential... for example, it could
become default for MetaBall Objects too (jiri, I can help you later on how
this works). All current 'layer relationships' in Blender should be dropped
in time, I guess...
Once an Object Ipo position was inserted, the object couldn't be moved when
a particle system was tied to it. Needed code to copy object settings,
before the particle animation was done.
Duplicated objects, that have modifiers, didn't render (or not correct).
Bug reported case with softbody being duplicated.
The duplicator system is ancient... integration with new derivedmesh or
modifiers has not been really done yet.
New diffuse shader, "Fresnel", which using existing fresnel formula.
Since it hilights edges (away from lamp), nice to fill darker parts with
the new layering system.
Weird stuff though;

(Movie disappears in a couple of days!)
Note; for ray-shadow you need to use the Bias, to prevent 'terminator'
problems. I made that option default now.
- Texture buttons preview didn't show for material layers
- layers now have a 'number of users' button, which allows to make a
full copy of the material.
Forgot to put back window/screen-size clipping when opening render window.
Note for windows coders; check this diff, here's where you might need to
add an ifdef too for windows, to get the window opening correct for the
top of the screen (probably because of windows bottom toolbar?)
(WIP, don't bugs for this in tracker yet please!)
- New Panel "Layers" in Material buttons, allows to add unlimited amount
of materials on top of each other.
- Every Layer is actually just another Material, which gets rendered/shaded
(including texture), and then added on top of previous layer with an
operation like Mix, Add, Mult, etc.
- Layers render fully independent, so bumpmaps are not passed on to next
layers.
- Per Layer you can set if it influences Diffuse, Specular or Alpha
- If a Material returns alpha (like from texture), the alpha value is
used for adding the layers too.
- New texture "Map To" channel allows to have a texture work on a Layer
- Each layer, including basis Material, can be turned on/off individually
Notes:
- at this moment, the full shading pass happens for each layer, including
shadow, AO and raytraced mirror or transparency...
- I had to remove old hacks from preview render, which corrected reflected
normals for preview texturing.
- still needs loadsa testing!
- There is now a (temporary) dropdown box in the image window header for
switching between the old an new unwrapper code. So to test the changes
described below you need to enable the new unwrapper code.
- Pinning is now more predictable, if one uv is pinned, the others belonging
to the same vertex are pinned also.
- Live LSCM is much faster, since the LU factorization, the most expensive
part of the computation, is now stored and reused (was Jens' idea).
- Packing multiple uv charts is slightly improved, by doing a binary search
over the texture width. This fixes the case where all the charts are
packed at the bottom of the image.
- LSCM now uses an angle based formulation, and the results seem somewhat
different (maybe slightly better?), didn't find out why yet.
thus directories in the path are created using RE_make_existing_file
in fluidsim.c)
- changed default output to be '//fluidsimdata/...'
- hopefully fixed bugs #3466 and #3470 (orco texture coords caused
problems when the fluidsim mesh was bigger than the original one,
one no other deformations were used - new deformedVerts are now
allocated in this case in DerivedMesh.c)
(Swap colors on bigendian machines)
I also made it so that the env variable is tried ahead of all
of the other looking. (That way you can override a system default
if its broken without having to upgrade)
This also makes it so we can remove the OSX ifdef. So I did.
lukep: If you still want it add it back in but my gut says the less ifdefs
we have the better ;)

I updated gen_dynlibtiff.py so its in sync with the file(s) it creates.
I added a little more documentation to the readme.txt for adding
new file formats.
I also added two dummy functions to the tiff.c so it stopped whining
about them being NULL.
(I'm still working on the reported bugs but thought this was a good time
to at least get this in)

Set the option in EditMode, in 2nd mesh tools panel. It only works on
transform options now (grab/rot/scale), and of course assumes a near-
perfect symmetrical mesh. Mesh Object itself can be on any location
though (and rotated etc).
you can now blend between the original and minimized.
Stretch minimizing trades conformality (= perfect squares in checkerboard
texture) for a better sampling of the texture (= often not so well shaped
checkerboard), so it is useful to let the user find a balance between the
two.
This commit adds new underlying uv unwrapper code, intended to be
more extensible. At the moment this has a re-implementation of LSCM.
This has not been activated yet, since it doesn't add anything new.
What's new is the stretch minimize tool from tuhopuu. It works by
selecting some some uv's in the uv editor window, and then pressing
ctrl+V. The uv's on the boundary stay fixed.
More stuff will follow as I port it over & fix it.
