Previously the only way to get the current image was flaky and relyd on the image being assigned to a mesh.
try:
me = Scene.GetCurrent().getAttiveObject().getData(mesh=1)
image = me.faces[me.activeFace].image
except:
image = None
...Can new be replaced by the following, and works even when there is no mesh.
image = Image.GetCurrent()
epydocs:
Get the currently displayed Image from Blenders UV/Image window.
When multiple images are displayed, the last active UV/Image windows image is used.
Strips with a repeat fraction (like 3.51) should also "hold" on the
fraction of .51 when indicated so.
Patch provided by Roland Hess, but cleaned up (exisiting) mess a bit too.
Unified render didn't treat the alpha for raytraced transparent correct...
unified is based on layering with alpha, so it cannot support alpha in
raytraced transparent correctly.
I'm going to kill unified one day... its giving me headaches. :)
* this resolves a number of outstanding issues with the armature api and gets this ready for release
- add/remove bones possible
- rolls work correctly now!
- ik'ing to parent should work
- flags for tip/root/bone selection
- etc.
30, the databrowse option didnt work.
Made popup menu to go to 60 now, in 3 collums max. Databrowse works too
now.
Next commit; check all other databrowsers for it.
- If a library became unreadable, with a print like:
ERROR: can't find lib //../../../../../../..//jorma_light.blend
Then set the F10 "rt" button to 111. :)
That will read files with a stripping routine to fix it.
- For lost actions in strips: press Lkey in NLA editor, this is the new
"re-link action" option. To get it work, dont forget to fill in the
proper Armature in NKey panel.
The real fix, for the code that corrupted relative paths, will be
part of the bf-blender branch merging, which follows.
particle generator can be duplicated.
Note that the particles are only generated once, on the original, and just
get duplicated.
For static particles it worked already OK.
Added note for previous grouping commit; group-duplicators should support
fully all animation systems, including modifiers and particles.
-> Any Group Duplicate now can get local timing and local NLA override. This
enables to control the entire animation system of the Group.
Two methods for this have been implemented.
1) The quick way: just give the duplicator a "Startframe" offset.
2) Advanced: in the NLA Editor you can add ActionStrips to the duplicator
to override NLA/action of any Grouped Object.
For "Group NLA" to work, an ActionStrip needs to know which Object in a
group it controls. On adding a strip, the code checks if an Action was
already used by an Object in the Group, and assigns it automatic to that
Object.
You can also set this in the Nkey "Properties" panel for the strip.
Change in NLA: the SHIFT+A "Add strip" command now always adds strips to
the active Object. (It used to check where mouse was). This allows to add
NLA strips to Objects that didn't have actions/nla yet.
Important note: In Blender, duplicates are fully procedural and generated
on the fly for each redraw. This means that redraw speed equals to stepping
through frames, when using animated Duplicated Groups.
-> Recoded entire duplicator system
The old method was antique and clumsy, using globals and full temporal
copies of Object. The new system is nicer in control, faster, and since it
doesn't use temporal object copies anymore, it works better with Derived
Mesh and DisplayList and rendering.
By centralizing the code for duplicating, more options can be easier added.
Features to note:
- Duplicates now draw selected/unselected based on its Duplicator setting.
- Same goes for the drawtype (wire, solid, selection outline, etc)
- Duplicated Groups can be normally selected too
Bonus goodie: SHIFT+A (Toolbox) now has entry "Add group" too, with a
listing of all groups, allowing to add Group instances immediate.
-> Library System
- SHIFT+F4 data browse now shows the entire path for linked data
- Outliner draws Library Icons to denote linked data
- Outliner operation added: "Make Local" for library data.
- Outliner now also draws Groups in regular view, allowing to unlink too.
-> Fixes
- depsgraph missed signal update for bone-parented Objects
- on reading file, the entire database was tagged to "recalc" fully,
causing unnecessary slowdown on reading.
Might have missed stuff... :)
This first implementation only supports it for Meshes with UV maps, and
only tangents in V direction.
Tangent diffuse:
http://www.blender.org/bf/0001_0080.avi
Tangent spec, diffuse, and bump:
http://www.blender.org/bf/20001_0080.avi
NOTE: since UV coordinates are still very badly subsurfed, this won't work
well for subsurf meshes... on the todo.
On the todo;
- generate tangents for meshes without UV (with some options)
- use tangents from Curve/Surface
- add the Ashkimin shader from tracker
-----
Important bugfix; curves didn't render anymore since yesterday. :)
(As usual movies disappears after while)
Face example showing stress values on a blend. White is stretch, black
is squeeze
http://www.blender.org/bf/0001_0014.avi
Quick test with softbody stretch
http://www.blender.org/bf/0001_0100.avi
Based on the difference of the "Orco" (original undeformed coordinate)
and the actual render coordinate, a stress value is computed to make
textures react to stretching or wrinking skin.
The texture coordinate is neutral (0) on relaxed state. -1 is squeezed
to zero, +1 is stretched to infinity.
Note that scaling (object itself or parent) also will result in
stress values.
The reason for the huge commit is a cleanup in allocating memory for
the vertices. These were growing too large with new options, so now it
allocates the optional coordinates dynamically.
Saves about 20 MB memory per 1M vertices already. But best of all is that
I now can add much more fun... so tangents, here we come!
In Armature Pose-bone panel, the 'hide' button got replaced with a button
where you can type (TAB complete works) a name for a Mesh Object. It then
draws that Object instead of the indicated bone drawing type.
Fixes for bone layers:
- Akey in Editmode didnt work proper (now deselects all non visible bones
too. selection for editmode works on the vertices, not bones...
- Snap in Editmode now respects layers
Works like for Object layers, but local within Armature itself. Each Bone
can be in (16 now) any layer, and the Armature layer defines what is
visible or not. Also note that hiding will still work too.
Since the Blender code is *stuffed* with Bone options now, this commit
requires a good test if all tools we got now comply to layers...
(I counted 130 cases for checking for selected Bones in code!)
In PoseMode; hotkey M will show 'movetolayer' menu. Not in editmode...
then its the mirror menu.
Todo: make action/nla drawing comply to Armature layer settings.
