Updated Python Mesh API to support UV and Color layers with names.
Similar to vertex group's
renamed a function in customdata.c CustomData_free_layers -> CustomData_free_layers_active and made CustomData_free_layers accept an index, this is needed so python could free layers that arnt active.
Now the Snap To Location (Shift S) tools for bones in pose-mode
work correctly. Previously, only one of these tools was implemented,
but it only worked in some cases.
This fixes item #4874 in Todo Tracker. Was patch #5012.
Now uses original filename for unpacking, instead of the Blender ID name.
That latter was a nice idea, but because of its 20 char maxname limit
not working well.
Added support for multiple UVs in the render engine. This also involved
changing the way faces are stored, to allow data to be added optionally
per 256 faces, same as the existing system for vertices.
A UV layer can be specified in the Map Input panel and the Geometry node
by name. Leaving this field blank will default to the active UV layer.
Also added sharing of face selection and hiding between UV layers, and at
the same time improved syncing with editmode selection and hiding.
Still to do:
- Multi UV support for fastshade.
- Multires and NMesh preservation of multiple UV sets.
(saved files cannot read back, they crash).
The implementation of this option was plain accident that it even worked
once... you cannot use the API in blender that way.
This header defines function stubs for builds without OpenEXR.
A quote from openexr_multi.h:
/* ugly... but we only use it on pipeline.c, render module, now */
No longer true! Function definitions should never be in header files,
I say.
Please read:
http://www.blender3d.org/cms/Imaging.834.0.html
Or in short:
- adding MultiLayer Image support
- recoded entire Image API
- better integration of movie/sequence Images
Was a whole load of work... went down for a week to do this. So, will need
a lot of testing! Will be in irc all evening.
* Patch #5442: "Fix Bone SizeLimit" by Heriberto Mendez (gammarayq21)
'Limit Scale' constraint can now work on bone's local scaling too.
* I've also made the 'Copy Scale' constraint able to use the local scaling
of bones too.
Updated id properties interface as per
discussed in python meeting. Basically,
id properties are now entirely accessed
through the dict-like interface if IDGroupType.
Also, tp_getsetters are used throughout the code
now.
Using the dict interface allowed for a major cleanup
of the wrapping code. The biggest change is that ID
properties are no longer wrapped in a structure with
.type .name and .data members; instead when you get
properties from the group it returns the direct value.
Ints, strings and floats return simple python types,
while arrays and groups return special wrappers though.
This means to detect the type of an ID property, you
have to use type(). For string and int types this is
easy; for group and array types (which of course have
their own wrappers) you use type() with Blender.IDGroupType
or Blender.IDArrayType.
Update of epydocs plus a temporary gui script will be
forthcoming; the gui script will be removed before release
as of course by then we'll have a built-in gui for id
properties.
had new dependencies added internally (like constraints), changing the
evaluation order for pose channels. My optimized code didn't like it, so
now it falls back to a reliable slower method.
Bug showed as totally messed up characters for proxies...
Also: increased range for 3D Window properties clip-start/end, this is
still a bad construct though...
added python api stuff to deal with Color and UV/Image layers.
me.activeUvLayer - int
me.activeColorLayer - int
me.totUvLayers - int
me.totColorLayers - int
me.addUvLayer()
me.addColorLayer()
me.removeUvLayer()
me.removeColorLayer()
Variable names may need changing.
These can be created and deleted in the Mesh panel in the same place as
before. There is always one active UV and vertex color layer, that is
edited and displayed.
Important things to do:
- Render engine, material support
- Multires and NMesh now lose non active layers
Also CustomData changes to support muliple layers of the same type, and
changes to layer allocation, updated documentation is here:
http://mediawiki.blender.org/index.php/BlenderDev/BlenderArchitecture/CustomData
#5417: Only Shadow material gave shadow outside of Spot bundle
#5414: Material Nodes: sockets without input were always treated as single
value inputs, ignoring color or vector. (Caused by commit to do
automatic conversions of socket links).
#5420: When reading with old Blender a new file that has a new window type,
saving it over, and read back in current Blender, the window type
should be reset to EMPTY, because all its data got lost.
Material Nodes still have undefined output to the passes. Currently only
the active Material node gives pass info. Bug was that check for active
was wrong, giving stripes because of hanging variables.
I'll work soon on providing all pass options in the Material nodes. This
fix at least correctly provides passes for active material, and clears
memory of pass info in advance.
Also: outliner view "current scene" did not show render layers.
ALso: outliner click on renderlayer now activates it (for UI)
Also: zbuffer for transparent was not initialized to 'infinity' correctly
- New Passes: UV and Rad(iosity)
- New Nodes: UV Map and Index Mask
- Z-combine now is antialiased
As usual, please check the log. Has nice pics!
http://www.blender3d.org/cms/Composite__UV_Map__ID.830.0.html
For devs: the antialias code from Vector Blur is now exported in compo
too. Works pretty good. Even fixed a bug in antialias, so vectorblur
will be better.
Also: found out that OpenGL display list speedup accidentally was still
triggered with the rt button... so it did not work by default.
----------
Bugfix #5373: creating a curve or text object using Object.New() without
linking any data to the object would later cause a segfault when ob->data
was later dereferenced. This problem will be fixed (hopefully soon) in the
API when new objects are created with data and linked to scenes all in one
step, but for now check for curves that ob->data is defined before using,
otherwise print an error message to the console and skip the object.
- Removed stupid idea to insert convertor nodes in Node Shaders, when a
link is created by non-matching sockets. Now it works like Compositor,
doing a default conversion. Works like this:
1 from 3 or 4 values: take average
3 from 1: copy to all
3 from 4: copy 3
4 from 1: copy to 3, set alpha to 1
4 from 3: copy 3, set alpha to 1
- Added select-linked in Nodes. Lkey or Shift+L. Also in pulldown menus
- Bug: material emit was ignored (showed in preview render backdrop)
- Bug: world exposure was ignored
- Bug: lamp halo was ignoring 'render layer light override'.
Further reshuffled the way shadows are being pre-calculated, this to enable
more advanced (and faster) usage of Material lightgroups. Now shadows are
being cached in lamps, using a per-sample counter to check if a recalc is
needed. Will also work (later) for Raytracing node shaders.
- New: Material LightGroup option "Always", which always shades the lights
in the group, independent of visibility layer. (so it allows to move such
lights to hidden layer, not influencing anything).
edges in Editmode
This bug was due to CCGDerivedMesh (the DerivedMesh backend used to store
editmode subsurf results) not copying edge flags correctly, meaning that
they were unavailable to the EdgeSplit modifier. I have updated
CCGDerivedMesh to copy edge flags correctly.
Full log:
http://www.blender3d.org/cms/Render_Passes.829.0.html
In short:
- Passes now have option to be excluded from "Combined".
- RenderLayers allow to override Light (Lamp groups) or Material.
- RenderLayers and Passes are in Outliner now, (ab)using Matt's nice
'restriction collumns'. :)
IDP_GroupIterNext returned void* rather then IDProperty*.
Made it IDProperty*.
BTW, any people out there interested in using IDProperties
from the C side, feel free to email me comments and (especially!)
file bugreports assigned to me in the tracker. :)
- Unitialized variable in new shadow code caused Sun lamp shadow to not
work.
- Ipo handle bug: when the handle was vertical it flipped around
- Loop select: unitialized variable caused it to work unpredictable in
cases. Also found an unitialized var in collaps_edgeuvs().
- Crash, caused by commit of 1 hour ago to fix 'All Z' render problem
- Bug: yesterday's fix for node material renders caused some issues with
precalculating correct shadow.
- Composite Translate node: input sockets allowed multiple inputs
- Blur nodes didn't accept RGB buffers (only RGBA or single channel ones)
- Mix node had maximum for 'mix' on 1.0, for passes edit that could become
more, made it 5!
This commit upgrades the modifier stack to only calculate the data which is
needed, either by modifiers further down the stack or by other functions at
the end of the stack (e.g. drawing functions).
This speeds up modifier stack recalculation, especially where vertex
groups and UV coordinates are concerned. For example, a mesh with an Armature
modifier followed by a Subsurf modifier would previously have required the
Subsurf modifier to interpolate all the vertex groups in the mesh, slowing
down modifier calculations considerably. With this update, vertex group data
is not propagated beyond the Armature modifier, so calculations are faster.
Note that this depends on the order of modifiers in the stack. If the Armature
and Subsurf modifiers were swapped in the above example, the Subsurf modifier
would have to interpolate vertex groups, as they are needed by the Armature
modifier.
