* In some cases fluid particles could be born at the exact same locations. Now these cases are just ignored and such particles don't effect each other.
|
|
note: BPY_class_validate() could come in handy later if we need to check classes for properties/functions but for now there is no point in keeping it in.

value to the group sockets. The "expose" function on group inputs/outputs has an optional parameter "add_link", which can be used to prevent the automatic linking.
|

sockets or adding custom sockets by name and type (fixes #26171). Changed a few function names for groups for consistency.

Was trying to free audio data from sequencer strips that don't even have audio. Corrected the error in several ways so this will definitely not happen again :-)

sockets. do_versions is running before the lib_verify_nodetree function updates socket lists of nodes. This means that when adding unlinked sockets in do_versions to restore older node groups, the new sockets are not taken into account. To fix this a temporary node tree flag has been introduced, which delays actual group socket do_version until the group tree internal nodes have been updated. After that the unlinked group sockets are exposed (like old node groups did), then the external sockets look up the new index, so that external links to group instances are preserved.

Node materials with 'ray transparency' set now work again.
Fix provided by Ervin Weber, thanks a lot!

of input/output sockets. Those can be linked to internal nodes just like links between regular nodes. In addition group sockets can be renamed and have a defined order, which can be modified, and they can be removed again.
More details can be found in the patch tracker description (#24883) and on the code.blender.org development blog.

place and so package building scripts can extract it in a more usable way.
this also means we can have a version string like '2.56a-beta' without using buildinfo.
release/VERSION was only used by scons, NSIS installer.
Possibly helps to fix bug [#26062] too.

- Restored BLI_pbvh_grids_update stuff;
- Marc all nodes as changes in ED_sculpt_modifiers_changed, so
draw_buffers would be keept correct.

A very Bad Bug!
On every draw-object, a function free_old_images() was called which
was freeing "unused" images during renders/bakes
This was a left-over from 2.4x code, missed it altogether.
I'm sure this fix will solve a lot of render crashing... :)

also set minimum cmake version to 2.8

rotated.
also skip calculating the dot product if its not needed.

|
* Particle die time wasn't properly taken into account when reading from the cache.
|
|
|
|
* Also removed some unnecessary null checks.

distribution.
|

headers.
left in warnings where functions obviously need to get ported to 2.5x still.
Also, render stamp seq strip works again.

problem and crash
- It turns out we still need the "copyob" still, if for nothing other
than making sure that the unkeyed transforms can get restored. This
was removed originally as I thought that just reevaluating the
animation would work.
- Removed a buggy line of logic that was causing crashes when there
was no animation data. It's better to just assume that if animation
data exists, that something exists there.
- Make Duplicates Real was not clearing data such as the new animation
data or constraints.
|
|
So, it turns out that dupliframes weren't that bad to restore... the
old version didn't do truly accurate transform freezing as it didn't
update ancestors too. However, as a modelling tool, this will probably
suffice.
|
|
* Duplicating particle settings didn't duplicate texture slots.
|
|
intended as a standalone library for use in other applications that
want the same tangent space as Blender.
This also keeps blenkernel clean(er) from extra math functions.
|
|
|
|
|
|
the two files mikktspace.h and mikktspace.c. These are standalone files
which can be redistributed into any other application and regenerate the
same tangent spaces. The implementation is independent of the ordering
of faces and the vertex ordering of faces.
|
|
header static for blenlib, blenkernel and editors.
|
|
- rename rna collection structs Main prefix to BlendData: eg, MainObjects --> BlendDataObjects
- printing python collection now prints its type (when available)
- renamed shadowed vars in bpy_rna.c.
- when making functions static I also made debugging/test functions static, reverse and add definitions to headers instead.
|
|
- fix mistake with grease pencil UI (&& was intended but & used).
- use (void) rather then () across _all_ blenders code.
- a few minor edits, don't shadow stack variables in roll calculation & avoid running memset() for VBO vertex map.
|
|
* New option to distribute particles in a hexagonal grid.
* This is much more stable for fluids than normal grid distribution and looks quite nice otherwise too :)
* Also some small scale code cleanup of grid distribution code.
|
|
|
|
* Moving a texture slot didn't keep the moved slot active.
* Copy & paste for particle textures didn't work.
* New textures weren't freed properly.
|
|
* Particle textures weren't handled properly on texture slot move operations.
|
|
python functions.
- use NULL rather then 0 where possible (makes code & function calls more readable IMHO).
- set static variables and functions (exposed some unused vars/funcs).
- use func(void) rather then func() for definitions.

The changes here were breaking old rigs, for example the right eyeball
in the Sintel rig (which uses the Mirror Modifier and its vertex-group
mirroring functionality)
|
|
mostly replace strcpy with BLI_strncpy and multiple strcat's with a BLI_snprintf().
also fix possible crash if CWD isnt available.

* Renamed the old split uv's animate option "time" to "age" and added a new option to change the used split frame by frame. These are good changes were suggested/implied by Hannu Hoffren over 3 years ago in his tutorial video! (oh my how time flies)
* Also cleaned up the billboard ui quite a bit. For example now the uv channels can be properly chosen from the existing channels.
|
|
* Particle duplis are now always created with render percentage if G.rendering is set.
* This is not yet a perfect solution (hair for example won't yet work correctly), but
it's good to have even partial functionality here until a proper way to handle this
is implemented.

* Greetings from farsthary: particle rotation is now taken into account for particle effector direction.
** This gives all kinds of new possibilities as he shows in his blog http://farsthary.wordpress.com/2011/02/08/vortex-particle-simple-tut/.
**The only modification I made to his patch was to use the actual rotated particle direction as the effector direction as this defaults to the particle velocity vector, so no actual new options are needed.
* I also added an "effector amount" setting for particle effectors so that only a part of the particles can be considered as effectors. This makes it possible to create simple "farsthary vortexes" with only one particle system.
* Also some tiny reorganization of the falloff min/max values for a nicer ui.

==========================
Removed limitation of armatured-only objects for sculpting -- now all
deformation modifiers are allowed in sculpt mode. Use crazyspace corrections
like from transformation modules was used to support all deformation modifiers.
Internal change: all crazyspace-related functions were noved to crazyspace.c
P.S. Brush could make quite unexpected deformation for meshes which are
deformed in specified way. Got patch for this and discussing with Brecht
if it's really needed or maybe it could be done in better way.

- modifier code was using sizeof() without knowing the sizeof the array when clearing the modifier type array.
- use BLI_snprintf rather then sprintf where the size of the string is known.
- particle drawing code kept a reference to stack float values (not a problem at the moment but would crash if accessed later).

* Effecting particle properties with textures was possible in 2.49,
but not in 2.5 anymore.
* Now particles have their own textures (available in texture panel
for objects with particle systems), which are totally separate from
the material textures.
* Currently a basic set of particle properties is available for
texture control. Some others could still be added, but the whole
system is not intended as an "change anything with a texture" as
this kind of functionality will be provided with node particles in
the future much better.
* Combined with the previously added "particle texture coordinates"
this new functionality also solves the problem of animating particle
properties through the particle lifetime nicely.
* Currently the textures only use the intensity of the texture in
"multiply" blending mode, so in order for the textures to effect
a particle parameter there has to be a non-zero value defined for
the parameter in the particle settings. Other blend modes can be
added later if they're considered useful enough.

- transform code was using sprintf reading and writing the same string (undefined behavior).
- softbody had unneeded NULL check.
|
|
|
|
extending the string with strcat. use BLI_snprintf instead.
|
|
- reading pointcache was using an incorrect, always NULL variable.
- commented NDof code, was giving warnings and isnt used now.
