option after reentering a paint mode.
Solution by Bastien with modifications, thanks!
Show Brush flag need not be reenabled always, but make sure it is at
least enabled once on paint initialization.
* Moved collection key parsing and array index parsing into their own
functions, to make the main path loop easier to follow.
* Unified boolean return values.
In many BI shader setups, the material which owns the nodetree is often itself
included as a node in that nodetree (i.e. to provide the base colour for that
mesh). This would often result in the material (and its subtree) getting included
in the dopesheet results twice.
This can freeze Blender if you accidentally press ctrl+m on a large
script, conversion from text to 3d objects is fairly special case,
restricting access to the menu only.
When the keyframes at either end of the source curve don't lie on exact frame boundaries,
this casued problems with the Cycles F-Modifier, as part of the cycle would get chopped
off.
This was caused by float -> integer truncation that was occurring, since one variable
was of the wrong type. The problem here wasn't discovered until now (thanks to gcc's
invalid-type warnings on printf's) as in standard usage, we can safely assume that all
keyframes are strictly on frame boundaries.
In order to combat the problem of users frequently trying to use inlined
bpy.data/bpy.context paths for data access in their driver expressions
and then finding/complaining that these don't update correctly, the UI
now flags these as the error conditions that they are (with suggestions
on how to fix this).
Also tweaked the "Add Variable" button to have more descriptive text about
what exactly variables are and why to use these, along with some other
visual tweaks (icons!).
All textures are sampled bi-linear currently with the exception of OSL there texture sampling is fixed and set to smart bi-cubic.
This patch adds user control to this setting.
Added:
- bits to DNA / RNA in the form of an enum for supporting multiple interpolations types
- changes to the image texture node drawing code ( add enum)
- to ImageManager (this needs to know to allocate second texture when interpolation type is different)
- to node compiler (pass on interpolation type)
- to device tex_alloc this also needs to get the concept of multiple interpolation types
- implementation for doing non interpolated lookup for cuda and cpu
- implementation where we pass this along to osl ( this makes OSL also do linear untill I add smartcubic to the interface / DNA/ RNA)

dyntopo
Layer brush would not invalidate the layer_disp arrays in dyntopo mode,
checking only for the existence of the array. This means that if a tool
resized the node due to topology changes, the layer brush code could
index (and write!) out of bounds in the array. Solution is to invalidate
the layer data prior to each stroke in dyntopo.
- Added update callback to perform on-update validation when changing the
extrapolation mode on F-Curves
- There was a patch in the tracker for adding an "update()" method to F-Curves
which does a similar thing when manually called by scripts. Since we've added
a function for this in RNA anyways, we might as well add this too while we're
at it. (NOTE: upon closer inspection, the original patch by Tom Edwards had a
number of issues, so I ended up reimplementing here)
in threaded depgraph updates and effector list construction.
Gathering effectors during depgraph updates will call the
psys_check_enabled function. This in turn contained a DNA alloc call
for the psys->frand RNG arrays, which is really bad because data must be
immutable during these effector constructions.
To avoid such allocs the frand array is now global for all particle
systems. To avoid correlation of pseudo-random numbers the psys->seed
value is complemented with random offset and multiplier for the actual
float array. This is not ideal, but work sufficiently well (given that
random numbers were already really limited and show repetition quite
easily for particle counts > PSYS_FRAND_COUNT).
There were 3 bugs with both data types
- using freed memory while sorting.
- sorting failed in some situations.
- scaling allowed multiple items to be on the same frame.
Replace this with a simple sort + de-duplicate, taking selection into account.
Now Alt+RMB,RMB will select all connected boundaries.
There are times when you just want to select an entire boundary loop
ignoring face topology, previously there was no way to do this.
Dyntopo detail in object space. This allows to set the detail in
percentage of blender units and sculpt in this detail constantly,
regardless of the distance to the mesh.
This commit just enables the functionality, which is really trivial.
There will be some more commits like detail flood fill and
detail sampling in the future.
The problem here is that the redraw rectangle can be calculated many
times before actual redraw (for instance due to repetitive calls to the
paint step function for space strokes). Those redraw rectangles need to
be accumulated and finally flushed when the draw call is done.
Also, it is this accumulated rectangle that must account for the
previously drawn rectangle to avoid artifacts due to drawing.
Now all looks like it works correctly :)
after the stroke so that it can be unioned with current rect correctly
during the draw update. For some reason dyntopo clipping misbehaved
before that.
For very thin faces, knife sometimes missed cutting a few.
Problem was that a test for edges being totally inside a face
was being applied in inappropriate circumstances. An assumed
invariant about the knife hit structure is not true when
actually in the middle of making cuts.
Also make a 'big epsilon' a little smaller, though don't think
that was the problem in this bug.
* Do union with previous partial redraw before overwriting with self and
store unmodified new rect to avoid rect getting bigger.
* Make rect one pixel wider instead of smaller so edges do not get left
outside. Overall this looks quite better.
