When non-random, particle distribution used a small start offset (to avoid
zero-weight faces), which is fine with "continuous" entities like faces, but not
for discrete ones like vertices - in that case it was generating some undesired
"jump" over a few verts in case step was small enough
(i.e. total number of verts/particles was big enough).
Point-cached particles (those using simulations) would not update at all outside of
first frame, due to PSYS_RECALC_RESET flag being ingnored in `system_step()`...
For some mysterious reasons, udate is still non-fully functional outside of startframe
(e.g. changing face distribution between random and jittered), but at least when choosing
'Vertices' you get particles from verts and not faces!
This feature is also known by the name Samples Offset, which allows
artists to render animation with given amount of samples N, but then
render more samples, starting from N and ending with M (where M > N)
and merge renders together as if they rendered exactly M samples.
Surely such effect could be achieved by changing Seed variable, but
that has possible issues with correlation artifacts and requiring to
manually deal with per render layer samples and such.
While we can't support all possible renderfarm-related features in
Cycles it's nice to support really commonly used stuff.
Here's a command how to run Blender with the new feature enabled:
blender -- --cycles-resumable-num-chunks 24 --cycles-resumable-current-chunk 2
This command will divide samples range in 24 parts and render
range #2 (chunk number is 1-based).
This feature might be changed a bit after we'll do some tests here
in the studio with it.
This reverts commit 2bd3acf7cd27c0c3ee77b10d56b91c3b03226d39.
Commit is valid in theory - but in practice, it means nearly all edited hair systems
would need to be re-created from scratch... Not nice, so better revert and note in code
that particle distribution is ugly and does not respect 'use modifier stack' option in most cases.
As noted by Antonio and Daniel, performing smoothing on the pressure values
for new strokes doesn't work that great. From an artist POV, it is apparently
"very strange that line thickness shrink suddenly after drawing it".
* This includes the "manually create" modes, which correspond to the previous behaviour
for setting up drivers. This is necessary when the current screen layout is not
well suited to having multiple property editors open (e.g. small screen or heavily
subdivided screen).
* Only the modes relevant for the current property type (i.e. array vs single)
will be shown
* The "Add Driver" entries in the RMB context menu have now been replaced by a
submenu which will list all the available mapping types.
* NOTE: The code for the ANIM_OT_button_driver_add() operator is perhaps a bit hairy.
However, it currently allows us to have the desired behaviour. It can always get
cleaned up later though.
Caused by rBc24be7ec6e5.
Before rBc24be7ec6e5, wm_handlers_do always called handlers a second time with event value KM_PRESS in case of a double click. After it, this was only the case for non-LEFTMOUSE events.
Since ui_popup_handler (almost) always returned WM_UI_HANDLER_BREAK, the second handler iteration with KM_PRESS wouldn't run. This fix just makes sure we return WM_UI_HANDLER_CONTINUE for double click events instead (causing second iteration to run).
This never really worked that well, and often ended up being far too strong
to be of practical use. The new options do similar things, but with greater
control, so removing this old method now.
On second thought, these might be better names for these... I'm still not 100%
happy with these, but they will do for now.
(Best results currently seem to be with smooth 0.7, and subdivision steps 1 or 2)
Assuming that this subdivision + smoothing mostly only happens at the end of a stroke
anyway, enforcing this max-points limit in some cases was resulting in strokes that
weren't quite getting subdivided properly as the others.
Improve the quality of current grease pencil strokes adding a new dynamic smooth and subdivision. The level of smooth and subdivide can be adjusted using UI parameters. These options are disabled by default in order to keep the grease pencil stroke compatible with any existing add-on.
Both parameters are defined at layer level.

Unexpectedly found out what was going wrong here. If a file was saved with a filebrowser open, we searched for the channel region in the wrong list (see 'ListBase *regionbase = (sl == sa->spacedata.first) ? &sa->regionbase : &sl->regionbase;').
Minor annoyance is that I had to move the loookup to the 2.77.1 version patch now.
