* Added a new "color spread" slider for "spread" effect to adjust how much colors get mixed.
* Improved smudge behavior on "wet" paint.
* Displace can now be set "incremental". This way it's added on top of previous displace.
* Added "displace clamp" setting. You can use it to limit maximum amount of displace.
* Fix: velocity data wasn't always initialized, this could lead to no effect at all or crash.
* Fix: Vertex color rendering near zero alpha values was still incorrect.
* Object velocity can now be used to determine brush influence and color.
* Brushes can now be set to "smudge" existing paint.
* Added new operators to easily add and remove surface output mesh data layers from Dynamic Paint ui.
* Fixed drip effect algorithm to work properly on forces pointing towards surface.
* Adjusted drip effect speed.
* Drip effect can now use canvas velocity and acceleration to influence drip direction.
* Fixed texture mapping for material enabled brushes.
* "Object Center" type brushes can now use "material color" as well.
* Improved surface partitioning grid generation algorithm.
* Fixed possible invalid brush collision detection when OpenMP enabled.
* Fixed incorrect random sized particle displace/wave influence.
* Fixed "Object Center" brush color ramp falloff.
* Fixed invalid zero alpha sampling when rendering vertex colors.
* Lots of smaller tweaking.
* Added alpha support renderer for vertex colors. You can now easily render Dynamic Paint produced vertex colors by checking "Vertex Color" in material options.
* Added "Vertex Alpha" socket for "Geometry" material node.
* Fixed vertex surface color output issues.
This commit fixes very noticeable seams caused by margins
calculated incorrectly. This commit changes way margin is
calculated in and makes textures really seamless.
Also margin limited to 32 isn't good now -- artists are baking
really large textures nowadays so margin is now limited to 64px.
Thank you, Morten!
This fixes bug #26764 and several others like it, where modifier
properties (and others, but most visibly modifiers) would not do
anything when animated or driven, as modifier properties require the
RNA update calls to tag the modifiers to get recalculated.
While just adding a call to RNA_property_update() could have gotten
this working (as per the Campbell's patch attached in the report, and
also my own attempt #25881). However, on production rigs, the
performance cost of this is untenatable (on my own tests, without
these updates, I was getting ~5fps on such a rig, but only 0.9fps or
possibly even worse with the updates added).
Hence, this commit adds a property-update caching system to the RNA
level, which aims to reduce to the number of times that the update
functions end up needing to get called.
While this is much faster than without the caching, I also added an
optimisation for pose bones (which are numerous in production rigs) so
that their property updates are skipped, since they are useless to the
animsys (they only tag the depsgraph for updating). This gets things
moving at a more acceptable framerate.
* Surface bake data is no longer recalculated every frame, but only when surface mesh has moved/transformed. Results in multiple times better performance on high resolution surfaces when using sub-steps or surface is still.
* Heavily optimized particle brushes when random particle size enabled. Up to 10x speedup with large radius particles.
* Added an additional "grid" space partitioning structure for surfaces.
* Added bounding box checks for brushes.
* Smaller overall optimization.
* Further OpenMP parallelization.
* Added physics tab link to modifier panel.
* Fix: "Point Density" texture cache wasn't properly updated. Brushes can now use Point Density textures as well.
* Fix: Paint dissolve resulted in black color.
* Fix: KD-tree checkups weren't completely thread safe. Fixes possible crash with OpenMP enabled particle brushes.
* Fix: When brush was set to use a specific material, it was saved incorrectly and resulted in potential crashes on next load.
Blender render optimizes alpha=0 materials away, unless it has
a number of properties... but there wasn't a check for material
being ray-mirror, it then should be rendered always.
* Noise is now considered an animated texture as it changes with every frame
* Converted a few places in particles code to use the particle system's own random table instead of BLI_frand.
It was a regression introduced in rev36301. Average normal calcilation
used to fail due to triangular faces which are too slight.
Do not use triangles with too small area for average normal calculation.
