2020-10-21Fix panel type use after free when reloading scriptsHans Goudey
In order to prevent the panel code from using the type after it is freed, the field needs to be set to NULL. This needs to be done recursively for subpanels as well as top-level panels.
2020-10-21Preferences: separate feature flags for geometry nodes and point cloud typeJacques Lucke
Those two features are not directly related and one might be activated in master earlier than the other. WITH_PARTICLE_NODES was removed, because we continue the project under the name "Geometry Nodes".
2020-10-21Fluid: Added obstacle fluid distance parameterSebastián Barschkis
Being able to adjust the distance between fluid and obstacles comes in handy when trying to achieve a fluid motion over inclined obstacles. Depending on the slope of such obstacles, already small adjustments of this value can help when particles stick to obstacle surfaces (i.e. make particles not stick to obstacles).

2020-10-20UV/Image: Remove Legacy DrawingJeroen Bakker
With D8234 a new drawing method for UV/Image editor was introduced. For debugging reasons we left the old drawing method in the code base. This patch will remove the old drawing method. Reviewed By: Clément Foucault Differential Revision: https://developer.blender.org/D9011

2020-10-20Simulation: remove particle nodes with outdated designJacques Lucke
The design for how we approach the "Everything Nodes" project has changed. We will focus on a different part of the project initially. While future me will likely refer back to some of the code I remove here, there is no point in keeping this code around in master currently. It would just confuse other developers working on the project. This does not remove the simulation modifier and data block. Those are just cleaned up, so that the boilerplate code can be reused in the future.
2020-10-20Sculpt: Smooth deform type for Boundary BrushPablo Dobarro
This adds a smooth deformation type to the boundary brush, which smooths the boundary and has a regular falloff towards the inside of the mesh. For smoothing, only vertices parallel to the boundary are taken into account, creating this effect. Reviewed By: sergey Differential Revision: https://developer.blender.org/D9204

2020-10-19Volumes: new Volume to Mesh modifierJacques Lucke
This modifier is the opposite of the recently added Mesh to Volume modifier. It converts the "surface" of a volume into a mesh. The "surface" is defined by a threshold value. All voxels with a density higher than the threshold are considered to be inside the volume, while all others will be outside. By default, the resolution of the generated mesh depends on the voxel size of the volume grid. The resolution can be customized. It should be noted that a lower resolution might not make this modifier faster. This is because we have to downsample the openvdb grid, which isn't a cheap operation. Converting a mesh to a volume and then back to a mesh is possible, but it does require two separate mesh objects for now. Reviewers: brecht Differential Revision: https://developer.blender.org/D9141
2020-10-18Fluid: Fix for issues with external forcesSebastián Barschkis
A general refactor / fix commit that should clear out the issues that have been reported on external forces and moving effectors (e.g. T79537, T81660, T80088).

2020-10-16RNA: support building WITH_PYTHON=OFFCampbell Barton
2020-10-15Fix brush tip delta orientation with anchored strokesPablo Dobarro
When using anchored stroke, the stroke operator was modifying the coordinates on the "mouse" rna property by setting them to the original position. Because of this, all the sculpt delta calculation was failing and the delta for these brushes was set randomly (with a 0 vector) at the beginning of the stroke. There is now an extra property that uses the unmodified coordinates of the mouse to calculate the delta. Now delta orientation works as expected in all brushes and features that require brush tip orientation. Reviewed By: sergey Differential Revision: https://developer.blender.org/D9183
2020-10-15Sculpt: Experimental Pen Tilt SupportPablo Dobarro
This adds support for pen tilt in sculpt mode. For now, pen tilt is used by tweaking the tilt strength property, which controls how much the pen angle affects the sculpt normal. This is available in Draw, Draw Sharp, Flatten, Fill, Scrape and Clay Strips brushes, but it can be enabled in more tools later. The purpose of this patch is to have a usable implementation of pen tilt in a painting mode, so users can test and see in which hardware and platforms this feature is supported and how well it works. If it works ok, more tools and features that rely on pen tilt can be implemented, like brushes that blend between two deformations depending on the angle.

This way particles can be saved with the custom OpenVDB precision options that were introduced in the latest Mantaflow update.
2020-10-13Sculpt: Use plasticity for softbody influencePablo Dobarro
Previously the softbody strength property was controlling the strength of the constraints that pin all vertices to the original location. This was causing problems when the forces were trying to deform the vertices too much, like when using gravity or grab brushes. Now softbody is implemented with plasticity, which creates constraints to a separate coordinates array. These coordinates are deformed with the simulation, and the plasticity parameter controls how much the simulation moves the coordinates (plasticity 0), or the coordinates move the simulation back to its previous position (plasticity 1). This creates much better and predictable results and adding softbody plasticity to the brushes can increase its control and the stability of the simulation.

2020-10-13Property Search: Find results in all tabsHans Goudey
This patch enables property search for all tabs in the property editor. To make interaction faster, if the editor's current tab doesn't have a result, the current tab changes to the next tab that has a match. This patch implements basic code that only searches panels. While we could run the existing "single tab" property search for every tab, that would also do everything else related to the layout pass, which would be less efficient, and maybe more complicated to maintain. The search match status for every current tab of the property editor is stored in a runtime bitfield and them displayed later by dimming icons in the tab selector panel to the left. Using `BLI_bitmap` properly in the runtime struct required moving it to `buttons_intern.h` and adding a small API to access the search filter instead. To make sure the editor isn't influenced by anything that happens while building the layout for other tabs, most of the context is duplicated and the new search is run in the duplicated editor. Note that the tool settings tab works slightly different than the other tabs, so I've disabled searching it for this commit. That would be a relatively simple improvement, but would just require a bit of refactoring of existing code. Differential Revision: https://developer.blender.org/D8859
2020-10-13UI: Add highlight arguments to tab buttonsHans Goudey
This adds arguments to `uiLayout.prop_tabs_enum` and the C equivalent (`uiItemTabsEnumR_prop`) to gray out tabs based on a boolean array. For property search in multiple tabs, we need a way to show which tabs have a search result, but we still need to show which tab is active. Differential Revision: https://developer.blender.org/D8858

2020-10-12Volumes: reduce step and default of strength in Volume Displace modifierJacques Lucke
The strength has a high impact on performance. With the previous step and default one could easily and accidentally make Blender unusably slow, because of a too high displacement strength.

2020-10-09Volumes: lower minimal voxel size in Mesh to Volume modifierJacques Lucke
The 0.1 limit was too large. The issue with making it smaller is that one can easily crash blender by making it to small. To counteract this, the step has been reduced as well. A voxel size/amount of 0 disables the modifier.

2020-10-07Volumes: new Volume Displace modifierJacques Lucke
This modifier uses a 3D texture to displace a volume. For now, this can only use the previously existing texture system, because we do not have a better alternative yet.

2020-10-07UV/Image Editor: Overlay PopoverJeroen Bakker
The overlay options in the image/uv editor is hidden in side panels and menus. Sometimes this panel is even hidden, while still useful. The goal of this task is to introduce an overlay pop-over just like the overlay-popover of the 3d viewport. Popover has * UV Stretching (only available in the UV mode, when active object mode is a mesh and in OB_EDIT mode) * Display As (only available in the UV mode, when active object mode is a mesh and in OB_EDIT mode) * Show Modified (only available in the UV mode, when active object mode is a mesh and in OB_EDIT mode) * Show UV Edges (including opacity slider; available UV, View, Paint, when active object mode is a mesh and in OB_EDIT mode) * Udim tiles when no image is available. Like the 3d viewport, there will be a editor toggle to enable/disable the overlays For compatibility reasons the RNA properties are added to both the `SpaceImage.uv_editor` amd `SpaceImage.overlay`. On DNA level they are still stored in the SpaceImage. only new properties are added to the SpaceImageOverlay struct. During the next major release we could remove these options from `SpaceImage.uv_editor`. This should be noted in the Python section of release notes.

2020-10-07Fix T76595: Indicate the Active Keyframe in Graph EditorHans Goudey
In the graph editor there is a panel that says "Active Keyframe" for numerically editing a keyframe's values, but in the code there is no concept of the "active keyframe." Since this is a useful concept to have for some other features anyway, this commit adds an active keyframe index value to FCurves. It also displays it with a theme color for the active vertex (which didn't exist before) if the FCurve is active. The active keyframe in the graph editor is treated similarly to the active vertex in the 3D view. It is the keyframe most recently selected with a single click, and it is always selected. For now, the only real functional change is that the active keyframe appears in white and it should be more predictable which keyframe is being edited in the sidebar panel.

2020-10-02UI: Improve UV sticky select mode descriptionHans Goudey
The sticky_select_mode property is an enum where each item has a different behavior, but currently the description is for a single one of the items. It should be more general, especially because one of the items is "Disabled." A couple more problems: - "Automatically" is not so helpful. Many things any program does are "automatic", it doesn't really help to say it. - "Also" is bad grammar. - Overly complex wording This also adjusts the SHARED_VERTEX tooltip, because "irrespective" should have "of" after, but it's also unecessarily complex.
