2020-12-16Fix T83851: Python: operator macros cause a crashPhilipp Oeser
Caused by rB7447eb7e7430. This is just a copy-paste error [previous LISTBASE_FOREACH substitution of marco loop in that file has a different starting point which is not appropriate here] Maniphest Tasks: T83851 Differential Revision: https://developer.blender.org/D9872
2020-12-16Geometry Nodes: Poisson disk point distribution node/methodDalai Felinto
This patch does two things: * Introduce a Seed to the random distribution method * Bring in a new distribution method for the point scattering node Patch Review: https://developer.blender.org/D9787 Note: This commit doesn't not handle doversion. Which means that users need to manually update their files that were using the Point Distribute node and reconnect inputs to the "Maximum Density" socket. Original patch by Sebastian Parborg, with changes to not rely on the cy libraries and overall cleanup. Patch review by Jacques Lucke, besides help with the new "heap" system that was required for this algorithm. Based on Cem Yuksel. 2015. Sample Elimination for Generating Poisson Disk Sample. Sets.

2020-12-16Sculpt: Multires Displacement SmearPablo Dobarro
This tool implements smearing for multires displacement over the limit surface, similar to how smearing for colors and topology slide works. When used the displacement values of the vertices "slide" over the topology, creating the effect of smearing the surface detail. As the brush just modifies displacement values instead of coordinates, the total displacement of the affected area doesn't change. This means that this smearing effect can be used multiple times over the same area without generating any artifacts in the topology. When the brush is used with the pinch or expand smear modes, displacement differences are pushed into the same area, creating hard surface effects without pinching the topology. As any other brush that relies on the limit surface (like displacement erasers), this will work better after using apply base.

2020-12-16Asset Browser: For assets without preview, show type icon in sidebarJulian Eisel
Otherwise it would just show empty space where the icon is supposed to be. Unfortunately this icon is upscaled quite a bit and doesn't look too great. Would be good to improve but not a high priority.

No icon should be created if the preview doesn't exist.
2020-12-16BLI: remove implicit casts between some span typesJacques Lucke
Casting pointers from one type to another does change the value of the pointer in some cases. Therefore, casting a span that contains pointers of one type to a span that contains pointers of another type, is not generally safe. In practice, this issue mainly comes up when dealing with classes that have a vtable. There are some special cases that are still allowed. For example, adding const to the pointer does not change the address. Also, casting to a void pointer is fine. In cases where implicit conversion is disabled, but one is sure that the cast is valid, an explicit call of `span.cast<NewType>()` can be used.

When doing a debug build on windows, blender will start with the following warning: "Unable to find the python binary, the multiprocessing module may not be functional!" The root cause for this issue is: for a debug build the python binary is called python_d.exe rather than just python.exe This change fixes BKE_appdir_program_python_search to look for the _d suffix for debug builds on windows Differential Revision: https://developer.blender.org/D9775 Reviewed by: Campbell Barton
2020-12-16LibOverride: Better handling of missing linked data during resync.Bastien Montagne
We do not generate overrides for missing data-blocks (aka placeholder ones) anymore, and properly delete the remaining old overrides of those during the resync process. This should prevent constant 'missing data-blocks' messages when opening blend files with overrides whose libraries have beed edited. Issue reported by @andy from Blender studio, thanks.
2020-12-16Fix T83801: UVEditor translation ignores "Pixel Coordinates" and aspectPhilipp Oeser
ratio Caused by rB4eda60c2d82d. T83801 reported not moving in pixel space, but even without that toggle above commit caused the translation to not take apsect ratio into account properly [a translation of 1 on the x axis for example on an image with non 1:1 aspect ration caused the UVs to not end up in the same place on the next 'tile'] Above commit removed 'removeAspectRatio()' [the counterpart of applyAspectRatio -- which does the pixel coord correction internally] from 'applyTranslation()'. This was also reported in T83352 [which was closed by rBf3b08af24c9f -- but that only solved the displax in header, not the actual transformation] Now bring back 'removeAspectRatio()'.

2020-12-16Fix 3D View is red when using stereoValdemar Lindberg
Fix T83415: 3D View is red when using stereo The red view was caused by SRGB not being enabled for an SRGB texture attached to the framebuffer. Currently, when configuring a framebuffer, the first texture attachment needs to be an SRGB format in order for the framebuffer to be binded with SRGB enabled. Thus, simply changing the SRGB texture attachment as the first texture attachment removes the red color in the view.

2020-12-16Fix T83557: Alpha blend + emissive colors renders white artifactsJeroen Bakker
Issue was that not all code paths were taken to determine if the GPU Texture was premultiplied or not. In this case the result was set to unpremultiplied what is incorrect. This fixes broken test case image alpha blend from image_colorspace.

Previously, the node was called Random Attribute. For consistency reasons, we move the "Attribute" part of the name to the front.
2020-12-16BLI: add new InplacePriorityQueue data structureJacques Lucke
This data structure adds priority queue functionality to an existing array. The underlying array is not changed. Instead, the priority queue maintains indices into the original array. Changing priorities of elements dynamically is supported, but the priority queue has to be informed of such changes. This data structure is needed for D9787.
2020-12-16Fix possible crash with custom (add-on defined) iconsEric Cosky

2020-12-16UI: Indicate asset data-blocks with an icon in Outliners & search menusJulian Eisel
It's useful to easily see which data-blocks are assets and which not. So just like we usually show the library linking/override icons, we show the asset icon there (these are mutually exclusive data-block states). Uses the `'MAT_SPHERE_SKY` icon, which wasn't used before (except by an add-on!) and is sorta fitting, but not quite. We should either change this one or add an own asset icon. Meanwhile this isn't too bad :) Also adds an internal macro to check if a data-block is an asset, consistent to how we do it for libraries and library overrides.
2020-12-16Assets: Add operator & button to regenerate the automatic previewJulian Eisel
This makes it possible to trigger a refresh of the data-block preview, available next to the preview in the Asset Browser sidebar. The previews get easily outdated and automatically refreshing it all the time is not an option because it would be a consistently running, quite expensive process. So a button to cause a refresh should be reasonable. This button can also be used to switch back from a custom preview to a generated one. Although that may not be clear, and we should probably think of a way to explain that better. Addresses T82719.

2020-12-15Fix various issues with temporary, maximized File BrowsersJulian Eisel
If Preferences > Interface > Temporary Editors > File Browser is set to "Maximized Area", opening a File Browser from a File or Asset Browser as regular editor would cause some issues. For example after closing the temporary File Browser, the regular browser would take over the file path and display settings from the temporary one. This is because they used to share the same area data. Some similar issues may have happend with temporary image editors. Now, this commit finally separates the space data of temporary maximized editors from the regular ones. So the editor data is entirely independent now, as it should be.
2020-12-15Sculpt: Fair Face Sets operation for Face Set EditPablo Dobarro
This implements a mesh fairing algorithm and implements the fair operations for Face Set edit. This edit operations create a smooth as possible geometry patch in the area of the selected Face Set. The mesh fairing algorithm is designed by Brett Fedack for the addon "Mesh Fairing": https://github.com/fedackb/mesh-fairing, with some modifications: - The main fairing function in BKE_mesh_fair.h does not triangulate the mesh. For the test I did in sculpt mode results are good enough without triangulating the topology. Depending on the use and the result quality needed for a particular tool, the mesh can be triangulate in the affected area before starting fairing. - Cotangents loop weights are not implemented yet. The idea is to also expose the vertex and loop weights in a different function in case a tool needs to set up custom weights. This algorithm will also be used to solve the limitations of line project and implement the Lasso Project and Polyline Project tools. It can also be used in tools in other areas of Blender, like Edit Mode or future retopology tools. Reviewed By: brecht Differential Revision: https://developer.blender.org/D9603

2020-12-15Fix Adjust Last Operation popup for operators relying on button contextPhilipp Oeser
This was reported for duplicating particle systems, then using F9 to enable the 'Duplicate Settings' option (see T83317). In this case, the operator gets the particle_system from (buttons) context and if none can get found will duplicate all settings instead. The reason why none gets found here is that buttons_context() doesnt have a valid path when called from F9/SCREEN_OT_redo_last, path is cleared when global undo does a file-read which clears the path (see lib_link_workspace_layout_restore). It can be recomputed though to be valid even from redo_last (at least when in the Properties Editor). This was likely causing other operators (relying on buttons context) from the Properties Editor to fail as well.

2020-12-15Fix crash opening maximized File Browser from Asset BrowserJulian Eisel
If Preferences > Interface > Temporary Editors > File Browser is set to "Maximized Area", opening a File Browser from an Asset Browser would cause the new maximized editor to be an Asset Browser. Exiting it again would crash. This fixes the wrong behavior and the crash. There's still an issue with exiting the editor again, it stays a File Browser then and doesn't go back to being an Asset Browser. That's to be fixed separately.

`blf_dir_search` BLF util would not properly handle relative fonts not found in pre-defined 'system fonts' directoriesi stored in `global_font_dir` global variable. Now it rebases relative paths to current .blend file location as expected.

2020-12-15Fix crash when deleting/renaming asset library while it's visibleJulian Eisel
Storing the asset library reference by name wasn't a good idea, I thought it would work with a careful fallback, but it's easier to just use the index instead. So change to using indices, make sure fallback methods work reliable and make sure the file list is updated when asset libraries are removed. I added a new notifier type for the latter, I prefer not using file notifiers in asset-library/preferences code. We have more than enough values for notifiers left.

The `!BKE_previewimg_is_finished()` in `icon_preview_startjob_all_sizes()` would fail. Caused by 990bd9acf243ae. We have to be more picky about tagging previews as unfinished after file read. But we also have to consider files stored in old versions and set the unfinished tag as needed.
2020-12-15Fix Asset Browser crash with undo in "Current File" library with sidebarJulian Eisel
When the Asset Browser was showing the "Current File" repository and the sidebar was open, undoing could crash, because the context API returned freed data. Don't let context return anything if a refresh is pending due to data changes like undo/redo.
2020-12-15Assets: Better path for the default asset libraryJulian Eisel
In D9722 we agreed on using `[home-directory]/Documents/Blender/Assets` for the default asset library. I just forgot to do the change before committing. (The default repository is just a named path, it's *not* a default library with bundled assets.)
2020-12-15Fix asset previews not showing in "Current File" repository after readingJulian Eisel
Previews would be flagged as unfinished when reading. Instead clear the flag and always consider them finished upon reading. If we wouldn't do this, the File Browser would keep running the preview updating to wait for the preview to finish. It could be smarter and also check if there's actually a preview job running. Instead, I think it will just display an unfilled buffer for now. Up until today we wouldn't even know if a stored preview is finished or not, so it would always assume they are finished. We do the same now, but have the option to make it smarter.
2020-12-15Asset System: New Asset Browser editorJulian Eisel
This introduces the User Interface part of the Asset Browser, based on the design in T54642. Additions: * New Asset Browser (internally a sub-editor of the File Browser). * Navigation region showing asset categories. * Main region showing the assets of the selected asset library with previews. The assets may be stored over multiple .blends in the directory that's "mounted" as asset library in the Preferences. They will all be shown in this list. * Header with an asset library dropdown, allowing to choose the active asset library to show. Options are the "Current File" as asset library and all custom libraries. * Display popover, filter popover and search box (partially dummies, see T82680). * Sidebar showing the metadata of the currently active file (name, preview, description and tags), which can be edited for assets in the "Current File" asset library. (For others it will reset on reload.) * The sidebar includes a button to load a custom preview image from a file. * Make asset files draggable (with preview image). * If a library with invalid path is selected, a message is drawn in the main region to help the user understand what's wrong. * Operators to add and remove asset tags. Exposed in the sidebar. * "Only Assets" option for Link/Append. * Internal utilities for asset UI scripts. For screenshots or demo videos, please see D9725. Or the 2.92 release notes. Note that there are many things to be tweaked and polished in the Asset Browser UI still. For example, the filter and display popovers are mostly dummies. See T82680.

See previous commit. **Space Data** * Introduce "browse mode" to differeniate between file and asset browsing. * Add `FileAssetSelectParams` to `SpaceFile`, with `FileSelectParams` as base. Makes sure data is separated between asset and file browsing when switching between them. The active params can be obtained through `ED_fileselect_get_active_params()`. * `FileAssetSelectParams` stores the currently visible asset library ID. * Introduce file history abstraction so file and asset browsing can keep a separate history (previous and next directories). **General** * Option to only show asset data-blocks while file browsing (not exposed here). * Add "active_file" context member, so scripts can get and display info about the active file. * Add "active_id" context member, so `ED_OT_lib_id_load_custom_preview` can set a custom ID preview. (Only for "Current File" asset library) * Expose some of `FileDirEntry` in RNA as (non-editable). That way scripts can obtain name, preview icon and asset-data.

2020-12-15Asset System: Support custom asset library paths through PreferencesJulian Eisel
One of the core design aspects of the Asset Browser is that users can "mount" custom asset libraries via the Preferences. Currently an asset library is just a directory with one or more .blend files in it. We could easily support a single .blend file as asset library as well (rather than a directory). It's just disabled currently. Note that in earlier designs, asset libraries were called repositories. Idea is simple: In Preferences > File Paths, you can create custom libraries, by setting a name and selecting a path. The name is ensured to be unique. If the name or path are empty, the Asset Browser will not show it in the list of available asset libraries. The library path is not checked for validity, the Asset Browser will allow selecting invalid libraries, but show a message instead of the file list, to help the user understand what's going on. Of course the actual Asset Browser UI is not part of this commit, it's in one of the following ones. {F9497950} Part of the first Asset Browser milestone.
