Differential Revision: https://developer.blender.org/D9861 Ref T82585.
2020-12-16VSE: Improve motion-picture workflowRichard Antalik
This commit resolves problem introduced in e1665c3d3190 - it was difficult to import media at their original resolution. This is done by using original resolution as reference for scale. All crop and strip transform values and their animation is converted form old files. To make both workflows easy to use, sequencer tool settings have been created with preset for preffered scaling method. This setting is in sequencer timeline header and add image or movie strip operator properties. Two new operators have been added: `sequencer.strip_transform_fit` operator with 3 options: Scale To Fit, Scale to Fill and Stretch To Fill. Operator can fail if strip image or video is not loaded currently, this case should be either sanitized or data loaded on demand. `sequencer.strip_transform_clear` operator with 4 options: Clear position, scale, rotation and all (previous 3 options combined).

2020-12-16Geometry Nodes: Boolean attribute typeHans Goudey
This adds a boolean attribute and custom data type, to be used in the point separate node. It also adds it as supported data types in the random attribute and attribute fill nodes. There are more clever ways of storing a boolean attribute that make more sense in certain situations-- sets, bitfields, and others, this commit keeps it simple, saving those changes for when there is a proper use case for them. In any case, we will still probably always want the idea of a boolean attribute. Differential Revision: https://developer.blender.org/D9818
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.

2020-12-16GPencil Array - Add option for uniform random scalingCody Winchester
This patch adds the option to make the random scaling from the grease pencil array modifier uniform. The current settings allow a separate value for each of the 3 scaling axis. The modifier also creates different seed values for each axis so there is no way to keep the random scaling uniform. This patch creates 1 random seed value and applies it to each of the scaling axis. Here is a demonstration of the previous behavior and the new optional behavior. {F9485973} {F9485981} {F9485798} Reviewed By: #grease_pencil, antoniov, pepeland Differential Revision: https://developer.blender.org/D9764
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.
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.

2020-12-15Asset System: Prepare File Browser backend for the Asset BrowserJulian Eisel
The Asset Browser will be a sub-editor of the File Browser. This prepares the File Browser code for that. **File-Lists** * Support loading assets with metadata read from external files into the file-list. * New main based file-list type, for the "Current File" asset library. * Refresh file-list when switching between browse modes or asset libraries. * Support empty file-lists (asset library with no assets). * Store file previews as icons, so scripts can reference them via icon-id. 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.

2020-12-15Asset System: "Mark Asset" & "Clear Asset" operators and UI integrationJulian Eisel
This makes it possible to turn data-blocks into assets and back into normal data-blocks. A core design decision made for the asset system is that not every data-block should be an asset, because not every data-block is made for reuse. Users have to explicitly mark data-blocks as assets. Exposes "Mark Asset" and "Clear Asset" in Outliner context menus (currently ID Data submenu) and button context menus. We are still not too happy with the names, they may change. This uses the new context members to pass data-blocks to operators, added in af008f553293 and 0c1d4769235c. Part of the first Asset Browser milestone.

2020-12-15Asset System: Data-block asset metadata storage, reading and APIJulian Eisel
Asset metadata is what turns a regular data-block into an asset. It is a small data-structure, but a key part of the technical design of the asset system. The design foresees that asset data-blocks store an `ID.asset_data` pointer of type `AssetMetaData`. This data **must not** have dependencies on other data-blocks or data-block data, it must be an independent unit. That way we can read asset-metadata from .blends without reading anything else from the file. The Asset Browser will use this metadata (together with the data-block name, preview and file path) to represent assets in the file list. Includes: * New `ID.asset_data` for asset metadata. * Asset tags, description and custom properties. * BKE code to manage asset meta-data and asset tags. * Code to read asset data from files, without reading IDs. * RNA for asset metadata (including tags) Part of the first Asset Browser milestone.

This changes the way how the mattes are stored in the compositor node. This used to be a single string what was decoded/encoded when needed. The new data structure stores all entries in `CryptomatteEntry` and is converted to the old `matte_id` property on the fly. This is done for some future changes in the workflow where a more structured approach leads to less confusing and easier to read code.

2020-12-09Modifier: Add "Connected" mode to the weld modifierHenrik Dick
Implement improvement from T73139 for merging along edges. It is now called "Connected" mode, while the default is called "All". With the recent performance improvement, the Connected Mode is in some cases only double the speed than the usual merge all strategy but in other cases it may be even faster. The bottleneck is somewhere further down the line of merging geometry. The motivation for this patch came from T80897, because the merging in complex solidify is making it very slow. Now merging can be removed from solidify without greater consequences, as this is just a quicker and more advanced algorithm to do the same thing that solidify currently does slowly.

2020-12-08File Browser: Refactor access to the selection parameters structJulian Eisel
* Avoid direct access to `SpaceFile.params`, use a getter instead. This matters because once the asset-browser changes are in, there will be an alternative selection parameter object. The getter can return the correct one. * Rename the function to ensure the parameters. The old name `ED_fileselect_get_params()` wasn't a mere getter, it would create the parameters if necessary. Now we have an actual getter, so better be clear. * In some instances, I replaced the old "get" function with the new mere getter. So the ensure logic is called less often. However, in these cases we should be able to assume the selection parameters were created already as part of the editor creation routine. The term "active" in the new function names may seem a bit odd in the current context, but that is a preparation for the Asset Browser merge as well. Like said, there will be two file selection parameter objects in the space.
