2021-02-04LibOverride: Improve/Fix issues in override resync process.Bastien Montagne
When we have a local override, its linked reference may not be detected as needing to be overridden anymore. In that case, if there is no actual override defined by the user, assume that we can get rid of this local override as part of the resync process, and use the linked data directly instead.

2021-02-04NLA: Extract nlasnapshot_blend()Wayde Moss
Refactor //nlastrip_evaluate_actionclip()// and //nlaeval_blend_value()// into //nlasnapshot_blend()//, //nlastrip_evaluate_actionclip()//, //nlasnapshot_from_action()//. **Motivations**: * {T83615} Requires reading all pose bone fcurves before being able to apply pre-blend transforms. The function //nlasnapshot_from_action()// achieves this. This effectively removed the need to specially handle Quaternion blend queuing so that code has been removed. * {D8296} Adds support for keyframe remapping through an upper stack of strips. Instead of introducing a variant of the form: //nlastrip_evaluate_actionclip_inverted_get_lower()//, //nlastrip_evaluate_actionclip()// will later be extended to take an `evaluation_mode` as input to avoid duplicating the recursion functions related to //nlastrip_evaluate()//. * //nlasnapshot_blend()// will eventually have variants of //nlasnapshot_blend_get_inverted_lower_snapshot()// and //nlasnapshot_blend_get_inverted_upper_snapshot()// which are all independent of NlaStrips and NlaTracks, further simplifying the blending implementation. Ideally, //nlastrip_evaluate()// would get renamed to //nlasnapshot_blend_strip()// but that'll be a later patch to avoid unnecessary patches slowing the review of more important patches.

2021-02-03Geometry Nodes: Multi-Input SocketsFabian Schempp
Normally sockets only have one input link. This commit adds the back-end changes needed to use multiple input links per socket. Multi-input sockets can be defined with a new flag in `bNodeSocketType`. The changes necessary to make the sockets work in the geometry nodes evaluator are generalizing input socket values as a vector of values, and supporting this in the derived node tree structure. This patch should contain no functional changes. Two upcoming patches will use this system for the "Join Geometry" node and expose link picking and updated display in the UI: D10069 and D10181.

2021-02-03Fix incorrect mesh selection duplication in internal utility functionJulian Eisel
`BKE_mesh_new_nomain_from_template_ex()` would duplicate the mesh selection storage of the destination mesh to the destination mesh. Since that mesh was default initialized at this point, the selection was `NULL`, so the duplication call is essentially a no-op. Mistake in 7efc75c7092b.

2021-02-03BKE UndoSys refactor: deduplicate and simplify code, sanitize naming.Bastien Montagne
Now we only use 'undo' or 'redo' in function names when the direction is clear (and we assert about it). Otherwise, use 'load' instead. When passing an undo step to BKE functions, consider calling code has done its work and is actually passing the target step (i.e. the final step intended to be loaded), instead of assuming we have to load the step before/after it. Also deduplicate and simplify a lot of core undo code in BKE, now `BKE_undosys_step_load_data_ex` is the only place where all the complex logic of undo/redo loop (to handle several steps in a row) is placed. We also only use a single loop there, instead of the two existing ones in previous code. Note that here we consider that when we are loading the current active step, we are undoing. This makes sense in that doing so //may// undo some changes (ideally it should never do so), but should never, ever redo anything. `BKE_undosys_step_load_from_index` also gets heavily simplified, it's not basically a shallow wrapper around `BKE_undosys_step_load_from_index`. And some general update of variable names, commenting, etc. Part of T83806. Differential Revision: https://developer.blender.org/D10227
2021-02-02Force Fields: implement early filtering by the Affect flags.Alexander Gavrilov
Most fields have Affect Location and Rotation options that switch off their effect, but they are only checked as the last step after the force is already computed. It is more efficient to check it when building the list of field objects, just like zero weight. It is also possible to check the strength-related fields for 0. As an aside, this adds Location to Texture fields (they don't handle rotation) and both Location & Rotation checkboxes to Fluid Flow. Boid and Curve Guide remain without options for now as they are completely different from others. Differential Revision: https://developer.blender.org/D10087

2021-02-02Fix T85155: Vertex groups from object don't transfer to next nodes modifierHans Goudey
Because the the vertex group name-to-index map is stored in the object rather than object data, the object info node has to replace the map when it replaces the mesh component on the geometry set with mesh data from another object. This normally works fine as a way to use the vertex groups from the input mesh, but when passing this mesh to the next modifier, the entire mesh component was replaced, removing the vertex group name map. This commit adds a function to replace only the mesh data in mesh component, uses it in the modifier code, and updates the relevant comments. Note that the fact that vertex group names are stored in object data is a legacy design decision that should be reevaluated at some point. Differential Revision: https://developer.blender.org/D10256

2021-01-29Fix T84717: missing 3D viewport updates when changing shading settingsBrecht Van Lommel
Previously this relied on the dependency graph to detect changes in the screen datablock, which would then notify the renderers. This was rather indirect an not even really by design. Instead use notifiers to tag specific 3D viewports to be updated. Includes changes to BKE_scene_get_depsgraph to accept a const Scene pointer. Testing if this works correctly requires adding back commits 81d444c and 088904d, since those have been temporarily reverted. Differential Revision: https://developer.blender.org/D10235

This improves the fix introduced in rBdc8b31af578bfcf9f77dbce6d7b7da1006a3c8c1.

2021-01-26Fix T84935: boolean custom data layers not saved correctlyJacques Lucke
The issue was that boolean custom data layers were not written to files, because the dna struct name `bool` does not exist. Adding a struct that just contains a `bool/uint8_t` does not seem to be possible, it looks like the minimum dna struct size is 4 bytes. The proposed solution has two parts: 1. Write the custom data layer using `BLO_write_raw` instead of `BLO_write_struct_array_by_name`. 2. When loading a file, reinitialize any custom data layer that was not saved correctly (this is just a fix for existing files). Differential Revision: https://developer.blender.org/D10194
