2019-12-12Add support for tiled images and the UDIM naming schemeLukas Stockner
This patch contains the work that I did during my week at the Code Quest - adding support for tiled images to Blender. With this patch, images now contain a list of tiles. By default, this just contains one tile, but if the source type is set to Tiled, the user can add additional tiles. When acquiring an ImBuf, the tile to be loaded is specified in the ImageUser. Therefore, code that is not yet aware of tiles will just access the default tile as usual. The filenames of the additional tiles are derived from the original filename according to the UDIM naming scheme - the filename contains an index that is calculated as (1001 + 10*<y coordinate of the tile> + <x coordinate of the tile>), where the x coordinate never goes above 9. Internally, the various tiles are stored in a cache just like sequences. When acquired for the first time, the code will try to load the corresponding file from disk. Alternatively, a new operator can be used to initialize the tile similar to the New Image operator. The following features are supported so far: - Automatic detection and loading of all tiles when opening the first tile (1001) - Saving all tiles - Adding and removing tiles - Filling tiles with generated images - Drawing all tiles in the Image Editor - Viewing a tiled grid even if no image is selected - Rendering tiled images in Eevee - Rendering tiled images in Cycles (in SVM mode) - Automatically skipping loading of unused tiles in Cycles - 2D texture painting (also across tiles) - 3D texture painting (also across tiles, only limitation: individual faces can not cross tile borders) - Assigning custom labels to individual tiles (drawn in the Image Editor instead of the ID) - Different resolutions between tiles There still are some missing features that will be added later (see T72390): - Workbench engine support - Packing/Unpacking support - Baking support - Cycles OSL support - many other Blender features that rely on images Thanks to Brecht for the review and to all who tested the intermediate versions!

2019-12-09Fix T72145: Object.update_from_editmode crashes with emptiesCampbell Barton
Also corrects the return value, where objects that don't have an edit-mode returned true, making it seem as if object data was flushed.

This was an old bug which could be caused by saving after separating. Changes from 79b703bb635e made this fail reliably. Update shape key indices when they may be used again later.

2019-11-21Tool System: make smooth & randomize modal operatorsCampbell Barton
Previously these used a gizmo to redo the operator however this complicated having on-screen gizmos to access tools (see T66304). Replace this with a generic way to make an operator that only has an execute function into a modal operator. This is used for smooth and randomize tools. Unlike operator gestures, this handles storing and resetting the data. Currently this only handles edit-mode data, however it's can be extended to other kinds of data.

2019-10-09Local Collections: Allow users to show hidden collectionsDalai Felinto
Users now can turn on in a viewport collections that are temporarily hidden (eye) in the view layer. Design task: T61327 As for the implementation, I had to decouple the visibility in the depsgraph from the visibility in the view layer. Also there is a "bug" that in a way was there before which is some operators (e.g., writing a text inside of a text object, tab into edit mode) run regardless of the visibility of the active object. The bug was present already (with object type visibility restriction) in 2.80 so if we decide to tackle it, can be done separately (I have a patch for it though P1132).

Quadriflow does not support non manifold meshes. (Edges with > 3 connected faces and discontinuous face normal directions) While it does sometimes "work" in these configurations, the results are not good and in most cases it just flat out will crash.

2019-10-01Fix T66641: Certain drivers fail to copy when copying a full scene.Bastien Montagne
The core of the issue here is that 'make single user' functions still does its own, manual and quite partial, remapping of IDs, which covers all most common cases but cannot consider *all* possible ID usages (especially when it comes to drivers or custom properties, that can essentially point to any kind of data-blocks). This fix is merely a band-aid, there is no way to fully solve this without a complete rewrite of that area of code to make use of modern ID management code.

This patch adds paint symmetry support to Quadriflow. It bisects and mirrors the input and the output from the remesher to build the final mesh using the preserve boundary option.

2019-09-26Voxel Remesh: Fix poles and preserve volumePablo Dobarro
This commit fixes most of the issues we currently have in the voxel remesher. Mesh volume is preserved when doing multiple iterations, so the sculpt won't shrink and smooth each time you run the remesher. Mesh topology is much better, fixing most issues related to mask extraction and other topology based operations. Reviewed By: jbakker Differential Revision: https://developer.blender.org/D5863

Particularly noticeable when vertex painting with a subsurf modifier. In some cases every sculpt or paint stroke step would evaluate the dependency graph. This should only happen for redraws. Now more selectively choose if the dependency graph should be evaluated to initialize the view context. Doing it in the view context evaluation is somewhat hidden, now it's more explicit.

2019-09-18Fix segfault when polling OBJECT_OT_voxel_remesh without active objectSybren A. Stüvel

2019-09-16Fix T64238: Scene Full Copy: Cameras bound to markers does not update.Bastien Montagne
That's exactly why we should get rid of all those 'custom cases' remapping code, it's hard enough to keep a single place (library_query.c) up to date and 100% valid, but having more areas doing their own remapping is just impossible to maintain... Some day...

2019-09-13Per-Viewport Collection VisibilityDalai Felinto
Support per-viewport collection visibility options. Note 1: There is no way to show a collection that was not visible before due to depsgraph. Otherwise we would risk having all the collections in the depsgraph and I believe this is not the idea. An alternative would be to have a new depsgraph for viewports that are not local. Something to keep in mind if we do per-viewport current frame in the future. So for now what we do is to only allow collections visibility to be disabled/hidden in this mode. Note 2: hide_viewport (the eye icon) doesn't really matter for depsgraph. So after the merge we can still ignore it to show the collections locally in a viewport with no problems for the depsgraph.
