Collections and groups unification OVERVIEW * In 2.7 terminology, all layers and groups are now collection datablocks. * These collections are nestable, linkable, instanceable, overrideable, .. which opens up new ways to set up scenes and link + override data. * Viewport/render visibility and selectability are now a part of the collection and shared across all view layers and linkable. * View layers define which subset of the scene collection hierarchy is excluded for each. For many workflows one view layer can be used, these are more of an advanced feature now. OUTLINER * The outliner now has a "View Layer" display mode instead of "Collections", which can display the collections and/or objects in the view layer. * In this display mode, collections can be excluded with the right click menu. These will then be greyed out and their objects will be excluded. * To view collections not linked to any scene, the "Blender File" display mode can be used, with the new filtering option to just see Colleciton datablocks. * The outliner right click menus for collections and objects were reorganized. * Drag and drop still needs to be improved. Like before, dragging the icon or text gives different results, we'll unify this later. LINKING AND OVERRIDES * Collections can now be linked into the scene without creating an instance, with the link/append operator or from the collections view in the outliner. * Collections can get static overrides with the right click menu in the outliner, but this is rather unreliable and not clearly communicated at the moment. * We still need to improve the make override operator to turn collection instances into collections with overrides directly in the scene. PERFORMANCE * We tried to make performance not worse than before and improve it in some cases. The main thing that's still a bit slower is multiple scenes, we have to change the layer syncing to only updated affected scenes. * Collections keep a list of their parent collections for faster incremental updates in syncing and caching. * View layer bases are now in a object -> base hash to avoid quadratic time lookups internally and in API functions like visible_get(). VERSIONING * Compatibility with 2.7 files should be improved due to the new visibility controls. Of course users may not want to set up their scenes differently now to avoid having separate layers and groups. * Compatibility with 2.8 is mostly there, and was tested on Eevee demo and Hero files. There's a few things which are know to be not quite compatible, like nested layer collections inside groups. * The versioning code for 2.8 files is quite complicated, and isolated behind #ifdef so it can be removed at the end of the release cycle. KNOWN ISSUES * The G-key group operators in the 3D viewport were left mostly as is, they need to be modified still to fit better. * Same for the groups panel in the object properties. This needs to be updated still, or perhaps replaced by something better. * Collections must all have a unique name. Less restrictive namespacing is to be done later, we'll have to see how important this is as all objects within the collections must also have a unique name anyway. * Full scene copy and delete scene are exactly doing the right thing yet.

Collections and groups unification OVERVIEW * In 2.7 terminology, all layers and groups are now collection datablocks. * These collections are nestable, linkable, instanceable, overrideable, .. which opens up new ways to set up scenes and link + override data. * Viewport/render visibility and selectability are now a part of the collection and shared across all view layers and linkable. * View layers define which subset of the scene collection hierarchy is excluded for each. For many workflows one view layer can be used, these are more of an advanced feature now. OUTLINER * The outliner now has a "View Layer" display mode instead of "Collections", which can display the collections and/or objects in the view layer. * In this display mode, collections can be excluded with the right click menu. These will then be greyed out and their objects will be excluded. * To view collections not linked to any scene, the "Blender File" display mode can be used, with the new filtering option to just see Colleciton datablocks. * The outliner right click menus for collections and objects were reorganized. * Drag and drop still needs to be improved. Like before, dragging the icon or text gives different results, we'll unify this later. LINKING AND OVERRIDES * Collections can now be linked into the scene without creating an instance, with the link/append operator or from the collections view in the outliner. * Collections can get static overrides with the right click menu in the outliner, but this is rather unreliable and not clearly communicated at the moment. * We still need to improve the make override operator to turn collection instances into collections with overrides directly in the scene. PERFORMANCE * We tried to make performance not worse than before and improve it in some cases. The main thing that's still a bit slower is multiple scenes, we have to change the layer syncing to only updated affected scenes. * Collections keep a list of their parent collections for faster incremental updates in syncing and caching. * View layer bases are now in a object -> base hash to avoid quadratic time lookups internally and in API functions like visible_get(). VERSIONING * Compatibility with 2.7 files should be improved due to the new visibility controls. Of course users may not want to set up their scenes differently now to avoid having separate layers and groups. * Compatibility with 2.8 is mostly there, and was tested on Eevee demo and Hero files. There's a few things which are know to be not quite compatible, like nested layer collections inside groups. * The versioning code for 2.8 files is quite complicated, and isolated behind #ifdef so it can be removed at the end of the release cycle. KNOWN ISSUES * The G-key group operators in the 3D viewport were left mostly as is, they need to be modified still to fit better. * Same for the groups panel in the object properties. This needs to be updated still, or perhaps replaced by something better. * Collections must all have a unique name. Less restrictive namespacing is to be done later, we'll have to see how important this is as all objects within the collections must also have a unique name anyway. * Full scene copy and delete scene are exactly doing the right thing yet.

Render Layers and Collections (merge from render-layers) Design Documents ---------------- * https://wiki.blender.org/index.php/Dev:2.8/Source/Layers * https://wiki.blender.org/index.php/Dev:2.8/Source/DataDesignRevised User Commit Log --------------- * New Layer and Collection system to replace render layers and viewport layers. * A layer is a set of collections of objects (and their drawing options) required for specific tasks. * A collection is a set of objects, equivalent of the old layers in Blender. A collection can be shared across multiple layers. * All Scenes have a master collection that all other collections are children of. * New collection "context" tab (in Properties Editor) * New temporary viewport "collections" panel to control per-collection visibility Missing User Features --------------------- * Collection "Filter" Option to add objects based on their names * Collection Manager operators The existing buttons are placeholders * Collection Manager drawing The editor main region is empty * Collection Override * Per-Collection engine settings This will come as a separate commit, as part of the clay-engine branch Dev Commit Log -------------- * New DNA file (DNA_layer_types.h) with the new structs We are replacing Base by a new extended Base while keeping it backward compatible with some legacy settings (i.e., lay, flag_legacy). Renamed all Base to BaseLegacy to make it clear the areas of code that still need to be converted Note: manual changes were required on - deg_builder_nodes.h, rna_object.c, KX_Light.cpp * Unittesting for main syncronization requirements - read, write, add/copy/remove objects, copy scene, collection link/unlinking, context) * New Editor: Collection Manager Based on patch by Julian Eisel This is extracted from the layer-manager branch. With the following changes: - Renamed references of layer manager to collections manager - I doesn't include the editors/space_collections/ draw and util files - The drawing code itself will be implemented separately by Julian * Base / Object: A little note about them. Original Blender code would try to keep them in sync through the code, juggling flags back and forth. This will now be handled by Depsgraph, keeping Object and Bases more separated throughout the non-rendering code. Scene.base is being cleared in doversion, and the old viewport drawing code was poorly converted to use the new bases while the new viewport code doesn't get merged and replace the old one. Python API Changes ------------------ ``` - scene.layers + # no longer exists - scene.objects + scene.scene_layers.active.objects - scene.objects.active + scene.render_layers.active.objects.active - bpy.context.scene.objects.link() + bpy.context.scene_collection.objects.link() - bpy_extras.object_utils.object_data_add(context, obdata, operator=None, use_active_layer=True, name=None) + bpy_extras.object_utils.object_data_add(context, obdata, operator=None, name=None) - bpy.context.object.select + bpy.context.object.select = True + bpy.context.object.select = False + bpy.context.object.select_get() + bpy.context.object.select_set(action='SELECT') + bpy.context.object.select_set(action='DESELECT') -AddObjectHelper.layers + # no longer exists ```

Outliner Visibility Update See T61578 for discussions and mockups. Visibility Options ================== We are adding more granular control over restriction columns in the outliner, exposing "indirect only" and "holdout" as options, and change the way users enable/disable collections in a viewlayer. We also rename the object viewport restriction to hide instance. So the options we have are: Collection ---------- * Render Visibility * Instance Visibility * Selectable (View) Layer Collection ----------------------- * Enable * Holdout * Indirect Only * Viewport Shortcuts ========= Isolate Collection ------------------ * Ctr + click isolates the collection. It turns all its parents and children "visible", and all the other collections "invisible". If ALL the collections were already properly set, we re-set the collections to their default value. Set Collection Inside Collections and Objects --------------------------------------------- * Shift + click: Set/unset inside collections and objects. We only set objects values as well when we are in View Layer mode and (obviously) when the objects have a matching property. Icons ===== Little reminder that we will need better icons for holdout, indirect only, and probably instanced (nothing wrong with the current, but it differs from the proposal when it is turned off). Also, we need to decide where do we want the modifier/bones/... icons to be (in which column) and ideally make sure their icons match the ones we use for collections/objects. At the moment those are using the screen icon, which is not being used by collections. Reviewers: brecht, billrey Subscribers: pablovazquez Differential Revision: https://developer.blender.org/D4823

With the following changes: - Renamed references of layer manager to collections manager - I doesn't include the editors/space_collections/ draw and util files - The drawing code itself will be implemented separately by Julian * Base / Object: A little note about them. Original Blender code would try to keep them in sync through the code, juggling flags back and forth. This will now be handled by Depsgraph, keeping Object and Bases more separated throughout the non-rendering code.

A collection can be shared across multiple layers. * All Scenes have a master collection that all other collections are children of. * New collection "context" tab (in Properties Editor) * New temporary viewport "collections" panel to control per-collection visibility Missing User Features --------------------- * Collection "Filter" Option to add objects based on their names * Collection Manager operators The existing buttons are placeholders * Collection Manager drawing The editor main region is empty * Collection Override * Per-Collection engine settings This will come as a separate commit, as part of the clay-engine branch Dev Commit Log -------------- * New DNA file (DNA_layer_types.h) with the new structs We are replacing Base by a new extended Base while keeping it backward compatible with some legacy settings (i.e., lay, flag_legacy). Renamed all Base to BaseLegacy to make it clear the areas of code that still need to be converted Note: manual changes were required on - deg_builder_nodes.h, rna_object.c, KX_Light.cpp * Unittesting for main syncronization requirements - read, write, add/copy/remove objects, copy scene, collection link/unlinking, context) * New Editor: Collection Manager Based on patch by Julian Eisel This is extracted from the layer-manager branch. With the following changes: - Renamed references of layer manager to collections manager - I doesn't include the editors/space_collections/ draw and util files - The drawing code itself will be implemented separately by Julian * Base / Object: A little note about them. Original Blender code would try to keep them in sync through the code, juggling flags back and forth. This will now be handled by Depsgraph, keeping Object and Bases more separated throughout the non-rendering code. Scene.base is being cleared in doversion, and the old viewport drawing code was poorly converted to use the new bases while the new viewport code doesn't get merged and replace the old one.
