Similar to the Principled BSDF, this should make it easier to set up volume
materials. Smoke and fire can be rendererd with just a single principled
volume node, the appropriate attributes will be used when available. The node
also works for simpler homogeneous volumes like water or mist.

This adds midlevel and object/world space for displacement, and a
vector displacement node with tangent/object/world space, midlevel
and scale.
Note that tangent space vector displacement still is not exactly
compatible with maps created by other software, this will require
changes to the tangent computation.

This converts object space height to world space displacement, to be
linked to the new vector displacement material output.

This would lead to sock.default_value pointing to the wrong data type,
possibly causing crashes. Unfortunately, this bug will still exist for
older Blender versions that try to load newer files, which makes
changing the type of a node socket problematic.

The RenderResult struct still has a listbase of RenderLayer, but that's ok
since this is strictly for rendering.
* Subversion bump (to 2.80.2)
* DNA low level doversion (renames) - only for .blend created since 2.80 started
Note: We can't use DNA_struct_elem_find or get file version in init_structDNA,
so we are manually iterating over the array of the SDNA elements instead.
Note 2: This doversion change with renames can be reverted in a few months. But
so far it's required for 2.8 files created between October 2016 and now.

This patch moves all the functionality previously in SceneRenderLayer to SceneLayer.
If we want to rename some of these structs now would be a good time to do it, before they are in SceneLayer.
Everything should be working, though I will test things further tomorrow. Once this is committed depsgraph can get
rid of the workaround added in rna_Main_meshes_new_from_object and finish whatever this patch was preventing from being finished.
This patch also adds a few placeholders for the overrides (samples, ...). These are obviously not working, so some unittests that rely on 'lay', and 'zmask' will fail.
This patch does not addressed the change of moving samples to ViewRender (I have this as a separate patch and needs some separate discussion).
Following next is the individual note of the individual parts that were committed.
Note 1: It is up to Cycles to still get rid of exclude_layer internally.
Note 2: Cycles still need to handle its own doversion for the use_layer_samples cases and
(1) Remove the override as it is
(2) Add a new override (scene.cycles.samples) if scene.cycles.use_layer_samples != IGNORE
Respecting the expected behaviour when scene.cycles.use_layer_samples == BOUNDED.
Note 3: Cycles still need to implement the per-object holdout
(similar to how we do shadow catcher).
Note 4: There are parts of the old (Blender Internal) rendering pipeline that is still
using lay, e.g., in shi->lay.
Honestly it will be easier to purge the entire Blender Internal code away instead of taking things from it bit by bit.

The algorithm averages normals from nearby surfaces. It uses the same
sampling strategy as BSSRDFs, casting rays along the normal and two
orthogonal axes, and combining the samples with MIS.
The main concern here is that we are introducing raytracing inside
shader evaluation, which could be quite bad for GPU performance and
stack memory usage. In practice it doesn't seem so bad though.
Note that using this feature can easily slow down renders 20%, and
that if you care about performance then it's better to use a bevel
modifier. Mainly this is useful for baking, and for cases where the
mesh topology makes it difficult for the bevel modifier to work well.

This let us know efficiently if a material has a dedicated nodetree for each of it's output node input.
Only works for Eevee at this moment.

Engine is not stored in WorkSpaces. That defines the "context" engine, which
is used for the entire UI.
The engine used for the poll of nodes (add node menu, new nodes when "Use Nodes")
is obtained from context.
Introduce a ViewRender struct for viewport settings that are defined for
workspaces and scene. This struct will be populated with the hand-picked
settings that can be defined per workspace as per the 2.8 design.
* use_scene_settings
* properties editor: workshop + organize context path
Use Scene Settings
==================
For viewport drawing, Workspaces have an option to use the Scene render
settings (F12) instead of the viewport settings.
This way users can quickly preview the final render settings, engine and
View Layer. This will affect all the editors in that workspace, and it will be
clearly indicated in the top-bar.
Properties Editor: Add Workspace and organize context path
==========================================================
We now have the properties of:
Scene, Scene > Layer, Scene > World, Workspace
[Scene | Workspace] > Render Layer > Object
[Scene | Workspace] > Render Layer > Object > Data

NODE_NEWER_SHADING was introduced in e868b459bb8e however it should have been
added as a bitflag.
BKE_scene_uses_blender_eevee() was used in gpu_shader_output() as a workaround
for compatibility being poorly used.
Anyways this fixes this situation. This is necessary for an upcoming patch, even
though this is considered temporary - since the other NODE_*_SHADING values are
legacy from Blender Internal drawing.

The is following: split copy on write update for node trees, and if we are only
tagging for uniform buffer update we skip whole datablock copy and only invoke
copy default_values form original nodetree to a copied one.
Thing which i'm not sure is: whether we need to use different branches in graph
itself to control such a conditional behavior, or whether we need to store tag
somewhere in the dependency graph. There are obviously cons and pros in both
approaches, and need to think about this. Maybe with more examples it becomes
more obvious which way is better.
This only fixes manual tweaks for now, animation support is coming.

The trees should match in nodes layout completely.
|
|
And wipe metallic out of the map.
|
|
Since we started supporting the (Cycles) Material Output old files
stopped working. There is no reason to keep the original Eevee material
otuput anymore.
It includes doversion for old files.

This will allow much finer controll over how we copy data-blocks, from
full copy in Main database, to "lighter" ones (out of Main, inside an
already allocated datablock, etc.).
This commit also transfers a llot of what was previously handled by
per-ID-type custom code to generic ID handling code in BKE_library.
Hopefully will avoid in future inconsistencies and missing bits we had
all over the codebase in the past.
It also adds missing copying handling for a few types, most notably
Scene (which where using a fully customized handling previously).
Note that the type of allocation used during copying (regular in Main,
allocated but outside of Main, or not allocated by ID handling code at
all) is stored in ID's, which allows to handle them correctly when
freeing. This needs to be taken care of with caution when doing 'weird'
unusual things with ID copying and/or allocation!
As a final note, while rather noisy, this commit will hopefully not
break too much existing branches, old 'API' has been kept for the main
part, as a wrapper around new code. Cleaning it up will happen later.

This makes the node menus aware of the Cycles/Eevee distinction, and
only show the relevant nodes for the current engine. Names have also
been changed to accomodate for the new output node system.
|
|
This makes Eevee consistent with Cycles, by having a single output node,
and multiple shader nodes that connect to it.
Note that node systems for Eevee saved before this will be missing the
output node, and thus will show an invalid material. This is easily
resolved by connecting the shader output to a new output node.

Noisy change, but safe, and better do it sooner than later if we are to
rework copying code. Also, previous commit shows this *is* useful to
catch some mistakes.

Previously, every RenderPass would have a bitfield that specified its type. That limits the number of passes to 32, which was reached a while ago.
However, most of the code already supported arbitrary RenderPasses since they were also used to store Multilayer EXR images.
Therefore, this commit completely removes the passflag from RenderPass and changes all code to use the unique pass name for identification.
Since Blender Internal relies on hardcoded passes and to preserve compatibility, 32 pass names are reserved for the old hardcoded passes.
To support these arbitrary passes, the Render Result compositor node now adds dynamic sockets. For compatibility, the old hardcoded sockets are always stored and just hidden when the corresponding pass isn't available.
To use these changes, the Render Engine API now includes a function that allows render engines to add arbitrary passes to the render result. To be able to add options for these passes, addons can now add their own properties to SceneRenderLayers.
To keep the compositor input node updated, render engine plugins have to implement a callback that registers all the passes that will be generated.
From a user perspective, nothing should change with this commit.

In the "GGX" mode there is an additional parameter for changing the

(e.g. honey). With the "Multiscatter GGX" this effect can't be produced at
the moment and so here will be no separation of the two roughness values.

Added a roughness parameter for refractions (for scattering of the rays
within an object)
With this, one can create a translucent material with a smooth surface and
with a milky look.
The final refraction roughness has to be calculated using the surface
roughness and the refraction roughness because those two are correlated
for refractions. If a ray hits a rough surface of a translucent material,
it is scattered while entering the surface. Then it is scattered further
within the object. The calculation I'm using is the following:
RefrRoughnessFinal = 1.0 - (1.0 - Roughness) * (1.0 - RefrRoughness)

64 outputs
Ideally we need to find a way to remove such a static limit here, but it's not so
trivial to implement for texture nodes. Requires some bigger system redesign there.
Just raising limit for now, which is fine for modern systems.

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.

BKE_libblock_relink_ex instead.

Turns out most BKE_foo_make_local datablock-specific functions are actually doing
exactly the same thing, only two currently need special additional operations
(object and brush ones). So added a BKE_id_make_local_generic instead
of copying same code over and over.
Also, changed a bit how make_local works in case we are localizing a whole library.
We need to do the 'remap' step (from old linked ID to new local one) in the second loop,
otherwise we miss some dependencies. This fixes main part of T48907.

handling).
This commit changes a lot of how IDs are handled internally, especially the unlinking/freeing
processes. So far, this was very fuzy, to summarize cleanly deleting or replacing a datablock
was pretty much impossible, except for a few special cases.
Also, unlinking was handled by each datatype, in a rather messy and prone-to-errors way (quite
a few ID usages were missed or wrongly handled that way).
One of the main goal of id-remap branch was to cleanup this, and fatorize ID links handling
by using library_query utils to allow generic handling of those, which is now the case
(now, generic ID links handling is only "knwon" from readfile.c and library_query.c).
This commit also adds backends to allow live replacement and deletion of datablocks in Blender
(so-called 'remapping' process, where we replace all usages of a given ID pointer by a new one,
or NULL one in case of unlinking).
This will allow nice new features, like ability to easily reload or relocate libraries, real immediate
deletion of datablocks in blender, replacement of one datablock by another, etc.
Some of those are for next commits.
A word of warning: this commit is highly risky, because it affects potentially a lot in Blender core.
Though it was tested rather deeply, being totally impossible to check all possible ID usage cases,
it's likely there are some remaining issues and bugs in new code... Please report them! ;)

material use node groups

Was missing id macro variable.

Nodes have a feature for moving existing links to unoccupied sockets when connecting
to an already used input. This is based on the standard legacy socket types (value/float,
vector, color/rgba) and works reasonably well for shader, compositor and texture nodes.
For new pynode systems, however, the hardcoded nature of that feature has major drawbacks:
* It does not take different type systems into account, leading to meaningless connections
when sockets are swapped and making the feature useless or outright debilitating.
* Advanced socket behaviors would be possible with a registerable callback, e.g. creating
extensible input lists that move existing connections down to make room for a new link.
Now any handling of new links is done via the 'insert_links' callback, which can also be
registered through the RNA API. For the legacy shader/compo/tex nodes the behavior is the
same, using a C callback.
Note on the 'use_swap' flag: this has been removed because it was meaningless anyway:
It was disabled only for the insert-node-on-link feature, which works only for
completely unconnected nodes anyway, so there would be nothing to swap in the first place.

Idea is, instead of ignoring completely missing linked datablocks, to
create void placeholders for them.
That way, you can work on your file, save it, and find again your missing data once
lib becomes available again. Or you can edit missing lib's path (in Outliner),
save and reload the file, and you are done.
Also, Outliner now shows broken libraries (and placeholders) with a 'broken lib' icon.
Future plans are also to be able to relocate missing libs and reload them at runtime.
Code notes:
- Placeholder ID is just a regular datablock of same type as expected linked one,
with 'default' data, and a LIB_MISSING bitflag set.
- To allow creation of such datablocks, creation of datablocks in BKE was split in two step:
+ Allocation of memory itself.
+ Setting of all internal data to default values.
See also the design task (T43351).
