Pull Request #107849
This adds support for building simulations with geometry nodes. A new
`Simulation Input` and `Simulation Output` node allow maintaining a
simulation state across multiple frames. Together these two nodes form
a `simulation zone` which contains all the nodes that update the simulation
state from one frame to the next.
A new simulation zone can be added via the menu
(`Simulation > Simulation Zone`) or with the node add search.
The simulation state contains a geometry by default. However, it is possible
to add multiple geometry sockets as well as other socket types. Currently,
field inputs are evaluated and stored for the preceding geometry socket in
the order that the sockets are shown. Simulation state items can be added
by linking one of the empty sockets to something else. In the sidebar, there
is a new panel that allows adding, removing and reordering these sockets.
The simulation nodes behave as follows:
* On the first frame, the inputs of the `Simulation Input` node are evaluated
to initialize the simulation state. In later frames these sockets are not
evaluated anymore. The `Delta Time` at the first frame is zero, but the
simulation zone is still evaluated.
* On every next frame, the `Simulation Input` node outputs the simulation
state of the previous frame. Nodes in the simulation zone can edit that
data in arbitrary ways, also taking into account the `Delta Time`. The new
simulation state has to be passed to the `Simulation Output` node where it
is cached and forwarded.
* On a frame that is already cached or baked, the nodes in the simulation
zone are not evaluated, because the `Simulation Output` node can return
the previously cached data directly.
It is not allowed to connect sockets from inside the simulation zone to the
outside without going through the `Simulation Output` node. This is a necessary
restriction to make caching and sub-frame interpolation work. Links can go into
the simulation zone without problems though.
Anonymous attributes are not propagated by the simulation nodes unless they
are explicitly stored in the simulation state. This is unfortunate, but
currently there is no practical and reliable alternative. The core problem
is detecting which anonymous attributes will be required for the simulation
and afterwards. While we can detect this for the current evaluation, we can't
look into the future in time to see what data will be necessary. We intend to
make it easier to explicitly pass data through a simulation in the future,
even if the simulation is in a nested node group.
There is a new `Simulation Nodes` panel in the physics tab in the properties
editor. It allows baking all simulation zones on the selected objects. The
baking options are intentially kept at a minimum for this MVP. More features
for simulation baking as well as baking in general can be expected to be added
separately.
All baked data is stored on disk in a folder next to the .blend file. #106937
describes how baking is implemented in more detail. Volumes can not be baked
yet and materials are lost during baking for now. Packing the baked data into
the .blend file is not yet supported.
The timeline indicates which frames are currently cached, baked or cached but
invalidated by user-changes.
Simulation input and output nodes are internally linked together by their
`bNode.identifier` which stays the same even if the node name changes. They
are generally added and removed together. However, there are still cases where
"dangling" simulation nodes can be created currently. Those generally don't
cause harm, but would be nice to avoid this in more cases in the future.

Pull Request: blender/blender#104924
This adds the ability for users to assign sub-types to `Float` type custom properties (e.g., distance, angle, time, power etc.)
Pull Request: blender/blender#106700
When pressing F3 to bring up the Search Menu, an error appeared
because the MoveModifierToNodes operator's poll method did not
consider the context where no object was selected.
Pull Request: blender/blender#107310
This property is not editable after 7966cd16d6,
though doing so didn't seem to give an error. It doesn't have
to be set anymore, since the data is redundant with the
"loop_start" anyway.
Give errors in a few cases:
- The mesh has no UV map
- The faces have no area
- The applied modifier has no curve data (it may have been modified)
Use errors instead of cancelling the operator completely so the
operator can still do something useful when many meshes are
selected and only some fail.

Makes it possible to select multiple custom script directories in Preferences >
File Paths, replacing the single Scripts path option. Each of these directories
supports the regular script directory layout with a startup file (or files?),
add-ons, modules and presets.
When installing an add-on, the script directory can be chosen.
NOTE: Deprecates the `bpy.types.PreferencesFilePaths.script_directory`
property, and replaces `bpy.utils.script_path_pref` with
`bpy.utils.script_paths_pref`.

Currently assigning values to IDProperties clears their UI data.
That is fixed by #106161, but that is too risky for 3.5. Instead,
work around the issue by triggering `MOD_nodes_update_interface`
function which recreates the UI data of the modifier properties.
Pull Request: blender/blender#106190
Move the deform curves with surface node group to last so it affects the
final generated curves consistently (though this will have a negative
performance impact), and make the generate and interpolate modifiers use
the surface mesh's rest positions.
When trying to use the Fill Range by Selection operator, in the
Distance from Camera Freestyle modifier, the operator fails if no
camera is active in the scene.
Before getting the data from the camera, check that it is defined, and
return otherwise.

This has the effect that the message is cut off at the end of the
first line. I copied the solution from other similar docstrings
elsewhere in the code.
As far as my regex-fu can tell, there are no other occurrences of this
in the codebase.
Issue reported by Joan Pujolar in #43295.
Pull Request #105474
The toggle (for anything but float and int types) was swallowed in
bf948b2cef. Also seems ef68a37e5d discarded
`property_overridable_library_set` for bools.
Now treat the overridable toggle as a general property for all property
types.
Pull Request #105370
This commit implements described in the #104573.
The goal is to fix the confusion of the submodule hashes change, which are not
ideal for any of the supported git-module configuration (they are either always
visible causing confusion, or silently staged and committed, also causing
confusion).
This commit replaces submodules with a checkout of addons and addons_contrib,
covered by the .gitignore, and locale and developer tools are moved to the
main repository.
This also changes the paths:
- /release/scripts are moved to the /scripts
- /source/tools are moved to the /tools
- /release/datafiles/locale is moved to /locale
This is done to avoid conflicts when using bisect, and also allow buildbot to
automatically "recover" wgen building older or newer branches/patches.
Running `make update` will initialize the local checkout to the changed
repository configuration.
Another aspect of the change is that the make update will support Github style
of remote organization (origin remote pointing to thy fork, upstream remote
pointing to the upstream blender/blender.git).
