- Silence harmless error print about relation.
Object with particle system which doesn't use physics will
not have point cache component.
- Tag relations for update when particle system physics type
change.
This ensures correct state of point cache component.
This is all part of T59258.
This commit makes it so curve path parent solving accepts an explicit
arguments for both time and curve speed flag, making it so we don't
have to mock around with scene's frame.
One unfortunate issue still is that if the instancing object is used
for something else, we might be running into a threading conflict.
Possible solution would be to create a temp copy of an object, but
then it will be an issue of preventing drivers from modifying other
datablocks.
At least the original issue is fixed now, and things behave same as
in older Blender version. Additionally, the global variable which
was defining curve speed flag behavior is gone now!
Textures are now hooked up to the RESET operation of particle
settings, which ensures particles being re-distributed when
texture is changed.
This is limited to a direct user modifications, which matches
old behavior in 2.79.
There is no guarantee that object in rigidbody collection already have a
valid rgigidbody data when rebuilding deg relations, that is often
generated on-the-fly by actual rigid body simulation.
Note that this can be an issue when generating deg relations I guess...
But at least it won't crash anymore.
This fix aims to fix crash/assert failure related on wrong
evaluation order which happens when there is a cyclic
dependency involved.
The rationality of this change is that we can allow use
of uninitialized scalar value, but memory is better be
allocated.
This might not be ideal still, but worth a try.
There were at least three copies of those:
- OB_RECALC* family of flags, which are rudiment of an old
dependency graph system.
- PSYS_RECALC* which were used by old dependency graph system
as a separate set since the graph itself did not handle
particle systems.
- DEG_TAG_* which was used to tag IDs.
Now there is a single set, which defines what can be tagged
and queried for an update. It also has some aggregate flags
to make queries simpler.
Lets once and for all solve the madness of those flags, stick
to a single set, which will not overlap with anything or require
any extra conversion.
Technically, shouldn't be measurable user difference, but some
of the agregate flags for few dependency graph components did
change.
Fixes T58632: Particle don't update rotation settings
The issue was caused by transflag set in geometry evaluation
never copied back top original object.
Now we have a dedicated operation which does all sort copy
back to original object, so we don't have to worry about
atomic assignments or what gets set where.
Still need to move boundbox to the same function, but it
needs some careful doublechecking first.
Move all mask-related fields from Object and OperationDepsNode
to Object_Runtime and IDDepsNode. Auto-apply DEG_TAG_GEOMETRY
if the mask changes after DEG rebuild. Update DEG API and all
code that uses it.
This fixes "source mesh data is not ready" errors from Data
Transfer modifier when parameters are changed in the UI after
the recent mesh_get_eval_final fix.

See T57857 for discussion. This reverts:

"Remove eye column from the outliner"
fd16b35997.
Fix/workaround issues in pose and edit mode"
6d2e2e30d5.
"Per view-layer collection visibility"
4de6a210c6.
We still control this in the viewport collections visibility menu. But
now we are actually changing the visibility of the collections, not of
the objects.
If a collection is indirectly invisible (because one of its parents are
invisible) we gray it out.
Also if you click directly in the collection names, it "isolates" the
collection by hiding all collections, and showing the direct parents and
all the children of the selected collection.
Development Note:
Right now I'm excluding the hidden collections from the depsgraph.
Thus the need for tagging relations to update.
If this proves to be too slow, we can change.
Computing the shape of a B-Bone is a quite expensive operation, and
there are multiple constraints that can access this information in
a variety of useful ways. This means computing the shape once per
bone and saving it is good for performance.
Since the shape may depend on the position of up to two other bones,
often in a "cyclic" manner, this computation has to be a separate
node with its own dependencies.

This way we guarantee that action tagged for CoW will ensure
order of updates with objects which are using it.

Previously each of the objects which has armature modifier will
request deformation matricies from bbones. Thing is, all those
deformations are the same and do not depend on object which is
being modified. What's even worse is that this calculation is
not cheap.
This change makes it so bbones deformation is calculated once
and stored in the armature object. After this armature modifiers
simply use it.
With a rigs we've got here dependency graph evaluation time
goes down from 0.02 sec to 0.012 sec.
Possible further optimization is to make bbone deformation
calculated at the time when bone is calculated. This will avoid
an extra threaded loop over all bones.
The issue was caused by dependency cycle solver killing relation
which was guaranteed various things: i.e. copy-on-write component
orders and pose evaluation order (which must first run pose init
function).
Now it is possible to prevent such relations from being ignored.
This is not a complete fix, but is enough to make this specific
rig to work. Ideally, we also need to run copy-on-write operation
prior to anything else.
Do early output when trying to add target relation with wrong rna_path.
We can't do anything reliably in that case anyway, so hopefully it is
a no-functional-change for artists, just avoids noisy error prints in
the terminal.
This finished old standing TODO which was attempting to
ignore objects of all invisible collections.
The difference here is that we remove invisible bases from
view layers. This guarantees that the evaluated state is
consistent and does not reference original objects.
Rig generators (e.g. rigify) use dummy drivers to attach extra
ID references to rigs for Append/Link. These references use
Single Property variables with empty path, which is intentionally
invalid and shouldn't produce low-level error logs from depsgraph.
The removed code would always print an error because RNAPathKey
requires a valid path to produce a non-NULL reference.
Among all the lines moved around, the general idea is quite simple.
Actually, there are two ideas implemented there.
First one, is when object itself is tagged for update, we tag its
point cache component for evaluation, which makes it so point cache
is properly reset. We do it implicitly because otherwise we'll need
to go everywhere and add explicit tag in almost all the properties.
Second thing is, we link all collider and force fields to a point
cache component using special type of link. This type of link only
allows flush if change is caused by a user update. This way reset
does not happen when change is caused due to animation, but will
properly happen when user causes indirect change to the objects
which are part of physics simulation.
