Seems it's just another issue with the compiler, worked around by explicitly
telling not to inline some function.
In theory we can unify this with CPU, but we're quite close to the release
so better be safe than sorry.
We need to register the exception handler slightly differently here, as
well as adding DbgHelp as a library, but according to docs it should be
supported in recent Windows editions (Win XP included even).
We can try it first and revert if there are issues.
The issue was caused by particles using billboard distribution, which
requires either object to be specified or camera in the scene to be
existing.
This commit prevents backing from crash, but bake result might not be
totally expected because of the thing mentioned above.
as complicated as before cloth solver changes.
Still doesn't solve the collapsing cloth cube issue mentioned in T43406,
probably the bending springs work somewhat differently now.
Face islands furthest faces could face towards the center point when connected to sharp edges.
Now check the furthest edge of the furthest face, to test for face winding.
This was disabled during the course of hair dynamics work. The cloth
collision solution is based on a secondary velocity-only solver step.
While this approach is usable in general, the collision response
calculation still does not work well for hair meshes. Better contact
point generation is needed here (Bullet) and preferably an improved
solver for unilateral constraints.
* Strips in muted tracks are also drawn with dotted borders now to make it clearer
that they are not contributing.
TODO:
* Perhaps dotted should be used for protected, and opacity for muted instead?
* Do not make Action Stash Tracks or their strips active/selected
* Lock the track to prevent accidental editing/adding of other strips
* Prevent strips from being added into locked tracks by the pushdown operator.
This is mainly to prevent pushdown actions from getting into the stash tracks.
This commit modifies the "New Action" operator to always stash the old action
before it creates a new one. As a result, the old active action will now have
a proper user of sorts after the new one is created, preventing previously
created actions from being lost.
Now that the New operator does this, it can be used for the Action Editor header AND
NLA Editor (Animation Data Panel -> Active Action) again. The "stash and create"
operator is somewhat redundant at this point as a result.
In constrast to the old "new" operator, this operator will stash the existing action
in the stack to prevent it from being lost. This situation isn't totally ideal yet,
since the NLA Editor still calls the old method.
I'm still not sure which version is better, but I suspect that with the labels,
this might help users figure this out more than if they were just unlabelled
icon buttons...
This operator (the snowflake icon, beside the pushdown button on the Action Editor
header) adds the currently active action to the NLA stack in a muted track, then
creates + loads a new action ready to be populated with new keyframes.
Since the NLA is being used to hang on to all the actions here, no actions are
getting lost.
Usage Notes (there will be some additional tweaks to make this nicer):
* To preview different actions that have been "stashed", simply click the "Solo"
toggle for the track containing the action in question. Playing back the NLA will
now show the stashed track
* To edit a previously stashed action - simply enter tweakmode on it in the NLA
while the "Solo" toggle is enabled.
Todo:
* Add some more operators here to polish up the Action <-> NLA bridge to make the
layered and stash workflows smoother. Examples include some tools to easily
switch between the different actions layers in the stack, as well as making it
easier to get out of tweakmode (and sync up the action lengths)
* Review and cleanup the behaviour of the "new" operator here to avoid the old
problems that users were running into
* After the next release - Implement the full Action Libraries functionality, with
ways to bridge the stashed strips over to a full-blown library.
