[#25011] Opacity IPO not refreshing with still images
(should be better named: animation of any prefiltering parameters using
still images didn't work out as expected)
And this issue by private mail by Ton:
"I tried to debug a memory-free error; very simple case:
- add image strip
- click on strip at 2 places
- quit blender"
Surprising this wasnt noticed in a much more obvious case:
- Key Location, Move, Rotate, Undo-Rotate >> Resets to keyed location as well.
This was happening because DAG_on_load_update() was called on read_undosave(), flagging 'ob->adt->recalc |= ADT_RECALC_ANIM;'
Fix by adding an option to DAG_on_load_update(), not to recalculate time flags.
Multi-layer images: clicking on the "Source" popup freed all memory
for multilayers, even when choosing the same "File" entry again.
Now it should work :)
* Depsgraph wasn't updated properly for smoke flow collision object dependencies.
* Smoke also wasn't properly using the actual emission frame of the flow particles.
* There was a lot of bloated logic in some parts of particle code so this fix turned into a small scale cleanup operation.
** As a result particle updating and cache usage should be a bit more stable too.
Root cause is that some drawing modes don't work with PBVH
drawing. Worked around by adding a call to update mesh normals from
the PBVH so that sculpted changes appear correctly in those
"unsupported" modes. (They'll still draw much more slowly than solid,
but should at least appear correct now.)
Sculpt data shouldn't be lost when making topology changes without
quads<->tris face converison.
General idea:
- Go through all grid points of each corner and convert per-corner
coordiante to per-face cooredinate
- Apply weights and convert new point to per-corner coordinate
- Use bilinear interpolation to get needed displacement vector
Some additional work was necessery:
- Two neighbour corners could have different displacements along common
boundary. multires_mdisp_smooth_bounds() makes displacement "symmetrical"
- Point could change it's corner, so displacement vector should be flipped
in some way. In some cases it's not only flipping, because corner could
be mapped with some rotation. It's not solved for triangular faces yet,
so only z-axis displacement would be interpolated for tris.
More limitations:
- Interpolation will give incorrect result after quad<->triangle
face conversion.
- When face normal was fillped displacement would change it's direction too.
Compositor/Image viewer
In 2.4x viewer nodes had animation playback. Not restored yet.
However, when loading such older files the viewer never showed
any result.
* New option to "Regrow hair" for each frame.
* This was perhaps more a feature request, but there was a similar useful feature called "animated hair" in particles at some point.
* The previous behavior for hair growing was inconsistent to say the least, so this is a nice option to have.
This allows manual (point by point) animation of their control verts,
although many other settings cannot really be animated with any
visible effects yet. Interestingly, lattices also had IPO block
pointers, though they were never really used (AFAIK).
Todo:
- Animation Editor support has yet to be added. I've got a few other
things to add to, so will group those changes together.
* Calling update_children(..) is very light if there's nothing to update, so it doesn't matter if it's called every time the particle system is updated.
[#25159] Vertex locations dont read correctly and are not labeled correctly in the properties bar.
- non rna buttons can now have units set.
- calls with invalid units system now raises an assert().
- include .mxf in filter.
This is need to properly handle 3d text (dalai work on GE), before
the BLF_aspect only take one argument, and the result was a call to:
glScalef(aspect, aspect, 1.0)
Now the three value are store in the font (x, y and z) and also
need to be enable using BLF_enable(BLF_ASPECT).
By default all the code that don't have BLF_ASPECT enable work with
a scale of 1.0 (so nothing change to the current UI).
I also remove all the call of BLF_aspect(fontid, 1.0) found in
the editors, because is disable by default, so no need any more.
Campbell the only thing to check is the python api, right now
I modify the api to from:
BLF_aspect(fontid, aspect)
to:
BLF_aspect(fontid, aspect, aspect, 1.0)
This is to avoid break the api, but now you need add the BLF_ASPECT
option to the function py_blf_enable and in some point change
py_blf_aspect to take 3 arguments.
Two isses:
- Material assigning to MetaBalls used wrong pointer
(copy paste error, casting badly).
- Checking for node-material used wrong RNA pointer
(confusing void stuff going on here!)
The error leads to corruption in data and/or random
crashes. Better update svn now!
An error seems to have been introduced to the node-tree building at some point, which means that the ID-type for data-attached node trees was incorrect (i.e. scene->nodetree->id.name = NTREE_COMPOSIT instead of ID_NT).
This in turn meant that the ID AnimData availability poll would fail, as the ID-type could not be determined.
This would have made bug #25003 very simple to find.
- Objects had their quats normalized when calculating their matrix, this is inconstant with pose bones and isn't useful for animation.
Also it wasn't normalizing the delta rotation so these would give bad rotations.
- Converting between rotation modes BKE_rotMode_change_values() assumed normal length quat. changing quat to euler rotation for eg could change the bone.
- Clear rotation and transform were not normalizing the quat when 4d loc was disabled on quat rotation, corrected and also made it so the quat scale is restored after conversion so animations curves dont jump.
There is 1 case in mat3_to_quat_is_ok() where quat_to_mat3 on an unnormalized quat is needed, for this I had to add an ugly static function quat_to_mat3_no_assert(), but overall its worthwhile IMHO to be able to find incorrect use of rotation conversion.
- skip fixing file paths on undo.
- simplify bpath alloc and free functions, also pass Main structure so as not to rely on G.main, (needed for file load).
- loop over sequencer plugin and texture voxel paths.
- fix leak in python bpy.utils.blend_path() and use PyUnicode_DecodeFSDefault() to ensure correct paths with different encodings.
- operators to make paths absolute & relative now redraw the view.
only tags the ID and does the actual flush/update delayed, before the next
redraw. For objects the update was already delayed, just flushing wasn't
yet.
This should help performance in python and animation editors, by making
calls to RNA property update quicker. Still need to add calls in a few
places where this was previously avoided due to bad performance.
* Old boids didn't have all of the necessary data for the new system.
* Changed the particles code so that a check for all necessary data is always done before starting actual dynamics calculations.
* Rendering a scene strip updated all animation data to it's frame, so fcurves were left with the wrong value.
* Now the animation data is recalculated to original frame after rendering each scene strip.
