User side:
* Preview for DynamicPaint should keep the same behavior (for now). Weight preview should be somawhat quicker, though.
* Preview for WeightVG modifiers is only active in WeightPaint mode, and if the affected vgroup is the active one.
* Last active preview modifier in stack wins!
Note: that modifier preview topic is yet to be further refined, quite raw/incomplete for now.
Dev side:
* In draw code, renamed DRAW_DYNAMIC_PAINT_PREVIEW flag to DRAW_MODIFIERS_PREVIEW
* Removed use of MOD_DPAINT_PREVIEW_READY in DynamicPaint code (seems unecessary, and if it was, should be of more general scope).
* Added eModifierTypeFlag_UsesPreview to ModifierTypeFlag, for modifiers that can generate some preview data.
* Added three new modifier funcs, to handle preview modifiers in draw code / mod stack.
* For weights preview: added the generic DM_update_weight_mcol func, which can update WEIGHT_MCOL layer with either a given array of weights (currently used by DynamicPaint only), or from current active vgroup(s).
So now, draw code is fully generic (i.e. no more modifier-type checking in it). Mod stack code is generic to some extent, but will need more work.
Also, allow applying to obdata those modifiers, even with shapekeys, but do not allow applying them *as* shapekey (as shapekeys do not have CD layers).
Fix [#29636] Vertex Weight Mix modifier "apply" button don't work.
Note: applying whit shape keys currently always uses base shape, not current one (for apply to obdata as well as apply to shapekey), but this is another topic...
Used a crazyspace approach (like in edit mode), but only modifiers with
deformMatricies are allowed atm (currently shapekeys and armature modifiers only).
All the rest modifiers had an warning message that they aren't applied because
of sculpt mode. Deformation of multires is also unsupported.
With all this restictions users will always see the actual "layer" (or maybe
mesh state would be more correct word) they are sculpting on.
Internal changes:
- All modifiers could have deformMatricies callback (the same as deformMatriciesEM but
for non-edit mode usage)
- Added function to build crazyspace for sculpting (sculpt_get_deform_matrices), but it
could be generalized for usage in other painting modes (particle edit mode, i.e)
Todo:
- Implement crazyspace correction to support all kinds of deformation modifiers
- Maybe deformation of multires isn't so difficult?
- And maybe we could avoid extra bad-level-stub for ED_sculpt_modifiers_changed
without code duplicating?
When there are 2+ consecutive deform modifiers, the second modifier was getting incorrect normals, this only showed up for the displace modifier since its the only deform modifier that uses vertex normals.
It would have been easy to fix this by always calculating normals on deform modifiers, but slow.
To fix this I added a function to check if a deform modifier needs normals, so the normal calculation function only runs if there are 2 modifiers in a row and the second uses normals.
Fixed bug #23657, "Modifiers dosen't work when you select diffrent mesh for object"
Multires modifier now adds empty mdisps if they're missing, rather than displaying a warning
Switching an object's mesh will now check for a multires modifier; if found the modifier's total number of levels are reset to match the mesh's mdisps
Switching the mesh also forces a multires update so that sculpted changes aren't lost
is still set very low so in many cases it could be even smaller, but being
a bit conservative here to try to avoid breaking rigs.
This is not forward-compatible, i.e. loading new files in older blender
versions will loose the binding.
Previously all modifier operators relied on the buttons layout data context pointer to
decide which modifier to work on. This meant that these operators would only work
from from the properties panel, and not from scripting/macros or for operator redo.
This commit makes all modifier operators take the modifier name as an operator
property, so the operators can be re-done or executed outside of the modifier panel.
When invoking the operators from the modifier panel, they automatically fill in the
operator property from context.
This isn't a perfect API design, but it does bring these operators in line with the design
of being able to access all UI functionality via other means like scripts.
levels, child particles, and shadow/SSS/AO quality.. Now also works on what
is displayed in the 3d view instead of only rendering, see panel in the scene
properties.
Most file changes were to make scene available in the isDisabled modifier
callback function.
Most likely will not compile for others, I'd appreciate any build errors
and missing files reports (I can never seem to get everything committed
and all the build systems working without help).
Porting over the sculpt/multires tools was a breeze,
thanks goes to brecht for a design that didn't exclude
ngons and was easy to port.
Note that I've not tested externally-backed multires
file support yet. Also, I still need to write version
patch code for some cases.
Some notes:
* Like trunk, topological changes don't update multires right,
so e.g. subdivide will duplicate multires data on the new faces,
instead of subdividing it.
* If you set the debug value (ctrl-alt-d) to 1 it'll turn on
my experiments in speeding up sculpting on higher-res multires
meshes (but note it makes partial redraw not completely accurate).
* There's a bug where you have to go through editmode to get out
of sculpt mode, not sure if I inherited or created this myself.
* Displacement coordinates are now stored differently, as a grid per
face corner. This means there is duplication of coordinates, especially
at low subdivision levels, but the simpler implementation justifies it
I think.
* ToDo: conversion of existing multires files (2.4x or 2.5x), loading them
may even crash now.
* Editmode preservation/interpolation code also has not been updated yet.
* Multires now works on the CCGDerivedMesh grids instead of CDDerivedMesh,
which should be more memory efficient.
* There are still bad memory peaks (if you're using 32bit) when subdividing
or propagating displacements. Though at least there should be no huge
memory blocks allocated, which windows is now to have trouble with.
* Still found some weird spike artifacts at lower multires levels, some also
happening before this commit. Perhaps computation of tangents needs to be
tweaked more.
* Multires modifier now has viewport, sculpt and render levels. Also the
levels have been made consistent with subsurf, previously the same level
of subdivision was one less for multires.
* Both multires and subsurf modifier now can have their subdivision level
set to 0 for no subdivision.
Rather than applying the modifier to the object data, it will create a new shape
with the deformed vertices in there. Only mesh at the moment, other object
types on the todo.
Blended shape keys can now be displayed & edited in edit mode. This
is much like showing an armature modifier in edit mode, and shape keys
now are a applied as a virtual modifier (for mesh & lattice only, curve
doesn't fit in the stack well due to tilt).
The main thing missing still is being able to switch between the active
shape key in edit mode, that's more complicated.. but the weights of
other shapes can be edited while in edit mode.
One thing to be careful about is that this does automatic crazyspace
correction, which means that if you edit a shape key with a low value,
the actual vertices will be moved to correct for that and actually move
a (potentially much) longer distance.
Also includes some UI tweaks, mainly placing some buttons horizontally
since the vertical list was getting too long.
* #19583: Keying Sets list issues
Deleting a Keying Set (or a Keying Set Path) set the active index to 0, but that would mean that the first item would be selected but not visible.
* #19590: Keyframing properties of a modifier with more than one of it's type the property will highlight in all
- Modifiers now always have a unique name, so renaming a modifier should check that the name is unique. Most of the files changed in this commit were just to make sure that modifiers got unique names when they were created
- Modifiers path getter was wrapped a bit wrong (missing the "s around the name)
* Constraints Bugs
- Constraints renaming now also makes sure the names stay unique
- Fixed (or attempted to fix) compiler warnings about some enum declaration for distance constraint
* Popup menus now remember the last clicked item again.
* Modifier and File Format menus are now organized in multiple
columns with categories.
* Hook, explode, uv project modifiers have all their buttons
again with the relevant operators implemented.
* Modifiers that can't be added by the user, or don't work on
curves for example, are not in the menu anymore.
* Fix search menu overlapping buttons when near the bottom of
the screen.
* Fix uv layers search menu not working in some modifiers.
* Cleanup popup menu code a bit, layout engine is used in more
cases now instead of ugly position calculation code.
All kinds of changes to get it ready for UI layouts. This means RNA
and operators should be working correct, but most buttons are still
not actually there yet.
* Added near empty soft body, fluid, field and collision panels,
tweaks to cloth panels.
* Fluid bake works, but without escape or showing any progress.
* Fluid/Softbody/Cloth/Collision can now be both added as modifiers
or in the physics panels.
* Missing: fields & soft body for particles.
* Missing: proper updating softbodies, guess this code still needs
updates after pointcache refactor?
