2019-09-25Cleanup: Modernize Smooth modifier code.Bastien Montagne
Simplify it a bit, hopefully make it clearer, better var names, use proper types for arrays of vectors, etc. No behavioral change expected (except for corner-case of vertices being used by more than 255 edges, which were sort of 'clamped' to those 255 first edges for the smoothed position computation previously, now we use proper integer, which fixes that bug).
2019-09-25Fix T69542: Corrective Smooth modifier breaks when drivers are involvedSebastian Parborg
Previously the cache for the modifier would not be invalidated if modifier settings were changed with drivers or keyframes. Now we compare the current setting with the ones used to generate the cache and invalidate the cache if they differ. Reviewed By: Sybren Differential Revision: http://developer.blender.org/D5694
2019-09-23Modifiers: every modifier now copies mesh settings, fixing texture space issuesBrecht Van Lommel
Modifier stack evaluation would copy mesh settings other than mesh topology automatically, outside of the individual modifier evaluation. This leads to hard to understand code, and makes it unclear which settings are available in following modifiers, and which only after the entire stack is evaluated. Now every modifier is responsible to ensure the mesh it outputs preserves materials, texture space and other settings, or alters them as needed. Fixes T64739: incorrect texture space for various modifiers Differential Revision: https://developer.blender.org/D5808
2019-09-22Cleanup: MOD_explode: Sanitize code some more.Bastien Montagne
This happens to be a non-behavioral change, but previous code here was *very* confusing, and only ended up generating expected results by mere chance (since `facepa[i]` == `totpart` in case the face has no (valid) particle, i.e. `pa == NULL`)...
2019-09-22Cleanup: MOD_Explode: sanitize face-without-particle case.Bastien Montagne
Systematically reset particle pointer to NULL and use it to detect invalid particle case, instead of checking value of the face's particle index everywhere in a confusing and prone-to-bug way (see T70150 and previous commit). No behavioral change expected here.
2019-09-22Fix T70150: Explode modifier crashes with empty vertex group.Bastien Montagne
There’s be a lot to say about that explode modifier code, for now just follow other places in code... But the handling of 'invalid'/'unkown' particle case is... quiet confusing to say the least.

Currently unused but the intention is to use this to hook up these modifiers to a generic deformed PBVH to make it easier to sculpt or paint on a subdivided mesh.

2019-08-23Fix potential issues when loading files with missing librariesSebastian Parborg
This is a continuation of rB39f005eae8eed8b939579aff8c9a05a4f50e5e38 Now all the fields where we check for object type in RNA (like rna_Curve_object_poll) will have a safe guard for when this isn't the case. For example when loading files that has missing object libraries and all missing objects are replaced with empties (placeholders).

2019-08-16Fix T56408: Hair children recalc on every frame on Alembic meshSybren A. Stüvel
This fixes the glitching hairs described in T56408, T63534, and possibly also T63534. The fix consists of returning the original mesh (i.e. as visible in edit mode) when constructing the ORCO mesh. This allows a static set of coordinates to be used when computing the child hair positions. The original mesh is only returned when it has the same topology (at least same number of vertices, loops, and polys. It's up the author of the Alembic file to ensure stable geometry when it's desired to be compatible with Blender's hair system.

In the case where the library is missing, the armature object is replaced with an empty. This would crash the armature modifier. Now we check if the armature object really is an armature or not.

2019-07-30BLI_task: Cleanup: rename some structs to make them more generic.Bastien Montagne
TLS and Settings can be used by other types of parallel 'for loops', so removing 'Range' from their names. No functional changes expected here.
2019-07-26Modifiers: Update LaplacianDeform error message about vgroups.Bastien Montagne
Vgroup might be also 'invalid' because it is empty (and no other vgroup with vertices currently exists on that mesh). Related to T67385.

2019-07-09Fix T64149: Texture paint can act as a canvas and brush at the same timeSebastian Parborg
I don't know if it was the intended behavior or not, but having brush and canvas data at the same time with dymanic paint, would lead to the object trying to act as a brush and a canvas at the same time. We can't currently handle this with the new depsgraph, and it could legitimately lead to bad feedback loops. So now, to be more consistent with the GUI, I've made it only use the current set type (brush or canvas) as the final type of the object. That is, you can only have a object be a brush or a canvas, not both at the same time.

2019-06-17Fix T59915: Skin modifier produces inverted normals on end-cap faces when ↵Sebastian Parborg
vertically aligned edge is assigned root Sometimes when the end caps pointed strait up (z axis) their faces would become inverted. It seems like the code tried to rely on a certain vertex order to always happen. However this edge case did manage to produce an order that would produce inverted cap faces. So now I introduce a normal check instead so we can be certain that the face will have the normal direction we want.
