2016-12-01Fix (unreported) looptri array not being recalculated in ccgDM and emDMLuca Rood
In ccgDM and emDM, looptri array recalculation was being handled directly by `*DM_getLoopTriArray` (`getLoopTriArray` callback), while `*DM_recalcLoopTri` (`recalcLoopTri` callback) was doing nothing. This results in the array not being recalculated when other functions that depend on the array data called the recalc function. This moves all the recalculation code to `*DM_recalcLoopTri` and makes `*DM_getLoopTriArray` call that. This commit also makes a minor change to the `getNumLoopTri` function, so that it returns the correct number without having to recalculate the looptri array.

2016-10-13Fix T49534: 2.78 Wrong texture scaling in material viewportSergey Sharybin
Seems to be a bug in original implementation of a830280: code was always using tangent space instead of UV map because it had the same name. Now prefer UVMap over tangent because this is how Cycles works. At least it's closer to. Not sure it the save+reload issue is still relevant after this fix, that needs to be double-checked. Thanks @dfelinto for looking into the report and simplifying the case. Should be included into 2.78a.
2016-09-09Fix/Workaround T49297: Crash related to custom data draw (Blender with ASAN)Sergey Sharybin
Root of the issue is that active render index became wrong. This is the actual thing to be fixed, but as usual this is quite tricky to reproduce. Since such bad situation might have happened more and fix isn't really difficult or intruisive let's avoid crash for now. Can be revisited once we figure out root of the issue. Nice for 2.78 release.

2016-09-05Fix T49226: Incorrect Material viewport shading of Cycles Normal Map node in ↵Sergey Sharybin
Edit mode for an object with Array modifier Was incorrect indexing done in the array. Caused by 5abae51. Not sure why it needed to be changed here, but array here is supposed to be a loop data, so bringing back loop index as it originally was. The shading was wrong in edit mode with BI active as well (so it's not like it's needed for BI only). Patch in collaboration with Alexander Gavrilov (angavrilov), thanks! Should be double-checked and ported to 2.78.

2016-06-22EditMesh: Avoid creating deform-vert layer every redrawCampbell Barton
Getting a new edit-derived-bmesh was always creating a deform-vert array, even when it wasn't needed. Since this was called on redraw, in many cases it was doing it unnecessarily. Now pass in a custom-data mask and only fill in deform-verts when needed. Gives noticeable drawing speedup (~10-30% here).

2016-05-29BKE's DerivedMesh: get rid of last OMP usage.Bastien Montagne
Not replacing with some BLI_task_stuff here, tests show this is pointless (in absolute best case - i.e. single huge mesh in scene - parallelizing here switches from 0.8ms to 0.5ms for that piece of code - with something like 750ms per frame update...).

2016-04-26Support multiple tangents for BI render & viewportAlexander Romanov
Normal Map node support for GLSL mode and the internal render (multiple tangents support). The Normal Map node is a useful node which is present in the Cycles render. It makes it possible to use normal mapping without additional material node in a node tree. This patch implements Normal Map node for GLSL mode and the internal render. Previously only the active UV layer was used to calculate tangents.

Handling `me` data here is not good idea anyway, we override it completly with data from `tmp` (crash came from freeing already existing bb from me, while pointer still existed in tmp). (rediscovered it while working on T47676...). To be backported to 2.77.

2016-01-23OpenGL: call glLineWidth less oftenMike Erwin
Each LINES draw call is now responsible for its own line width. No need to set it back to its 1.0 default after every draw. This eliminates half our calls to glLineWidth , similar to last week’s work on glPointSize.
2016-01-21Weight Paint: Make multi-paint & mirror work as if bone selection was symmetricAlexander Gavrilov
The simplest way of handling mirroring in multi-paint is creating a uniform symmetric selection and relying on existing symmetric weights to direct changes to the appropriate vertex groups. This already works if mirror bones are selected manually, and can be made easier to use by doing it implicitly.
2016-01-20Weight Paint: 'Sample' now supports multi-paintAlexander Gavrilov
Since the coloring uses sum or average of the weights of all selected groups, the weight pick tool should also use that instead of reading the weight of the single active group that you can't see.
2016-01-20Weight Paint: reduce alert color brightnessAlexander Gavrilov
This condition can actually happen quite often if weight painting for a rig that uses separate control bones, so the color shouldn't be so bright that it's hard to look at for a significant amount of time.
2016-01-20Fix for tangent regression w/ looptri changesCampbell Barton
LoopTri changes in 2.76 calculated all tangents as triangles, this gave different results though in most cases it was hard to notice. Though no bugs were reported we should keep our tangents compatible with other users of mikktspace.

2016-01-20Support multi-paint & show zero-weights as blackAlexander Gavrilov
Specifically, when only one bone is selected and it's not really active. (With multiple bones on the other hand that behavior is forced on, since multi-paint can't modify purely zero weight verts and that's important.)
2016-01-04Fix T47038: Particles in Particle Edit Mode get added in completely wrong ↵Bastien Montagne
location. It also fixes another issue (crash) related to symmetric editing. Quite involved, we (try to!) fix complete broken logic of parts of particle code, which would use poly index as tessface one (or vice-versa). Issue most probably goes back to BMesh integration time... This patch mostly fixes particle editing mode: - Adding/removing particles when using generative modifiers (like subsurf) should now work. - Adding/removing particles with a non-tessellated mesh (i.e. one having ngons) should also mostly work. - X-axis-mirror-editing particles over ngons does not really work, not sure why currently. - All this in both 'modes' (with or without using modifier stack for particles). Tech side: - Store a deformed-only DM in particle modifier data. - Rename existing DM to make it clear it's a final one. - Use deformed-only DM's tessface2poly mapping to 'solve' poly/tessface mismatches. - Make (part of) mirror-editing code able to use a DM instead of raw mesh, so that we can mirror based on final DM when editing particles using modifier stack (mandatory, since there is no way currently to find orig tessface from an final DM tessface index). Note that this patch is not really nice and clean (current particles are beyond hope on this side anyway), it's more like some urgency bandage. Whole crap needs complete rewrite anyway, BMesh's polygons make it really hard to work with current system (and looptri would not help much here). Also, did not test everything possibly affected by those changes, so it needs some users' testing & validation too.
