Fix alpha under equation according to porter-duff and user docs that
state that effect should invert he order of channels and reduce to alpha
over when factor is 1.0.
BTW, we don't really expose any factor here...lost feature from 2.49?
- clamp selection on entering editmode (Python may have changed).
- BKE_vfont_select_get no longer succeeds with an empty selection
this caused many operators to go ahead and operate on zero size array.
Core of the issue is that pointcache handling in depsgraph were (re-) tagging
for update some objects on hidden layers, when all their dependencies remained
untag.
Since we do not want to update objects on hidden layers, take this data into account
when flushing pointcache.
Investigations and org patch by self, reviews, advices and final patch by sergey, many thanks! :)
This was never implemented, actually... Was also the occasion to rework a bit
`curve_deform_verts()`, code there was sometimes needlessly complicated and slowish
(like getting weight from dm vertex per vertex, instead of whole array at once...).
Free draw objects instead of tagging object update and doing
recalculation of derived meshes. The reason is that if user deletes all
slots and tries to paint, the system will invalidate the cached in
projection painting derivedmesh. This will promptly crash. Invalidating
the draw objects only is also much cheaper.
Bring back shading in texture painting.
This works now but it uses 3 texture units instead of two. Most GPUs of
DirectX 8 (OpenGL 1.4 should cover that) functionality even should have
those, but some old GPUs might not work with that. In any case, I hope
we will be moving to OpenGL 2.1 requirement soon anyway where 4-8
texture units are usually the norm.
- Drawing grease pencil fail without scene-lock.
- Converting to curve failed without scene-lock.
- Outliner drag into viewport failed with local-view.
Include explicit control for texturing:
This commit introduces a painting mode option, available in
the slots panel. The default value "Material" will create slots from the
blender material, same as just merged from the paint branch.
The new option "Image", will use an explicit image field that artists can use
to select the image to paint on. This will should allow painting regardless
of the renderer used or for use in modifiers.
The issue was caused by the world localization setting the ID_WORLD
type update tag. Now using a function which doesn't pollute the library
and which doesn't set update flags.
