This is in order to have more flexible ligthing presets in the future.
The diffuse lighting from hdris was nice but lacked the corresponding
specular information. This is an attempt to make it possible to customize
the lighting and have a cheap/easy/nice-looking pseudo-PBR workflow.
* Add cheap PBR to Workbench with fresnel and better roughness support.
This improves the look of the metallic surfaces and is easier to control.
* Add ambient light to studio lights settings: just a constant color added
to the shading.
* Add Smooth option to studio lights settings: This option fakes the
effect of making the light bigger making the lighting smoother for this
light. Smoother lights gets reflected like a background hdri.
* Change default light settings to include the smooth params.
* Remove specular highlights from flat shading. (could be added back but
how do we make it good looking?)
* If specular lighting is disabled, use base color without using metallic.
* Include a lot of code simplification/cleanup/confusion fix.
The idea is to make main thread and job threads to be scheduled
on CPU dies which has direct access to memory (those are NUMA
nodes 0 and 2).
We also do this for new EPYC CPUs since their NUMA nodes 1 and 3
do have access but only to a higher range DDR slots. By preferring
nodes 0 and 2 on EPYC we make it so users with partially filled
DDR slots has fast memory access.
One thing which is not really solved yet is localization of
memory allocation: we do not guarantee that memory is allocated
on the closest to the NUMA node DDR slot and hope that memory
manager of OS is acting in favor of us.
See T57857 for discussion. This reverts:
"Outliner: Do not gray out empty collections"
4521d3e707.
"Remove eye column from the outliner"
fd16b35997.
Fix/workaround issues in pose and edit mode"
6d2e2e30d5.
"Per view-layer collection visibility"
4de6a210c6.
A few reasons motivating this change:
* It works well for all devices: mouse, trackpad, and tablet pens.
* For beginners or users coming from other software, it's easier to get
started and avoids an initial stumbling block.
* Many users in 2.7 (about half?) were already using left click select, so
combined with the above advantages it makes for a practical default.
Note that we continue to support right click select, as many experienced
Blender users (and developers) see efficiency advantages in this approach.
The option to switch is in the first time setup splash screen, and in the
user preferences.
Curve/surface/text final data may be an evaluated mesh instead of a
displist, when some modifiers (constructive ones in particular) are
applied to it.
Note that this is just getting feet wet, whole draw code suffers from
the same issue! :P
We still control this in the viewport collections visibility menu. But
now we are actually changing the visibility of the collections, not of
the objects.
If a collection is indirectly invisible (because one of its parents are
invisible) we gray it out.
Also if you click directly in the collection names, it "isolates" the
collection by hiding all collections, and showing the direct parents and
all the children of the selected collection.
Development Note:
Right now I'm excluding the hidden collections from the depsgraph.
Thus the need for tagging relations to update.
If this proves to be too slow, we can change.
To control per-viewlayer, per-object visiblity users should either use
the menu or the H shortcuts (H, Alt+H, Shift+H).
Following next will be to have proper per-viewlayer collection
visibility. This will replace the functionality currently at the
viewport collections visibility menu.
Previously we tried this but reverted (see 64d40c82c3)
because there wasn't a predictable set of keys to use global-space.
Now the keys are swapped:
- 'GX' always transforms in the user defined orientation.
- 'GXX' always transforms in global space.
As before 'GXXX' cycles back to disabling constraints.
This does have a down side that GXX won't be used for local-space
when the user has global space set.
Also, when global is the user-orientation, pressing GX and GXX
does the same thing.
Note: examples here use GX but could be any transform-mode/axis.
When a modifier depends on some other object's position, then it also
depends in its own position, this has to be also told to depsgraph.
Fixes several modifiers where moving target would update the modifier,
while moving modified object itself would not.
Also fixes a few issues (like meshdeform's EM variant not using editmesh
data), and adds a few optimizations (like only generating that source
mesh when we do have a vgroup defined in parameters, for modifiers only
using it to access vgroup)...
