The idea is following: we do need to have multiple dependency graphs to denote
different scene layers (depsgraph should only contain objects from a specific
scene layer), and we also want to support same scene layer to be evaluated to
a different state in different windows. In order to achieve that we do need to
have a list or hash (for faster lookup presumably) somewhere. To keep things
easier for now, it will be a scene which owns that hash. This seems to make
sense anyway, since dependency graph only points to data which is owned by
scene.
This commit only introduces some basic API and hash itself stored in DNA, there
is no changes in behavior. See this as a first step towards getting rid of
scene-global dependency graph.
This was never correctly implemented. It now works as expected (ala 2.79 behaviour).
The proxy object is added to all the collections of the original empty.
Before not only this wasn't the case, but it would crash Blender.
Loading blender with an unknown name would interpret it as a blend file.
This meant passing `--arg` arguments would end up creating new
blend files which could be confusing if you made a typo on a command
line argument.
Now check the string has a blend file extension,
exiting if it doesn't.
This only applies when LIB_ID_CREATE_NO_ALLOCATE flag is used and guarantees
that non-memset-zero memory can be used (or, that same memory chunk might be
used over and over again without need to clean it from the calleer).
OUr beloved root nodetrees... Had to check again the code to undersand
why we copy them with bmain even though they are not in bmain, so this
is worth a comment. ;)
Changes from D2876 by @meta-androcto /w own edits
Move 3x undo items into Undo menu,
these are such common operations they're typically accessed by keys.
Also add to menus which didn't have undo
(seemed random which modes had undo, undo history in their menus).
Changes from D2876 by @meta-androcto /w own edits
- Move view axis & camera selection into "Viewpoint" menu.
- Move render border and clipping into border menu.
- Move Camera operators into own menu.
- View Selected was located in two menus,
Only expose the "use_all_regions" version when quad-view is used.
This solves issue with user counter on materials, objects and such,
additionally avoids having too much overhead of temporary lock and
datablock allocation.
Still need to do similar thing for scene copy, and look into nested
ID datablocks somehow.
Before it was a compile time option which was not very easy to use or test. Now
the project is getting more mature, so very soon we will be able to call for a
public tests of limited features.
The copy-on-write (which includes animation, modifiers) is enabled using
--enable-copy-on-write command line argument.
This is fully unpredictable for artists when one damaged object makes the whole
scene to render incorrectly. This involves two main changes:
- It is not enough to check triangle bounds to be valid when building BVH.
This is because triangle might have some finite vertices and some non-finite.
- We shouldn't add non-finite triangle area to the overall area for MIS.
