This should have been done earlier. But now that we may see more activity in master due to bcon3 merges, it is even more important to stress out the separation between master and 2.8.
Also I needed the version bump for idproperties doversion (they needed
to happen in _after_linking, and we don't have access to
DNA_struct_elem_find there).
Last but not least, every time I posted a video or image from 2.80, I
got someone confused about the version showing in the infobar.
In this case the Pyobject gets lost from pybm, and bm.free() does not invalidate the PyElem.
This will cause the destructor of python to read invalid memory and crash.
The solution is to make a copy of the pyobjects pointers before overwriting.
First this replace a custom data struct with IDProperty, and use
IDProperty group merge and copying functions. Which means that a collection
property setting is only created if necessary.
This implements the "Layer Collection settings" override system, as
suggested in the "Override Manifesto" document.
The core is working, with Scene, LayerCollection and Object using a
single IDProperty to store all the render settings data. Next step is to
migrate this to depsgraph.
Note: Clay engine "ssao_samples" was hardcoded to 32 for now. It will come
back as part of "Workspace Settings" later.
Many thanks for Bastien Montagne for the help with the UI template
nightmare ;)
Differential Revision: https://developer.blender.org/D2563
This area is a subject of reconsideration, so for now used simplest
way possible -- ensure depsgraph's nodes have proper layer flags
when going in and out of local mode.
GPU_framebuffer no longer handles transform matrices, which this code was relying on. Made screen_preview_draw responsible for its own ModelView matrix.
This restores the feature for legacy viewport only. Modern viewport, Clay, Eevee, etc. will need further work.
Eventually we should rename this something other than "OpenGL".
I was hoping this would fix the issue of the object not moving after you copy it (right now you need to manually grab the object afterwards). But unfortunatelly it does not
rB870440dee910c9 just did NULL-check for Main pointer, actual issue is
that bContext pointer was NULL. This can be fixed by ensuring
PROP_ENUM_NO_CONTEXT flag is not set by calling
WM_operator_properties_sanitize when creating RNA buttons. Now, layout
previews are visible in keymap editor too.
That one was:
* Resetting non-ID pointers (lib_link_xxx funcs should only affect ID
pointers, everything else shall be done in direct_link_xxx func).
* Even worse, always calling lib_link_animdata, even when
LIB_TAG_NEED_LINK tag was unset...
