- making local object data - Curve/Mesh/MBall lost references to linked materials.
- joining a linked mesh object into a local one lost the link.
As well as these reported bugs, checked all local functions for consistency/correctness and found other cases which would also fail.
- making local metaball didn't ensure unique ID name.
- make_local_armature() was missing check for object users - main body of code would never run.
- local particles didn't set the dupli-group or textures to extern.
checked all local functions for consistency/correctness.

Preview render for node shaders broke, caused by localizing
materials last week, to prevent thread crashes. Fixed now.
Also added a temp fix to draw color-management corrected
node previews default. Will follow scene setting tomorrow.
Also: SSS in nodes doesn't render yet. Was issue in 2.4 too...

flagged as PROP_THICK_WRAP.
Also use const char in many other parts of blenders code.
Currently this gives warnings for setting operator id, label and description since these are an exception and allocated beforehand.

- set_frame() --> frame_set()
- set_context_pointer() --> context_pointer_set()
material adding works for curves and metaballs, new function to remove materials.
materials.link() didnt well fit how this is used elsewhere
- order matters
- it can be linked more than once.
- remove(material), isnt that useful since you need to manage indicies.
... use list style functions instead. materials.append(mat) / materials.pop(index)
|
|
or get it from the context instead.

it myself, there will still be render slots just old implementation.
|
|
|
|
not enough room for the buttons so adding a menu, icon is ugly probably needs a new icon?.
|
|
- made texture_slot return the texture slot for the node texture

of materials to other selected objects, (like Ctrl+L, Materials in 2.4x)

Think global, act local!
The old favorite G.scene gone! Man... that took almost 2 days.
Also removed G.curscreen and G.edbo.
Not everything could get solved; here's some notes.
- modifiers now store current scene in ModifierData. This is not
meant for permanent, but it can probably stick there until we
cleaned the anim system and depsgraph to cope better with
timing issues.
- Game engine G.scene should become an argument for staring it.
Didn't solve this yet.
- Texture nodes should get scene cfra, but the current implementation
is too tightly wrapped to do it easily.

in EditButtons, panel "Links and Materials", there's now a browse button
to directly assign a material to selected faces. It does:
- check if material was already in one of the 'slots' of the object
- if so, then use this as index to assign
- if not, then add a new slot, and assign the new index

A full detailed description of this will be done later... is several days
of work. Here's a summary:
Render:
- Full cleanup of render code, removing *all* globals and bad level calls
all over blender. Render module is now not called abusive anymore
- API-fied calls to rendering
- Full recode of internal render pipeline. Is now rendering tiles by
default, prepared for much smarter 'bucket' render later.
- Each thread now can render a full part
- Renders were tested with 4 threads, goes fine, apart from some lookup
tables in softshadow and AO still
- Rendering is prepared to do multiple layers and passes
- No single 32 bits trick in render code anymore, all 100% floats now.
Writing images/movies
- moved writing images to blender kernel (bye bye 'schrijfplaatje'!)
- made a new Movie handle system, also in kernel. This will enable much
easier use of movies in Blender
PreviewRender:
- Using new render API, previewrender (in buttons) now uses regular render
code to generate images.
- new datafile 'preview.blend.c' has the preview scenes in it
- previews get rendered in exact displayed size (1 pixel = 1 pixel)
3D Preview render
- new; press Pkey in 3d window, for a panel that continuously renders
(pkey is for games, i know... but we dont do that in orange now!)
- this render works nearly identical to buttons-preview render, so it stops
rendering on any event (mouse, keyboard, etc)
- on moving/scaling the panel, the render code doesn't recreate all geometry
- same for shifting/panning view
- all other operations (now) regenerate the full render database still.
- this is WIP... but big fun, especially for simple scenes!
Compositor
- Using same node system as now in use for shaders, you can composit images
- works pretty straightforward... needs much more options/tools and integration
with rendering still
- is not threaded yet, nor is so smart to only recalculate changes... will be
done soon!
- the "Render Result" node will get all layers/passes as output sockets
- The "Output" node renders to a builtin image, which you can view in the Image
window. (yes, output nodes to render-result, and to files, is on the list!)
The Bad News
- "Unified Render" is removed. It might come back in some stage, but this
system should be built from scratch. I can't really understand this code...
I expect it is not much needed, especially with advanced layer/passes
control
- Panorama render, Field render, Motion blur, is not coded yet... (I had to
recode every single feature in render, so...!)
- Lens Flare is also not back... needs total revision, might become composit
effect though (using zbuffer for visibility)
- Part render is gone! (well, thats obvious, its default now).
- The render window is only restored with limited functionality... I am going
to check first the option to render to a Image window, so Blender can become
a true single-window application. :)
For example, the 'Spare render buffer' (jkey) doesnt work.
- Render with border, now default creates a smaller image
- No zbuffers are written yet... on the todo!
- Scons files and MSVC will need work to get compiling again
OK... thats what I can quickly recall. Now go compiling!

- Previews inside groups now get updated too
- Activating nodes inside of groups updates UI and preview render correctly
- Entering/leaving groups updates UI and previewrender
- Material Node: now draws socket name next to colorpicker for inputs

**** NEW: Group Nodes
Node trees usually become messy and confusing quickly, so we need
not only a way to collapse Nodes into single 'groups', but also a
way to re-use that data to create libraries of effects.
This has been done by making a new Library data type, the NodeTree.
Everything that has been grouped is stored here, and available for
re-use, appending or linking. These NodeTrees are fully generic,
i.e. can store shader trees, composit trees, and so on. The 'type'
value as stored in the NodeTree will keep track of internal type
definitions and execute/drawing callbacks. Needless to say, re-using
shader trees in a composit tree is a bit useless, and will be
prevented in the browsing code. :)
So; any NodeTree can become a "Goup Node" inside in a NodeTree. This
Group Node then works just like any Node.
To prevent the current code to become too complex, I've disabled
the possibility to insert Groups inside of Groups. That might be
enabled later, but is a real nasty piece of code to get OK.
Since Group Nodes are a dynamic Node type, a lot of work has been
done to ensure Node definitions can be dynamic too, but still allow
to be stored in files, and allow to be verified for type-definition
changes on reloading. This system needs a little bit maturing still,
so the Python gurus should better wait a little bit! (Also for me to
write the definite API docs for it).
What works now:
- Press CTRL+G to create a new Group. The grouping code checks for
impossible selections (like an unselected node between selected nodes).
Everthing that's selected then gets removed from the current tree, and
inserted in a new NodeTree library data block. A Group Node then is
added which links to this new NodeTree.
- Press ALT+G to ungroup. This will not delete the NodeTree library
data, but just duplicate the Group into the current tree.
- Press TAB, or click on the NodeTree icon to edit Groups. Note that
NodeTrees are instances, so editing one Group will also change the
other users.
This also means that when removing nodes in a Group (or hiding sockets
or changing internal links) this is immediately corrected for all users
of this Group, also in other Materials.
- While editing Groups, only the internal Nodes can be edited. A single
click outside of the Group boundary will close this 'edit mode'.
What needs to be done:
- SHIFT+A menu in toolbox style, also including a list of Groups
- Enable the single-user button in the Group Node
- Displaying all (visible) internal group UI elements in the Node Panel
- Enable Library linking and prevent editing of Groups then.
**** NEW: Socket Visibility control
Node types will be generated with a lot of possible inputs or outputs,
and drawing all sockets all the time isn't very useful then.
A new option in the Node header ('plus' icon) allows to either hide all
unused sockets (first keypress) or to reveil them (when there are hidden
sockets, the icon displays black, otherwise it's blended).
Hidden sockets in Nodes also are not exported to a Group, so this way
you can control what options (in/outputs) exactly are available.
To be done:
- a way to hide individual sockets, like with a RMB click on it.
**** NEW: Nodes now render!
This is still quite primitive, more on a level to replace the (now
obsolete and disabled) Material Layers.
What needs to be done:
- make the "Geometry" node work properly, also for AA textures
- make the Texture Node work (does very little at the moment)
- give Material Nodes all inputs as needed (like Map-to Panel)
- find a way to export more data from a Material Node, like the
shadow value, or light intensity only, etc
Very important also to separate from the Material Buttons the
"global" options, like "Ztransp" or "Wire" or "Halo". These can not
be set for each Material-Node individually.
Also note that the Preview Render (Buttons window) now renders a bit
differently. This was a horrid piece of antique code, using a totally
incompatible way of rendering. Target is to fully re-use internal
render code for previews.
OK... that's it mostly. Now test!

(WIP, don't bugs for this in tracker yet please!)
- New Panel "Layers" in Material buttons, allows to add unlimited amount
of materials on top of each other.
- Every Layer is actually just another Material, which gets rendered/shaded
(including texture), and then added on top of previous layer with an
operation like Mix, Add, Mult, etc.
- Layers render fully independent, so bumpmaps are not passed on to next
layers.
- Per Layer you can set if it influences Diffuse, Specular or Alpha
- If a Material returns alpha (like from texture), the alpha value is
used for adding the layers too.
- New texture "Map To" channel allows to have a texture work on a Layer
- Each layer, including basis Material, can be turned on/off individually
Notes:
- at this moment, the full shading pass happens for each layer, including
shadow, AO and raytraced mirror or transparency...
- I had to remove old hacks from preview render, which corrected reflected
normals for preview texturing.
- still needs loadsa testing!
