--- Changes to File Output node ---
* Flat layer names in EXR multilayer files.
For a socket with name "AAA" the previous resulting EXR layer name would be "AAA.AAA", i.e. the render layer as well as render pass would use the socket name.
Now the "render_layer.render_pass" scheme is ignored in multilayer files, socket names are directly written to EXR layers (EXR layer name is "AAA" in this example). If sockets should have a notion of "render layer" this can still be achieved by explicitly adding a separator, e.g. "AAA.BBB". When loading such layers into a Blender Image struct, the name is interpreted as a "render_layer.render_pass" again (although the image node does not care about it, see below).
* Socket sub-paths (for singlelayer) or layer names (for multilayer) are stored in dedicated string variables in the socket storage data. This way the RNA can define precise string subtypes (PROP_FILEPATH) and length. The file/layer slots are defined as separate structs with own name properties in the RNA as well, so they can be used nicely with the list template.
* Ensure unique socket paths/layer names to prevent overwriting of files and layers respectively.
--- Changes to Image node ---
* Loading multilayer OpenEXR files has improved layer name splitting into render layer + render pass names now. This properly supports arbitrary EXR layer names now.
Example:
OpenEXR layer name: AAA.BBB.CCC
is split into
Render layer name: AAA.BBB
Render pass name: CCC
If the layer name has no '.' separators the render layer name is empty.
* Image node ignores the selected render layer in the image user data. Instead all existing layers are displayed at the same time by combining the render layer names with render pass names again, to reconstruct the original EXR layer name. This avoids the problem that render layers with empty name are not selectetable in the dropdown and allows using all image layers at the same time without duplicating the node.
This was originally reimplemented as part of the socket selection feature, but since selecting a socket necessarily also selected the owning node, it messes with the manual user selection of nodes too much (and doesn't add any additional usability).
* Removed the struct_type identifier from sockets completely. Any specialization of socket types can be done by using separate collections in RNA and customized socket draw callbacks in node type. Sockets themselves are pure data inputs/outputs now. Possibly the sock->storage data could also be removed, but this will change anyway with id properties in custom nodes.
* Replaced the direct socket button draw calls by extra callbacks in node types. This allows nodes to draw sockets in specialized ways without referring to the additional struct_type identifier. Default is simply drawing the socket default_value button, only file output node overrides this atm.
* File output node slots now use a separate file sub-path in their storage data, instead of using the socket name. That way the path is an actual PROP_FILEPATH property and it works better with the UI list template (name property is local to the data struct).
* Node draw contexts for options on the node itself and detail buttons in the sidebar now have an extra context pointer "node" (uiLayoutSetContextPointer). This can be used to bind operator buttons to a specific node, instead of having to rely on the active/selected node(s) or making weak links via node name. Compare to modifiers and logic bricks, they use the same feature.
* Added another operator for reordering custom input slots in the file output node.
- Added new dtaablock called Mask which might be re-used in any area.
Currently editing of masks happens in clip editor and they might be used in
compositor nodes only.
- Added new mode to clip clip editor to interact with masks.
Implemented basic tools to create shapes, splines and points. Also implemented
idea of UW points for feather which means feather points are have got U
coordinate along spline (which is measured from 0 to 1) and W is it's weight
meaning distance from main spline.
- Spline points might be parented to movie tracks.
Interface for this isn't best yet.
- Rasterisaztion of masks happens in compositor node (Input -> Mask)
Input image of this ode is used as reference for mask resolution.
Currently all splines of all shapes are rasterizing independently which
means shapes with holes are not supported.
Also feather rasterization is not implemented.
Rasterized was implemented by Pete Larbell, thanks!
Do not consider this is something finished, there's still lots of things to
be done (especially from interface and usability points of view).
- Make sure functions are named in way BKE_<object>_<action> (same way as RNA callbacks)
- Make functions which are used by mball.c only static and remove their prototypes
from public header file.
Further cleanup is coming.
This feature did have a number of flaws and caused some controversy, so removal is the better option. Hiding nodes without prior connections would just hide all the sockets, leaving an unusable node. Better way is to use the ctrl+h shortcut to explicitly hide unused sockets when necessary.
* Drag'n'drop translation in Outliner
* "Execute" button in file window
* "Labels" of spacing elements, in multi-column enums
* A glitch with nodes "Value to RGB", they where called "ColorRamp" in node_type_base() call. This is not definitive, though, as it appears that UI node names are determined by this call, while it should be by "defines" in rna_nodetrre_types.h, I guess... Anyway, not good to have such things in two different places!
Also moved default context name under BLF_translation.h, much better to have those all in one place, accessible from whole Blender code!
* Improved checks for Grease Pencil and Active Node panel, so the panel only gets shown when there is valid data, rather than showing the empty panel.
Thanks to Lukas Tönne for some help! :)
* Remove some non used *_button_register functions, panels are done in python.
* Remove do_node_region_buttons, was not used anymore.
Fix:
* Only show Grease Pencil panel in the Node editor, when there is a valid nodetree.
--debug
--debug-ffmpeg
--debug-python
--debug-events
--debug-wm
This makes debug output easier to read - event debug prints would flood output too much before.
For convenience:
--debug-all turns all debug flags on (works as --debug did before).
also removed some redundant whitespace in debug prints and prefix some prints with __func__ to give some context.
*Add menu is now translated.
*Nodes' title is now translated.
*Nodes' sockets' labels are now translated.
However, about the last point, and unless I’m mistaking, we’ll have to add the "i18n tag" N_() to all sockets' names, in the input/ouput templates declaration, in all nodes' files, as those sockets are collections created at runtime, I think po-generating script has no way to access that from bpy.types... Quite a piece of (borring) work. :/
