Ellipsis value is internal ingredient only, to tag hidden _node_normalmap
'real' property as not yet initialized. Public node_normalmap accessor
should never ever have that value, it's either None or a valid node!
This reverts commit ce4cfbe108.
Obviously wrong 'fix', please do not touch other dev’s code, especially
in active/WIP area, when you do not fully understand it.
Fix broken behavior in case of texcoords mapping (we do need texcoords
node in all cases, then, even for UV coords...).
Use nodes by default when generating new write-allowed wrapper around a
material.
Do not try to find nodes in existing tree all the time, do it only once,
even for lazy-initialized nodes (through accessors).
Fix ugly spacing in property accessors (since it looks like some people
do not like a single 'block' with both getters, setters and prop
definition, at least use one sep line everywhere (and two sep lines to
separate properties)...
Best to give its actual name so it's clear that the Principled BSDF does
not have a diffuse color exactly, and does not have an alpha component.
Also image textures use UVs by default, so avoid creating a texture
coordinate node for that.
Loop triangles are tessellated triangles create from polygons, for renderers
or exporters that need to match Blender's polygon tesselation exactly. These
are a read-only runtime cache.
Tessfaces are a legacy data structure from before Blender supported n-gons,
and were already mostly removed from the C code.
Details on porting code to loop triangles is in the release notes.
Differential Revision: https://developer.blender.org/D3539
Currently some modes share tool keymaps, we might want to disable
this since it's confusing editing one thing in multiple places.
However this should be resolved in the tool definitions.
That new bpy_extras' node_shader_utils module is remotely based on
existing addons' cycles_shader_compat module. It has some key
differences though:
- It is based on Principled shader, instead of the noodle combination
of half a dozen simpler shaders.
- It does not do any value conversion (like e.g. clamping, which was
only suited for FBX). Any conversion/adaptation is to be done
by each IO add-on.
- It extensively uses accessors to offer:
- Easy read/write of values, hiding all the hairy noodly nodes
(principled shader helps a lot here).
- lazy creation of most nodes on accessing (when generating a
material), which avoids getting unused nodes in final shader.
- We only use Principled BSDF so far though, which means some features
supported by previous system are not yet implemented in new one.
Note that, even though we support 'exporting' side of things, this will
only work for a very specific (and basic) kind of shader. This will have
to be clearly explained in end-user documentation.
Also, that code has had some basic testing, but most certainly needs a
lot more refinement.
As proof-of-concept, OBJ IO script will be updated to use that new
system after that commit.
Consequences of new requirement to use named keywords parameters for our
RNA API... Hopefully fixed all other cases in that file as well, but
guess we'll find more of those in comming weeks. :|
Misleading name since it's between 0..1.
Use as a keyword argument to prepare for keyword only args.
Also document that leaving unset has special behavior.
This commit merge the full development done in greasepencil-object branch and include mainly the following features.
- New grease pencil object.
- New drawing engine.
- New grease pencil modes Draw/Sculpt/Edit and Weight Paint.
- New brushes for grease pencil.
- New modifiers for grease pencil.
- New shaders FX.
- New material system (replace old palettes and colors).
- Split of annotations (old grease pencil) and new grease pencil object.
- UI adapted to blender 2.8.

This is the result of nearly two years of development and I want thanks firstly the other members of the grease pencil team: Daniel M. Lara, Matias Mendiola and Joshua Leung for their support, ideas and to keep working in the project all the time, without them this project had been impossible.
Also, I want thanks other Blender developers for their help, advices and to be there always to help me, and specially to Clément Foucault, Dalai Felinto, Pablo Vázquez and Campbell Barton.
