The crash was caused by BVH traversal stack being overflowed.
That overflow was caused by lots of false-positive intersections
for rays originating on a non-finite location.
Not sure why those rays will be existing in the first place,
this is to be investigated separately.
This commit moves pre-SSE4.1 check to a higher level function
and enables it for all miroarchitectures.
It's too easy to miss at the bottom of the screen, and if the status bar is
collapsed critical messages may not be seen at all. There might be a better
looking solution, but for now this solves the main usability problem.
Seems there is something wrong with ternary operator
and type deduction.
Copying matrix to a variable with cleaner name seems
to be better solution than to force cast to an array.
The option WITH_C11 is gone, and C++ is defaulting to C++11 now,
so guess it's fine to assume we need C11 now.
This is technically what we use anyway, with all the re-definitions
of structs (like when we typedef anonymous struct in a header file
first, and them define it to a proper structure in implementation
file).
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.
I had to make the viewport navigation icons a bit smaller in the SVG since
the edges were being clipped off, we only support 16x16 icons currently.
They are a bit blurry because of this.
Move the weight paint drawing to the fragment shader. The shader
uses a texture that uses the U.coba_weight custom color band, or
an internal color band.
In addition to actual weights, the shader has to display two
alert colors: missing vertex group, and zero weight. The zero
weight alert has to be blended with regular weight colors,
so that a single alert vertex surrounded by weighted ones is
still visible.

New entry in the Add Object menu.
Opens a file selector and creates a new empty object from the selected image.
Previously more steps were needed to archieve the same.

This was caused by the object center being selected by the wireframe pass.
The wireframe pass is now only drawn if we search for the nearest surface.
This makes all wire objects (like non-meshes objects) higher priority than
mesh surfaces.
Previously copy and paste was handled within the same function using a mode switch, which is quite ugly in most cases.
This patch separates the function into two and splits up those in even smaller functions to increase maintainability.
Finally one new feature was added: You can copy from disabled fields now. (requested by hjalti)
