This feature got lost with new auto-track API,
Added it back by extending frame accessor class. This isn't really
a frame thing, but we don't have other type of accessor here.
Surely, we can use old-style API here and pass mask via region
tracker options for this particular case, but then it becomes much
less obvious how real auto-tracker will access this mask with old
style API.
So seems we do need an accessor for such data, just matter of
finding better place than frame accessor.
It's a bit ugly but I couldn't find a better way to keep fast installs and
correct handling of switching between master and blender2.8 with different
lib directories.
- Derived-mesh drawing.
- All non UV members of TexFace structs.
MTexPoly is now redundant but keeping with a dummy member,
will check on complete removal later.
TexFace complicates the now more popular shading pipeline by having
per-face images, see: T51382 for details.
To keep the ability to select a per-material edit-image
(used with UV-mapping workflow), the material now stores an image
which will be set when changing images in edit-mode.
This is used as a bake-target when not using Cycles too.
This makes it possible to have an animated / procedurally generated mesh
that starts empty and obtains data in later frames.
Fixes the export of an empty mesh with an Ocean Modifier, as described in
issue T51351.
This allows you to put any kind of animation data on the mesh, and its
shape will be exported on each timekey. Note that this timekey is unrelated
to the animation data (so we don't export on each keyframe, for example).
A practical example is the addition of an animated custom property to
trigger the export of animated mesh data. The mesh data can then be created
from any source, like Python scripts.
Not only is this useful in itself, it also provides a workaround for one
of the two issues described in T51351.
This is written in a custom metadata key, so it isn't shown by utilities
like abcecho or abcls. However, it's still something that's useful to
have available.
Storing edit-mesh data as indices for passing
only to get back edit-mesh data.
This also complicated checks for real edges in tessellation tris.
Simpler to pass data directly.
Houdini writes vertex data in a different format than Blender does; Houdini
uses "face-varying scope", which means that the vertex colours are indexed
by an ever-increasing number over all vertices of all faces instead of the
vertex index.
I've also merged the read_custom_data_mcols() and read_mcols() functions,
because the latter was only called from the former, and the changes in this
commit would add yet more function parameters to pass.
A big chunk of code was copied between the if and else bodies. By using
a boolean to store whether the c3f_ptr or c4f_ptr should be used, the
in-loop condition is kept as simple as possible.
