Simple Blender Render now no longer renders to an intermediate directory.
This not only simplifies the script, but it also opens the door for
selective re-running of individual tasks.
In the old situation, where the intermediate directory was renamed to
the desired name in the last task, rerunning tasks would fail because the
directory they expect to exist no longer exists. This is now resolved.
The original idea behind this job type was that it would work equally
well for videos as for images, but that was never really well tested.
It's currently broken, so this commit removes video support altogether.
Remove the `blender_cmd` setting, and just hard-code it to `{blender}`.
The Blender add-on was already passing this string, and it's very unlikely
that people are already writing custom add-ons to pass something different.
It provided flexibility that was untested, so it's better to simplify
things.
Split "executable" from "its arguments" in blender & ffmpeg commands.
Use `{blenderArgs}` variable to hold the default Blender arguments,
instead of having both the executable and its arguments in `{blender}`.
The reason for this is to support backslashes in the Blender executable
path. These were interpreted as escape characters by the shell lexer.
The shell lexer based splitting is now only performed on the default
arguments, with the result that `C:\Program Files\Blender
Foundation\3.3\blender.exe` is now a valid value for `{blender}`.
This does mean that this is backward incompatible change, and that it
requires setting up Flamenco Manager again, and that older jobs will not
be able to be rerun.
It is recommended to remove `flamenco-manager.yaml`, restart Flamenco
Manager, and reconfigure via the setup assistant.
Add a new `abspath(path)` function to the add-on, for use in job type
settings. With this, the "simple blender render" job can support relative
paths for the "render output root" setting, and still have an absolute
final "render output path".
Blender cannot be told to only allow absolute path for an RNA property
(of type `string`, subtype `dir_path`), so as a workaround the final
`render_output_path` is now using `bpy.path.abspath()` to make the path
absolute.
This has as advantage that the render output path can be defined by artists
as a blendfile-relative path, and that it'll be resolved when submitting
the blend file.
Remove the `{ffmpeg}` variable from the default configuration, and its use
from the job compiler scripts. Now that the Worker can find its bundled
FFmpeg, it's no longer needed to configure its location on the Manager.
In the `simple-blender-render` job type settings, hide the `chunk_size`
setting from the web frontend, and show the `blendfile` setting instead.
The actual blend file being rendered is important to know, whereas the
chunk size can be inferred from the task names anyway.
Replace the Vue v2 webapp with a Vue v3 one, and embed the OpenAPI
client in the webapp itself (instead of being its own npm project).
- Vue v2.x -> v3.x
- Tabulator v4.x -> v5.1
- Moment JS -> replaced with Luxon JS
- Vue CLI/UI -> replaced with Vite
Compute render output path when evaluating job settings, which is done
within the Flamenco add-on, instead of in the job compiler script. This
allows the UI to show the render path, rather than it only being known
after the job has been submitted.
This might not be the best way to do things, but it is very flexible and
allows TDs to determine the behaviour in their own job compiler script.
It doesn't allow a preview of "this is what the final render path will be"
in the Blender GUI though.
The add-on code was copy-pasted from other addons and used the GPL v2
license, whereas by accident the LICENSE text file had the GNU "Affero" GPL
license v3 (instead of regular GPL v3).
This is now all streamlined, and all code is licensed as "GPL v3 or later".
Furthermore, the code comments just show a SPDX License Identifier
instead of an entire license block.
Add `subtype` and `editable` fields:
- `subtype`: to distinguish between regular strings, file paths, dir paths,
etc.
- `editable`: To indicate a setting should be editale after submitting the
job. Editing will trigger re-compilation of the job.
Each job compiler script now must define a `compileJob(job)` function,
which will be called by Flamenco when necessary.
This makes it possible to run the script without a job, and get other
exported symbols from it, such as metadata about which settings its job
type needs/exposes.
