 ## 3.6 - in development
 
+- Change the name of the add-on from "Flamenco 3" to just "Flamenco".
 - Add `label` to job settings, to have full control over how they are presented in Blender's job submission GUI. If a job setting does not define a label, its `key` is used to generate one (like Flamenco 3.5 and older).
 - Add `shellSplit(someString)` function to the job compiler scripts. This splits a string into an array of strings using shell/CLI semantics.
 - Make it possible to script job submissions in Blender, by executing the `bpy.ops.flamenco.submit_job(job_name="jobname")` operator.
 - Security updates of some deendencies:
   - [GO-2024-2937: Parsing a corrupt or malicious image with invalid color indices can cause a panic](https://pkg.go.dev/vuln/GO-2024-2937)
+- Web interface: list the job's worker tag in the job details.
+- Ensure the submitted scene is rendered in a multi-scene blend file.

+title: Built-in Job Types
+weight: 10
+---
+
+Flamenco comes with built-in job types that are used for most common tasks. Currently, there are two of them:
+
+- Simple Blender Render
+- Single Image Render
+
+## Simple Blender Render
+
+This built-in job type is used for rendering a sequence of frames from a single Blender file, and potentially creating a preview video for compatible formats using FFmpeg. This job type is suitable for straightforward rendering tasks where one needs to render a range of frames and potentially compile them into a video. Note that this job type does not render into video formats directly, so the output format should be FFmpeg-compatible image formats.
+
+The job type defines several settings that can be configured when submitting a job:
+
+- `Frames` _string, required_: The frame range to render, e.g. '47', '1-30', '3, 5-10, 47-327'. It could also be set to use scene range or automatically determined on submission.
+- `Chunk Size` _integer, default: 1_: Number of frames to render in one Blender render task.
+- `Render Output Root` _string, required_: Base directory where render output is stored. Job-specific parts will be appended to this path.
+- `Add Path Components` _integer, required, default: 0_: Number of path components from the current blend file to use in the render output path.
+- `Render Output Path` _non-editable_: Final file path where render output will be saved. This is a computed value based on the `Render Output Root` and `Add Path Components` settings.
+
+By using this job type, you can easily distribute Blender rendering tasks across multiple workers in your Flamenco setup, potentially saving significant time on large rendering projects.
+
+## Single Image Render
+
+This built-in job type is designed for distributed rendering of a single image from a Blender file. It splits the image into tiles, renders each tile separately, and then merges the tiles back into a single image. This approach allows for parallel processing of different parts of the image, potentially speeding up the rendering process.
+
+Currently, the job type supports composition, as long as there is one single `Render Layers` node. The job type does not support `Denoising` node.
+
+The job type defines several settings that can be configured when submitting a job:
+
+- `Tile Size X` _integer, default: 64: Tile size in pixels for the X axis, does not need to be divisible by the image width.
+- `Tile Size Y` _integer, default: 64: Tile size in pixels for the Y axis, does not need to be divisible by the image height.
+- `Frame` _integer, required_: The frame to render. By default, it uses the current frame in the Blender scene.
+- `Render Output Root` _string, required_: Base directory where render output is stored. Job-specific parts will be appended to this path.
+- `Add Path Components` _integer, required, default: 0_: Number of path components from the current blend file to use in the render output path.
+- `Render Output Path` _non-editable_: Final file path where render output will be saved. This is a computed value based on the `Render Output Root` and `Add Path Components` settings.
+
+Choosing the right tile size is crucial for performance. Too small tiles might increase overhead, while too large tiles might not distribute the workload effectively.

+## Absolute vs. Relative Paths
+
+Blender can reference assets (textures, linked blend files, etc.) in two ways:
+
+- by **relative path**, like `//textures\my-favourite-brick.exr`, which is relative to the blend file, or
+- by **absolute path**, like `D:\texture-library\my-favourite-brick.exr`, which is the full path of the file.
+
+When an asset is referenced by an absolute path, **Flamenco assumes that this
+path is valid for all Workers, and will not copy those assets to the shared
+storage.** This makes it possible to store large files, like simulation caches,
+on the shared storage, without Flamenco creating a copy for each render job.
+
+{{< hint type=Warning >}} On Windows it is not possible to construct a relative
+path to an asset when that asset is no a different drive than the main blend
+file. If you still want Flamenco to copy such assets, there are two workarounds:
+
+- Move your asset libraries to the same drive as your Blender projects.
+- Use [symbolic links][symlinks-guide-windows] to make your assets available at
+  a suitable path.
