extapps 0.1.6

Standalone Switchboard panels for content-pipeline workflows (map compositing, photogrammetry, Substance Painter automation, texture conversion, mesh conversion).

Standalone Switchboard panels for content-pipeline workflows.

extapps

Each app is a self-contained subpackage that registers itself with uitk's ExternalAppHandler via the uitk.external_apps.in_process entry-point group. Hosts (tentacle, mayatk, etc.) discover and launch them automatically — no host-side imports required.

Tools

Tool	Purpose	Engine	Docs
map_compositor	Multi-layer texture compositing	pythontk.img_utils.map_compositor	→
metashape_workflow	Agisoft Metashape photogrammetry automation	bundled (SDK-specific)	→

Install

pip install extapps

Launch (standalone)

python -c "from extapps.map_compositor import MapCompositorUI; MapCompositorUI().show(pos='screen', app_exec=True)"

Launch (from a host)

Hosts that load uitk's ExternalAppHandler discover apps automatically:

sb.handlers.external_app.launch("map_compositor")

Dependencies

• pythontk — domain logic
• uitk — UI framework
• qtpy — Qt abstraction

The metashape_workflow tool additionally requires the Agisoft Metashape Python module to be importable (installed alongside Metashape itself). The substance_workflow tool requires an Adobe Substance 3D Painter install (auto-detected) to launch sessions.
