Blender

3D modelling, animation, and rendering suite

Blender is a complete 3D creation suite covering modelling, sculpting, animation, simulation, and rendering, streamed here in a remote desktop session and backed by remote compute. It builds on the Void Desktop image — Blender launches maximized with the window decorations and taskbar hidden, so the viewport fills the screen.

Usage

1. Deploy

dxflow workflow create --identity blender hub://blender

# Start with defaults, or tune per run with --override
dxflow workflow start blender
dxflow workflow start blender \
    --override env.app.VNC_PASSWORD=my-strong-pass \
    --override env.app.TASKBAR=show

# Publish the web port on an HTTPS link
dxflow workflow start blender --link

2. Open the app

Open your browser at http://localhost:6082/vnc.html and enter the password you set in VNC_PASSWORD. Blender is already running and maximized. Port 5901 is also exposed for connecting a native VNC client. A start given --link publishes port 6082 at an HTTPS URL printed on the start line — open it at /vnc.html to reach Blender from anywhere.

3. Persist data

Anything under /volume persists across restarts — save your work there to keep it.

Notes

Set a strong VNC_PASSWORD; it defaults to dxflow, which every reader of this page knows.
The panel and taskbar are hidden by default so the viewport fills the screen. Set PANEL=show or TASKBAR=show to bring back the window decorations and taskbar.
Audio: off by default. Set AUDIO=on to stream desktop sound; tune with AUDIO_CHANNELS (1 or 2) and AUDIO_RATE (8000/16000/22050/32000/44100). The audio port is AUDIO_PORT (default 6100) — the client follows it, so to run two sessions on one host give each its own port by setting AUDIO_PORT and the matching audio port mapping together.
Rendering runs on the CPU here: the software OpenGL the desktop provides drives the viewport, and Cycles has no card to offload to. Give the step more cpu for heavier scenes.
