ComfyUI-Domemaster-Outpaint

Turn flat video into fulldome / planetarium shows with ComfyUI: outpaint a normal perspective shot into an immersive hemisphere and render it as a domemaster — the standard fulldome delivery format (square frame, circular 180° fisheye) — with tilted-venue presets.

The workflow

[Load Video] → [Rectilinear → Equirect] → outpaint (LTX2.3 VR-Outpaint)
             → [Source Composite] → [Equirect → Domemaster] → save

The projection and finishing nodes come from the companion pack ComfyUI-VR-Outpaint-Tools — install both. This pack contributes the dome-side rendering.

Two ways to run the pipeline:

• Full 360 master: outpaint a standard 2:1 equirect, then render the dome from it (rear hemisphere is simply not shown).
• Square hemisphere (recommended for dome-only delivery): a hemisphere is exactly the center square of an equirectangular projection — an equirect spanning ±90° in both axes covers the dome completely, and its square boundary maps onto the dome rim. Set canvas_hfov_deg=180, canvas_vfov_deg=180 on a square canvas in Rectilinear → Equirect, disable wrap/seam nodes (a hemisphere has no wrap seam), set wrap_w=false on Source Composite, and input_hfov_deg=180, input_vfov_deg=180 here. Nothing is generated outside the dome — at equal generation cost, twice the pixels land on the dome (√2× the angular resolution per axis).

Node: Equirect → Domemaster (fulldome render)

Renders a domemaster from an equirectangular panorama. By default the dome is aimed at the canvas center — exactly where Rectilinear → Equirect places the source footage — so the original video sits at the dome center and the outpainted content fills out to the rim. The equirect wrap edge (yaw 180°) is more than 90° from the aim and never appears in the output. Sampling is wrap-aware, so off-axis aims are safe too.

| Input | Description | |---|---| | image | Equirect IMAGE batch (the finished panorama) | | size | Output square size, e.g. 2048 or 4096 | | fov_deg | Dome field of view (default 180) | | dome_tilt | Venue preset: 0 (flat dome — video straight overhead at dome center) or 15 / 20 / 25 / 30 for tilted venues — pitches the aim up by the tilt so the source lands at the audience's natural forward gaze (the sweet spot between dome center and the front springline) | | yaw_deg / pitch_deg | Manual aim offset on top of the tilt preset. pitch 90 = classic zenith-centered domemaster with the full horizon at the rim | | roll_deg | Rotate the dome image about its center (which direction is "front") | | interp | bicubic (default) or bilinear | | input_hfov_deg / input_vfov_deg (optional) | Angular span of the input canvas (default 360 / 180). Set both to 180 for a square-hemisphere input |

Pixels outside the fisheye circle are black. Keep the equirect as your master and render the domemaster as a delivery format.

Install

cd ComfyUI/custom_nodes
git clone https://github.com/Burgstall-labs/ComfyUI-Domemaster-Outpaint
git clone https://github.com/Burgstall-labs/ComfyUI-VR-Outpaint-Tools   # companion pack

Restart ComfyUI. The node appears under 360/dome. No dependencies beyond the torch runtime ComfyUI already uses.
