ArchAi3D_Qwen_Exterior_Focus

The exterior camera nodes are the pack's answer to a very specific interior-design problem: you've designed the outdoor deck and you need a hero shot of the furniture on it, or the entrance, or the garden fountain - but from the right spot, at the right distance. Exterior Focus is the "position the camera in front of a target outdoors" node. Its default preset name even advertises the use case: outdoor_furniture_closeup.

The panel

• preset - focus targets like outdoor_furniture_closeup, or custom for manual control. Presets pre-fill the positioning parameters.
• prompt_style - the interesting one, and it's a genuine choice with research behind it. vantage_point is marked as the QWEN Guide's ⭐⭐⭐⭐⭐ verified pattern; zoom is the "user-tested real-world pattern." The tooltip says both work - the vantage-point phrasing positions the camera as a viewpoint, the zoom phrasing frames the change as a camera zoom. Worth trying both on your subject and keeping the one the model honors better.
• scene_context - describe the outdoor scene ("wooden deck with outdoor furniture on the right side"). The pack says it improves consistency, and it does - give the model the layout before asking it to move.
• custom_target - what to focus on when preset is custom: "the outdoor furniture on the deck", "the entrance door", "the garden fountain".
• direction - where to stand relative to the target (front = directly in front).
• distance (0.5–20m) - the spacing. Tooltip guidance is honest: smaller = closer/more intimate, larger = more context.
• height - face_level (standard), elevated (bird's eye), ground_level (worm's eye).
• auto_facing (default on) - automatically face the target to keep it centered. The recommended setting.

Outputs

prompt (for the encoder), preset_description (what the focus preset does), and system_prompt - the v5.0 "research-validated" system prompt for exterior focus, designed to keep the model preserving the outdoor scene while repositioning the camera.

How it works

Distance-first camera instruction: "position the camera at face level, 2.5m in front of the outdoor furniture, facing it." The research foundation here - and it's the same insight running through the whole pack - is that distance-based positioning in meters is more reliable for Qwen Edit than degree-based rotations, because the model handles spatial language ("2.5m to the left") better than geometry. The prompt_style toggle then decides whether that positioning is framed as a vantage point or as a zoom, which are the two phrasings that survived community testing.

When to reach for it

Exterior shots with a clear focal subject: deck furniture close-ups, entrance shots, garden features, product-on-the-patio hero shots. It's narrower than the generic focus cameras - it's exterior-flavored with exterior system prompts - so if your shot is inside, use one of the main camera nodes instead. Pair the outputs with an encoder and a Qwen Edit model, and if you're shooting a series, keep distance small between frames for smoother consistency.

Install

Same pack, once:

cd ComfyUI/custom_nodes
git clone https://github.com/amir84ferdos/ComfyUI-ArchAi3d-Qwen.git
cd ComfyUI-ArchAi3d-Qwen && pip install -r requirements.txt

Or ComfyUI Manager → "ArchAi3d Qwen". Restart, then it's under ArchAi3d/Camera/Exterior. You need the Qwen-Image-Edit weights (quantized on consumer GPUs). Gotcha: large distances on a wide outdoor scene are where Qwen drift bites hardest - the further the camera "moves," the more the model invents between here and there. Keep hops modest.
