ArchAi3D_Qwen_Exterior_Navigation

If Exterior Focus is "stand here and shoot the subject," Exterior Navigation is "move through the scene" - approach the building, retreat from it, flyby past it, strafe across the courtyard. It's the exterior-specific sibling of the general Environment Navigator, and it's what you use to turn a single static exterior render into a sequence of frames that feel like a tour rather than a slideshow.

The panel

• preset - navigation patterns with an architectural flavor: approach_building is the default, plus the rest of the approach/circle/flyby family. Pick a preset or custom to drive it manually.
• scene_context - describe the outdoor scene ("modern glass building", "outdoor deck with furniture"). Same consistency advice as the whole family: the model can't navigate a space it doesn't think it's in.
• movement - forward (approach), backward (retreat), left/right (strafe), up/down (drone-style vertical).
• distance (1–20m) - how far the camera travels.
• rotation - none, left/right (pan), up/down (tilt), combined with movement for curved paths.
• speed - slow, normal, fast, smooth.
• debug_mode - prints the generated prompt.

Outputs

prompt, preset_description, and system_prompt (the v5.0 research-validated exterior-navigation system prompt for the encoder). Same three-wire pattern as every node in this family - prompt + system_prompt into an ArchAi3D encoder, and you're generating.

How it works

Pure prompt composition around distance-and-direction language: "approach the modern glass building, moving smoothly 10m forward." The movement, rotation and speed fields get woven into a single navigational instruction, and the presets are curated versions of those sentences tuned for exterior architecture (approach, circle, flyby) rather than interior rooms. The underlying bet - meters and named directions beat abstract geometry - is the same research finding the whole pack runs on, and it's the right one for Qwen Edit.

The honest take

This is a sequence-building node, and the sequences are only as good as the steps. A 20m approach in one frame is where exterior scenes fall apart - the model has to fabricate a lot of outdoor space between here and there, and "the" building can subtly become "a" building. The workflow that works: 3–5m per frame, several frames, then chain them for a walkthrough. The exterior nodes also benefit more than the interior ones from a strong scene_context, because outdoor scenes have less structure (no walls to anchor the geometry) - give the model landmarks to hold onto.

Install

Pack install, 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, find it under ArchAi3d/Camera/Exterior. You need Qwen-Image-Edit weights (quantized on consumer GPUs). And the same family physics apply: left/right is picture-relative, people in frame get moved instead of the camera, and direction is reliable while exact distance is approximate.
