ArchAi3D_Qwen_Object_Rotation_Control

A 360° product turntable is the single most requested camera shot in e-commerce, and it's the one thing a single image edit can't do - which is why ArchAi3D_Qwen_Object_Rotation_Control ships with multi-step mode built in. Its default preset is product_turntable_360, and it's the pack's answer to "orbit the camera around the product without melting it."

The mechanism is the "orbit around" phrase, which the pack's Reddit-sourced research calls the single most reliable rotation instruction for Qwen-Edit - more dependable than "rotate 90 degrees," which the model reads about as precisely as you'd guess. You name the target, pick a direction, pick an angle, and the node writes the orbit prompt plus a system prompt that keeps the subject glued together while the camera travels.

The input that makes it special

multi_step_mode is the feature worth caring about. A single edit asking for 360° reliably produces a mush; asking for 8×45° steps, generating each one from the previous output, produces an actual turntable. Turn it on and set:

• steps - 8 is standard, 12 for detail, up to 24 for smooth video sequences. More steps means more passes, so it's also a time budget.
• angle - 1–360°, default 90. For full turntables, keep it on 360 with multi-step on.
• distance - close for product detail, medium standard, wide for context.
• reveal - a plain-text hint for what the rotation should show: "all sides", "details", "features", "back".

Outputs include the single prompt, a multi_step_prompts string (the per-frame sequence when multi-step is on), a frame_count integer telling you how many passes to expect, plus the standard rotation_description and system_prompt.

How it works

The node assembles a "camera orbit around [target] to the [direction] by [angle]° revealing [reveal]" instruction using the verified orbit pattern, and when multi-step is enabled it generates an ordered list of step prompts - 1/N, 2/N, up to 360° - designed to be chained through the encoder. Direction is right (clockwise) or left (counter-clockwise), and the pack's docs stress that left/right means picture-left/right, not the subject's perspective.

Installing it

This is one node inside ComfyUI-ArchAi3d-Qwen by Amir Ferdos (ArchAi3d). Standard install:

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

Restart. No models shipped - you load Qwen-Image-Edit yourself (GGUF-quantized is the realistic path; the 20B full-precision weights are brutal on VRAM).

Common issues

• The product mutates between steps. Because Qwen-Edit re-emits the whole frame, each step in a chain drifts - logos warp, handles move. Chain edits by feeding the previous output image in, and keep the system prompt connected.
• Angles stay approximate. Direction is consistent, degrees are vibes. Don't expect a mathematically exact 45°.
• Centered subjects win. Off-center products make the model invent rotation instead of orbiting. Center it first.
• Multi-step is slow. 8+ full Qwen-Edit passes per turntable adds up fast on a consumer card - plan the render.

For product turntables and building fly-arounds it's the node in this pack with an actual reason to exist over a hand-typed prompt: the step chaining is the part nobody wants to write manually.
