Rodin 3D Gen-2.5 - Image to 3D

Rodin Gen-2.5 is Deemos' newer, more configurable generation line, and this node is its image input: 1–5 reference images in, a 3D model out, with a mode switch that trades speed against polygon count and price. Where the older Rodin3D_Gen2 node is a fixed recipe, Gen-2.5 hands you a quality dial - Fast, Regular, or Extreme-High - and lets you choose your own adventure between rapid prototyping and a 2M-face monster.

The recurring caveat applies: this is a paid cloud API node (Comfy Org account + credits), and Rodin's newer tier is priced by what you ask for, not flat. The price badge reacts to your mode choice, so it's worth a glance before you queue.

How it works

You feed the node an image or a batch (up to 5), pick a mode, and the node uploads everything to Comfy's cloud, which forwards it to Rodin's Gen-2.5 API. Comfy polls until the task completes and downloads the result into your output folder as Rodin3D_Gen25_<uuid>/. The mode combo is a dynamic one: each branch adds its own controls. Fast targets 1K–20K faces for quick drafts; Regular is the balanced default with a tier picker (Low/Medium/High) and polygon presets; Extreme-High goes 20K–2M faces with optional is_micro micro-detail and a Quad/Raw mesh mode.

The inputs that matter

• images - 1–5 images. The tooltip has a real tip: the first image is used for materials when you feed multiple views.
• mode - the dynamic combo above. Start with Regular at Gen-2.5-High; drop to Fast when you're iterating on silhouettes, reach for Extreme-High only for finals.
• material - PBR, Shaded, All, or None (default Shaded). PBR buys you the game-engine maps.
• geometry_file_format - glb (default), fbx, obj, or stl. Pick your pipeline's native format up front.
• Optional goodies: hd_texture (high-quality texture enhancement), texture_delight (strips baked lighting out of textures), use_original_alpha (preserve image transparency), addon_highpack (4K textures and ~16x faces in Quad mode - this is the pricey add-on), plus bbox_width/height/length and height_cm to constrain the output size.

Output: a single model_file (FILE_3D) in your chosen format. No task ID, no chain - this node is a one-shot.

Common issues

The pricing gets people: Extreme-High and especially addon_highpack can multiply the base credit cost well past the older Gen-2 node's flat $0.40. Also, texture_delight is only useful if you plan to relight the asset - turning it on for everything just slows the job. And don't expect determinism from seed; as with the rest of the family it's a re-run control. For a free path, local Hunyuan3D nodes run on your own GPU, but Gen-2.5's quality ceiling is why the paid route keeps winning for production assets.
