Unpainted, uniform matte grey primer, like freshly printed resin terrain
Describe it or add a sketch to start
How this template works
Terrain has to stand on a table and survive dice rolls, so the template designs everything on one solid base first, then builds the 3D model.
1Open Image StudioStep 1 · Image StudioDesign the terrain
Image Studio draws your scene as a single terrain piece on a flat base, sized for 28–32 mm miniatures, with sturdy walls and nothing floating.

Tips for the best result
- Describe one piece, not a whole map: a tower, a well, a campsite.
- Mention the material and condition: mossy, ruined, burnt.
- FDM is fine for terrain; resin brings out fine stonework.
Do it yourself for more control
- Make a matching set by describing pieces with the same material, like "grey stone ruins".
- Use Ultra mesh quality for crisper bricks and planks.
- Scale it in Print Export so a door is about 30 mm tall for 28 mm miniatures.
Good to know
Pieces are solid; interiors and removable roofs need to be modelled separately.

My idea: A ruined stone watchtower with a broken staircase
Style: Grey primer
Base shape: Irregular
Follow these steps in order. The prompts and settings are the template's own, so use them word for word and only put my idea where it says {MY IDEA}.
1. Design the terrain
Call generate_image_nano_2_1 with aspect_ratio "1:1", resolution "1K", output_format "png" and this prompt:
"""
Terrain piece: {MY IDEA}. A single tabletop wargaming terrain piece sized for 28-32 mm miniatures, built on one flat irregular base with a gently textured ground, everything attached to the base with no floating parts, sturdy walls and props with no paper-thin details, open enough that miniatures can stand on or around it. The entire piece visible with generous empty margin, centered, three-quarter view from above. Isolated on a seamless pure white (#FFFFFF) background, soft even studio lighting, no shadows on the background, no miniatures, no text. Material: unpainted, uniform matte grey primer, like freshly printed resin terrain. Light and surfaces: soft, even, diffuse studio light from the front, and at most a soft satin sheen: no mirror-like gloss, no bright white hot spots or glare, and no reflections of lights, windows or surroundings.
"""
If I want to start from a sketch or reference image instead, call upload_image so I can hand it over, then call edit_image_gpt with the upload in images, quality "low", output_format "png" and this prompt:
"""
Turn the scene in the reference sketch into a tabletop terrain piece, keeping its layout and key features. A single tabletop wargaming terrain piece sized for 28-32 mm miniatures, built on one flat irregular base with a gently textured ground, everything attached to the base with no floating parts, sturdy walls and props with no paper-thin details, open enough that miniatures can stand on or around it.

2. Build the 3D model
Call generate_prism_3_1 with the task_id of the image from step 1 in images, texture_model "3.5", texture_quality "fast", geometry_quality "standard", pbr false, lighting_removal false.
3. Export
Export it for printing: call convert_model on the 3D model with output_format "3mf" (or "stl" if I ask for it), plus max_size and unit "cm" if I gave you a print size.
After each generation call, keep polling get_generation with its task_id until it completes, then show me the result with show_generation before you start the next step.Or automate it with the API
