How to - Use AI 3D Model Generators with Dungeon Alchemist

Popular AI 3D Model Generators

• Meshy — Generate 3D models from text or images. Offers texture generation and supports multiple export formats including OBJ and FBX.
• Tripo — Create 3D assets from single images or text descriptions. Good for quick prototyping and concept validation.
• CSM (Common Sense Machines) — Image-to-3D with strong results for objects and scenes.
• Luma AI — Photorealistic 3D captures and generations with excellent texture quality.
• Rodin — Text and image to 3D with a focus on game-ready assets.

Step 1: Generate Your Model

1. Choose an AI generator (Meshy and Tripo are great starting points).
2. Enter a text prompt or upload a reference image.
3. Wait for the AI to generate the model — this usually takes seconds to a few minutes.
4. Review the result. If it is not right, refine your prompt and try again.

Step 2: Download and Import into Blender

1. Download the generated model in OBJ or FBX format.
2. Open Blender and start a new project.
3. Import the model via File → Import → OBJ/FBX.
4. The model may appear very large or very small — this is normal for AI-generated assets.

Step 3: Clean Up in Blender

AI-generated models often have issues that need fixing before import into Dungeon Alchemist:

• Scale the model — AI models often import at wildly incorrect scales. Use the N-Panel (press N) and adjust the Scale values so the model fits within Dungeon Alchemist's grid.
• Apply transforms — Press Ctrl + A and choose All Transforms to freeze the scale, rotation, and location.
• Reduce polygon count — AI models can be extremely high-poly. Use the Decimate modifier or Nightvision's addon to bring the poly count down.
• Check for inverted normals — In Edit Mode, select all faces and use Mesh → Normals → Recalculate Outside to fix any flipped faces.
• Merge duplicate vertices — Use M → By Distance in Edit Mode to clean up overlapping vertices.
• Check texture size — AI generators often output 4K textures. Resize them to 1K or 512 to keep file size under Dungeon Alchemist's recommended limit.

Step 4: Export as FBX for Dungeon Alchemist

1. Make sure your model is selected (it will have an orange outline).
2. Go to File → Export → FBX.
3. In the export settings, check Selected Objects.
4. Under Object Types, make sure only Mesh is selected.
5. Uncheck Animation unless your asset is animated.
6. Choose your save location and click Export FBX.

Step 5: Import into Dungeon Alchemist

1. Open Dungeon Alchemist and launch the Asset Importer.
2. Import your cleaned FBX file following the Asset Importer workflow.
3. Adjust the collision boxes if needed.
4. Save and upload to the Workshop if you want to share it.

Common Issues and Fixes

• Model is too big or too small in DA — The scale was not applied in Blender. Always press Ctrl + A → All Transforms before exporting.
• Textures are missing in DA — Make sure textures are packed into the file or exported alongside the FBX. Some AI generators export textures separately.
• Model looks black or weird in DA — Check for inverted normals in Blender and recalculate them. Also verify the material uses a Principled BSDF shader.
• File is too large — Decimate the mesh and compress/resize textures. See the size reduction guide.

Recommended Workflow Summary

1. Generate model with Meshy, Tripo, or another AI tool.
2. Download as OBJ or FBX.
3. Import into Blender.
4. Scale, apply transforms, and clean geometry.
5. Reduce polygons and texture sizes.
6. Export as FBX with correct settings.
7. Import into Dungeon Alchemist Asset Importer.
