Roblox Studio supports importing both .fbx and .obj file formats. When exporting AI-generated models from Neural4D Studio, we recommend choosing FBX because it can contain embedded textures and animation data, reducing manual setup time.
To get your AI models into your Roblox environment, use the built-in 3D Importer tool:
Roblox imposes a strict limit of 10,000 triangles per mesh. High-fidelity AI models often exceed this limit. Follow these steps to optimize your assets:
| Optimization Step | Action Required |
|---|---|
| Polygon Reduction | Use Neural4D's AI Retopology tool or Blender's Decimate modifier to reduce the triangle count below 10,000. |
| Collision Fidelity | Change the CollisionFidelity property of your MeshPart in Roblox to Box or Hull to improve physics performance. |
| Scale Adjustment | Resize the model in Roblox using the Scale tool or adjust the dimensions in the Import 3D preview window. |
If your model imports successfully but appears gray, you need to manually configure the PBR materials:
