A game ready 3D model is one you can import into an engine and use straight away, without fixing scale, orientation, materials or broken geometry first. This checklist covers what to look for and how models from Npx8 match each point, including what we do not do yet.
1. Real-world scale
The model should import at a sensible size, so a crate is roughly a metre tall and not a kilometre wide. Npx8 normalises each model's size and centres it before export, so assets typically need little resizing. Always check one asset against a reference object, such as a default cube, in your engine.
2. A sensible pivot and orientation
The pivot is the point the object rotates and sits around. For most props it should be at the bottom centre, so the object rests on the floor. Npx8 exports models upright and centred. Check where the pivot sits in your engine and move it to the base if your workflow needs it.
3. Reasonable triangle count
There is no single correct number; it depends on your platform and how close the camera gets. Props seen from a distance can be very light, hero objects can be heavier. Forge builds from simple parts, so its models typically stay light. If one feels heavy, simplify the prompt or use Refine.
4. Clean geometry
Look for holes, flipped faces and floating pieces. Forge checks each pass from several views and rebuilds the parts that look wrong, but always give an asset a quick look in the viewer before you download.
5. Materials that survive import
Materials should come through as standard, engine-friendly colours and textures. Npx8 paints a base colour onto each part and writes it into the GLB, so colours appear on import without extra setup.
6. The right file format
GLB is the best default: one file holding the mesh and its materials, supported by Godot, Blender and Unity through a glTF importer. OBJ is a useful fallback for tools that do not read glTF.
7. Collision
Engines need simple shapes for physics. Npx8 does not export separate collision meshes, so add a box or convex collider in your engine. Simple primitives are usually all a prop needs.
Honest limits
Npx8 does not rig or animate characters, and it does not unwrap UVs for hand-painted detail textures. It is built for props, environment pieces and stylized objects that you place, scale and light in your scene.
