# Scene & world building
### Step 1: Block in your environment
Use primitive shapes to define the scale and spatial layout of your scene. Focus on composition and silhouette.

*TIP: Monitor your performance while building. Keep an eye on the FPS counter in the top-left corner of the viewport to ensure the scene remains optimized.*
{% endhint %}
### Step 2: Add color with materials
Assign materials to your primitives to establish color and surface properties. Use distinct material assignments to differentiate functional areas or material types within the blockout.
### Step 3: Generate concept art
Capture a view of your blockout and use the integrated AI generator to visualize the final result of your environment.
### Step 4: Place your light source
Add a Directional Light to the scene to establish the primary lighting direction and mood.
### Step 5: Configure shadows
Enable shadows on your light source and assign shadow-casting to specific objects. Full Inspector names and limits: [How to use shadow](/the-editor/how-to-use-shadow.md).
1. Select the Directional Light. Turn **Cast Shadow** on.
2. Select the floor (or other ground). Turn **Receive Shadow** on.
3. Select each object that should throw a silhouette. Turn **Cast Shadow** on.

### Step 6: Enable post-processing
Refine the final visual output of your scene by enabling high-fidelity effects.
1. Open the **Post-Processing** settings panel.
2. Enable **Bloom** to add light bleeding and glow.
3. Enable **Ambient Occlusion** to add contact shadows in crevices.
Final visual polish with post-processing
### What you've done
You have established the layout, lighting, and visual baseline for your world. Place kit `.glb` files as Model Mesh Nodes next: [How to kitbash a level from mesh models](/the-editor/how-to-kitbash-a-level-from-mesh-models.md). Extra levels are more `.genesys-scene` files: [How to add and play a second scene](/the-editor/how-to-add-and-play-a-second-scene.md).

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://studio-docs.sandbox.game/the-editor/scene-and-world-building.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
