# Build mode

Build mode is the art department. Construct the set, drop in props, set the time of day, import the client's CAD asset, generate a 3D mesh from a reference image. Anything to do with what's *in* the scene happens here.

{% hint style="success" %}
**The single most important Build-time action is attaching a reference image to your hero objects.** It's what takes a render from "approximately a car" to "the actual 2024 Bronco the agency briefed". For branded assets, custom geometry, hero products, and characters, this is the headline lever for professional fidelity. See [Image reference](/overview/concepts/image-reference.md).
{% endhint %}

## Locking down hero objects (start here)

* [**Image reference**](/overview/concepts/image-reference.md): the single biggest lever for brand-true output. Attach a photo of the actual product, vehicle, character, or storefront to its 3D object. Two paths: through the Object Details panel, or through the AI Composer with a one-line natural-language prompt.

## Working with objects

* [Asset library](/build/asset-library.md): over 5,000 greyboxing assets to drag in.
* [Working with objects](/build/working-with-objects.md): swap, recolor, lock, frame, delete.
* [Selection and grouping](/build/selection-and-grouping.md): marquee, parent attachments, the outliner.
* [Transform](/build/transform.md): position, rotate, scale, gizmo modes, smart snapping.
* [Object details](/build/object-details.md): name, description, image reference, LoRA per object.
* [Scene Outliner](/build/scene-outliner.md): the panel that lists every object in the scene.

## Building scenes

* [Environment](/build/environment.md): sun position, time of day, fog, terrain, grid.
* [Populators](/build/populators.md): procedural environment generators for cities, forests, crowds.
* [AI Composer](/build/ai-composer.md): prompt for whole environments instead of dragging assets.
* [Sets](/build/sets.md): save grouped objects and reuse them across projects.

## Bringing in your own content

* [Import your own models](/build/import-your-own-models.md): GLB, GLTF, DAE, FBX, PLY, OBJ, STL, USD. Smart Import with scale-fix.
* [Image to scene and shot](/build/image-to-scene-and-shot.md): start a project from a reference image.
* [Generate 3D Asset](/build/generate-3d-asset.md): text-to-mesh, image-to-mesh, multi-view-to-mesh.
* [LoRAs](/build/loras.md): upload a fine-tuned model for character or product consistency.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## 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://help.intangible.ai/build/build.md?ask=<question>&goal=<endgoal>
```

`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.
