Phasing and Scene States

An introduction to phasing and scene states.

A typical construction project can have many phases. From pouring the foundation, to creating the rough framing, through to installing flooring and finishing the exterior, each of these phases are executed—either one after the other or simultaneously—at a specific point in the timeline of a project. To view each of these phases and visualize the work progression over a period of time, you can use the Phasing tool and scene states.

How It Works

In Twinmotion, phasing and scene states are created in two distinct tools, but both have similar functionalities. You can use phasing and scene states to:

  • Break down the phases of a construction project into segments and then show the progression of the work by gradually revealing each phase from start to finish.

  • Create and compare variations of the same project or scene. Scene states are like snapshots that you take of a scene. Each one can have its own lighting and objects.

When you create phasing groups or scene states, you use the Scene graph to show and hide elements of the scene. Each phase or scene state that you create contains only those elements of the scene that you want to show.

The Phasing tool can be used to create time-lapse videos. Scene states can be applied to images, panoramas, and in the keyframes and parts of videos.

Showing the Evolution of a Construction Project

The Twinmotion Library contains several construction sets and assets such as excavators, building materials, cranes, and construction workers. These assets can be added to your scene to illustrate the progression of a construction project. For example:

Phase 1: To illustrate the start of a project, you can create a first phase or scene state that shows the terrain only, and then add an excavator from the Library to the scene.

Phase 2: In the next phase or scene state, you can show progress by removing the excavator and adding other construction assets from the Library such as construction workers and equipment.

Phase 3: In the next phase, you can show the concrete slab of the structure by making it visible in the Scene graph.

Final phase: In each subsequent phase or scene state that you create, you can gradually reveal elements of the scene, until the final version of the project is revealed in the last phase or scene state.

Below is an example of how you can use phasing to show the different construction phases of a project in a video.

Showing Variations in a Scene

You can use scene states and phasing groups to present variations of the same project. For example, you might want to show or compare multiple versions of the same interior scene but with different lighting and objects. Instead of recreating the entire scene for each variation, you can create and save multiple scene states.

Each scene state uses the same Twinmotion scene, but each one can have its own lighting and object visibility status. These scene states can be saved and applied to the scene, and to videos, images, and panoramas. This makes it easier to view and compare variations between versions of the same scene.

Below is an example of how you can show variations of the same scene in a video by using scene states and phasing groups.
