This version is the "full" for them old/earlier unreal engine users.. i can output 8k(7680×4320) image & 4k 120fps video.
Twinmotion 2021.1 offers powerful new possibilities for creating, developing, and presenting your visualizations, cementing its place as an essential component of the entire archviz pipeline from first concept to advanced photorealistic experience, and as a fully connected member of the Epic Games ecosystem. In addition, with this release we continue our efforts to enhance existing features and workflows in response to customer feedback.

Bridge to Unreal Engine
A new plugin for Unreal Engine that enables you to import Twinmotion projects into the Unreal Editor. With this extended pipeline, an architect can communicate preliminary concept ideas-such as visually indicating the type of materials, lighting, context, and other project elements-in Twinmotion, and then pass the project on to a visualization specialist for further refinement in Unreal Engine, including accurate lighting and material scenarios, higher-quality visualization outputs, animations, and other advanced behaviors.

Once in Unreal Engine, you can add advanced functionality to your project, for example using the Variant Manager to present bespoke and customized design options.

Megascans in Twinmotion library
Epic integrated the Quixel Megascans 3D Assets and Surface categories into the Twinmotion asset library for easy browsing and access directly within Twinmotion projects. Assets are stored on the cloud until downloaded for use, reducing local storage requirements.

Datasmith Direct Link
Datasmith Direct Link now works with Revit, enabling you to aggregate multiple Revit files representing different stages.
