Feeling a space before its built

A simple tutorial to export a Revit model into Unreal Engine 4 Videogames are no longer just for kids, over the past years they had become incredibly realistic and complex. In this article, we will explore how to use "Unreal Engine" (a game development environment ) to visualize and experience architectural models that are very far from being built.

The immersive characteristics of these new platforms bring users to a new level of sensations when they visit those spaces.

At Lagarsoft we specialize in combining technologies to produce awesome results, in this case, we will visualize Revit models using Virtual reality technologies so people can have a deeper understanding on how it feels to be in the space before the construction stage.

Technical details of our pipeline:

  • Revit 2019
  • Unreal Datasmith Exporter for Revit
  • Unreal Engine 4
  • Oculus Go
  • Python

Basically we export a Revit 3d View:

Into unreal engine using “Datasmith” plugin: Datasmith plugins allow exporting 3D models from many platforms into Unreal Engine.

From "good-quality" to Incredible Once all the data is on Unreal it is time to make it shine by replacing textures, adjusting lights, adding elements and correcting others.

“Automating the hustle” Fortunately Both unreal and Revit have great APIs so all the process described can be completely automated. As an example, we included a small snippet of how to replace material form the original texture to a photorealistic one.

Beyond rendering photos and recording videos, by using this technology, we can visit, interact, and experience a place allowing people to "feel it" and provide feedback in early stages of the development process.

Communication can be a very challenging task, and to make it effectively we can rely on computational power to help us to express and idea. Beyond Photographs and Video, the future will include Virtual reality and real-time data visualizations.


BIM is a process that involves many areas of knowledge and tools. We enable stakeholders to have updated information at every moment and in every place.
