Import your 3D models

3D Data Formats available for import

You can import your own 3D assets into the R.Design app.
We currently support the following formats:

  • glTF

  • GLB

  • Datasmith

glTF format

glTF (GL Transmission Format) is a 3D file format that stores 3D model information in JSON format. The use of JSON minimizes both the size of 3D assets and the runtime processing needed to unpack and use those assets. It was adopted for the efficient transmission and loading of 3D scenes and models by applications.

For details, please see glTF file format


What is the difference between the GLB and glTF file?

There is a significant difference between what is a GLB and glTF. The GLB format is a version of the glTF file. The difference is that the GLB format is a binary file format while the glTF is based on JSON (JavaScript Object Notation). The GLB locates all of the elements of a 3D scene, including materials, node hierarchy and cameras in one single compressed file. In comparison, the glTF file requires external processing file formats, such as for textures, shaders and animation data. These external elements are stored in the glTF file, but each in a unique format (JPEG for textures, GLSL for shaders and BIN for animation data).

Therefore, the GLB is known as an autonomous file (everything is included in a single network) and the glTF as a non-autonomous file. The GLB is also 33% smaller in size than the glTF file, which makes it more efficient to use as it takes up less processing information. At Visao, we use the GLB file for its ease of use.

Step 1 Go to Import menu

You can see import menus for:

  • Item

  • Level (House or Room model)

Drag & Drop the asset you wish to import, or just simply click the menu so that you can select the asset from the Explore.

Step 2

Imported Assets are all listed here.

Step 3

Arrangement of items

  • Left click + Drag to place items

  • After a few seconds, the item appears in space.

Room (Level) display

  • Left Click

  • After a few seconds, the room will appear.

Pitch Black Room

Even after loading the imported Level, the screen may remain black.





The cause of the problem is most likely that the imported Level’s window glass material does not allow light to pass through.

To fix the issue, please take the following actions:

  1. Move your active camera and go outside the house













  2. Apply the clear glass material from R.Design “Basics” menu.
