Blender is a cross-platform, free, open-source 3D modeling tool used by a growing number of people worldwide. Blender can import many 3D formats out-of-the-box, and even more through the use of plugins.

In this guide, we export an example scene as OBJ. We preserve the names of the objects of the scene.

In Figure 1, “Blender example project”, you can see our example scene, with the Blender outliner displaying a list of objects on the right.

First, we export this scene as an OBJ file.

Have a look at the recommended export settings for the export:

Figure 3. Recommended export setting when exporting to OBJ. Select Objects as OBJ Groups and set the Up direction to Z Up.

The important settings are:

  • Objects as OBJ Group: select this to preserve object names in the Blender outliner in the output OBJ

  • Up Direction - Z Up: select Z Up to correctly rotate your object for LuciadFusion.

If we take the exported OBJ and plug it into LuciadFusion, we can create an OGC 3D Tiles service. When we preview this in LuciadRIA, we can perform selection operations, as shown in Figure 4, “The resulting dataset in LuciadRIA with selection and metadata enabled by default.”:
