Finally add a new property to the Environment settings in Blender. This depends on what meta information you would like to export with your model.Ħ. You could add more properties to the object as needed such as 'address.PostalCode: 0000AB'. Add a custom property to the empty object: (See step 3.1, choose 'String')

So in this example it would be 'Building'.ĥ. Add an empty object to the Lod2 Collection and rename it to the ' ID_of_object'. Click OK and change the value to 'Solid'.Ĥ. For non number values choose 'String' as type and name your property in the Property Name field. Finally change the value of the new lod to 2 instead of 1.ģ.4. Set the Max value to the value you want the property to have. Property name should be in this case 'lod'. Choose from the type dropdown 'Integer' if your property will be a whole number. To add properties correctly, click on the edit button to configure the attribute.ģ.2. So for this example the type would be 'Solid' and the lod would be '2'ģ.1. type: the_surface_type (Surface, MultiSurface, CompositeSurface and Solid are accepted).In the object properties add 2 new custom properties to your model: So for example a level 2 house model could be renamed as: 2: Buildingģ. The '2' represents the LoD and 'ID-of_object' represents the name of the object. Rename your model to the following specification: 2: ID_of_object.

Make sure that your model is part of this collection.Ģ. Rename your collection (name of the group the model is in) in the outliner to 'LoD2' by double clicking on it. (Consult screenshots for more clarification).ġ. For other levels, the workflow is the same. In this setup we will be using the Level of Detail 2. This helps reduce memory when a large area is displayed. Levels of Detail are primarily used in real time engines like the Tygron Platform to load the appropriate size model for the particular zoom level. 0 is the lowest resolution version of the model. Another important issue is the Levels of Detail that need to be setup. This consists of naming conventions and custom properties that need to be added to your model and Blender environment. There is a small setup needed in order to export your model succesfully to CityJSON.

Click on the checkbox next to it to activate the exporter.

After install the exporter will be available in the list.

Blender models for zip file#

Click on 'Install' in the top right and select the zip file which you have downloaded.ĥ. You can see a list of the add-ons which are available for Blender.Ĥ. In the preference dialog click on 'Add-ons'. Open Blender and go to Edit -> Preferences.ģ.

Visit and download the zip file from the green Code dropdown menu on the right side.Ģ. Its functionality was further developed for the needs of their MSc thesis 'An integrative workflow for 3D city model versioning'.ġ. This add-on was originally developed by Konstantinos Mastorakis (konmast3r) as part of a research orientation project for the MSc Geomatics programme of TU Delft. In order to export Blender models to CityJSON we first need to install the Up3date exporter and install it as an add-on in to Blender.

To learn more about Blender visit or (software) Blender is the free and open source 3D creation suite. Therefore, this article deals with exporting a Blender model to CityJSON so that it can be imported into the Tygron Platform via the CityGML importer. Depending on your own processes, this might require you to export a model from Blender first. You can import a CityGML file into the Tygron Platform to evaluate 3d city designs.
