1. Here's why

Version 8 and newer: You do not need to read this article as Lumion 8 (and newer) lets you remove selected OpenStreetMap buildings.

Version 7: Please read the following guidelines:

The bounding box of your model is used for calculating the volume that the model occupies in the scene. The bounding box is the turquoise wireframe box that surrounds selected models:

The OpenStreetMap function then "subtracts" this volume from the downloaded OpenStreetMap model, so that buildings, roads etc do not overlap your model:

That way you can easily create an in-fill project by inserting your model in the desired location.

1.1: If the bounding box of your Imported Model is too big, so that too much of the OpenStreetMap model is removed (for example if the model contains two houses far from each other), we recommend importing the model in separate parts.

1.2: An option to reduce the underlying terrain that can be seen is to paint the Lumion Terrain underneath the areas of the cut-out. Whilst not perfect it does help to reduce the obvious color differences.

1.3: To capture the colors of the OpenStreetMap next to the model, create a small tileable image of a single color that matches the OpenStreetMap element below the Imported Model:

Example of such a texture:

1.4: Add the texture to the Lumion Terrain texture tile for a spare slot:

1.5: Paint the Lumion Terrain where the jagged edges appear. This has the effect of 'merging' the background color so the jaggy edges can look a little less obvious than for example a green terrain background.:

1.6: Alternatively, if you do not need to see the underlying Lumion Terrain anywhere, just change the Landscape Texture in slot 1 to one of the primary colors of the OpenStreetMap model.
