1. Here's how
There are two ways to work with terrains in Lumion:
- Use the built-in terrain in Lumion (Lumion Terrain).
- Import your own terrain model (Imported Terrain).
2. The built-in terrain in Lumion
The editable part of the Lumion Terrain is a 2000x2000m square centered at 0,0,0. It is not possible to change the height or paint the landscape outside this area. The height of the terrain fades to 0m over the last 50m of the edges of the 2000x2000m square in order to blend in with the flat terrain outside the editable area.
2.1: You can import and export terrains as a greyscale Heightmap texture via the Load Terrain Map function:
Lumion 7 and newer:
Lumion 6.5.1 and older:
2.2: If you want to import a Terrain Map (known as a Heightmap texture) from a 3rd party application, please use these guidelines to prepare the texture:
- The resolution of the Heightmap texture should be 1024x1024 pixels. The innermost 1000x1000 pixels are used for the 2000x2000m editable part of the terrain. The outermost 12 pixels along the edges are not used. Each pixel of the Heightmap texture corresponds to 2x2m on the editable part of the Lumion Terrain.
- The color black is equal to a terrain height of 0m and the color white is equal to a terrain height of 200m. Each greyscale step (from RGB = 0 to RGB = 255) is equal to a terrain height of 0.78125m.
2.3: There's more information about Heightmaps in this article:

3. Import your own terrain model
3.1: Alternatively, import your model in Lumion and mark it as a terrain.
Context Menu -> Click on the Object Icon -> Extra -> Mark as terrain -> On
3.2: Then assign a Landscape Material to it, so that the model uses the same Landscape Textures as the Lumion Terrain:
3.3: When you paint your model with the Landscape Textures, the Lumion Terrain below your model will also be painted - and vice versa. Please note that you can only paint the model as long as it's inside the the editable part of the Lumion Terrain, i.e. a 2000x2000m square centered at 0,0,0:
3.4: You can't use the terrain tools to lower/raise the terrain of an Imported Model that has been 'marked' as a terrain. However, a model 'marked' as a terrain does have other advantages:
- When you click on the Set eye level button while editing a Clip or a Panorama location, the camera will measure the distance from the Imported Model that you have 'marked' as a terrain (instead of only measuring the distance from the Lumion Terrain).
- When you hold down CTRL to place 10 objects at a time in Build Mode or when you hold down the ALT key to copy selected models, all of the models will be placed on the Imported Model that you have 'marked' as a terrain (instead of on the Lumion Terrain below it).
- Please note that 'marking' an Imported Model as a terrain will require more system memory for storing additional collision data, so use this function sparingly if your Imported Models are very complex. When you move a lot of objects, performance may also deteriorate if you have marked a lot of complex Imported Models as terrains.
