Resizing a Terrain Heightmap - Lumberyard User Guide

Resizing a Terrain Heightmap

Open 3D Engine (O3DE), the successor to Lumberyard, is now available in Developer Preview. Download O3DE or visit the AWS Game Tech blog to learn more.

Resizing the terrain heightmap involves changing the resolution of your heightmap. Terrain size is determined by multiplying heightmap by meters per texel. When resizing, this value should not exceed 4096x4096 meters.

Meters per texel is the distance in meters between two vertices on the grid. So a value of two means there is a grid point every two meters. You can use larger values to create a larger terrain, but it is less detailed for the same heightmap resolution.

To resize a heightmap

  1. In Lumberyard Editor, click Game, Terrain, Resize Terrain.

  2. For Heightmap Resolution, select the desired value.

  3. For Meters Per Texel, select the desired value.
