Terrain3D 1.1.0, published on 30 October 2026, adds generated C# bindings, an ocean mesh and shader, texture displacement and ambient-occlusion texture support. The terrain add-on lists Godot 4.5–4.8+ compatibility. That is plugin compatibility, not a claim that Godot 4.8 itself is stable.
Check code as well as terrain data
The maintainer's API migration notes flag a consequential change: get_height() no longer interpolates. The new get_surface_height() includes interpolation, region blending and ground level for a rendered-surface result. Audit scripts that use height queries for placement or movement rather than assuming old behavior remains.
The same notes cover renamed methods and reordered texture-filtering enum values. Read the complete list before adapting custom integrations.
Follow the upgrade path on a copy
Our recommendation is to back up the project first. The official instructions say to close Godot and replace the old add-on directory, not simply overlay files. Check the documented data-conversion path: very old versions may need intermediate upgrades.
Do not equate improved export support with production readiness everywhere. Mobile and web remain experimental; web exports are described as very experimental. The platform guide also leaves full Metal support uncertain. Test the actual target device and renderer before committing a release schedule.
The software is MIT-licensed, with copyright and permission notices required for copies or substantial portions. We have not installed the add-on, measured performance or tested an export; this is a source-based upgrade checklist.
