Terrain splitter 1.0 3D Tools 4.0 Community

Submitted by user Stand43; MIT; 2026-03-19

A lightweight Godot 4 editor add-on that takes a single, massive MeshInstance3D and seamlessly slices it into a grid of smaller, optimized chunks directly within the editor.

How to use:

Select any MeshInstance3D node in your scene tree.

Look at the top of your 3D Viewport (next to the Translate/Rotate/Scale tools) and click the new Split Terrain button.

A menu will pop up. Enter the number of chunks you want for the X and Z axes.

Check Make static bodies if you want collision shapes generated for the chunks (highly recommended for walkable terrain).

Click OK.

The addon will calculate the bounds, slice the triangles, re-index the vertices to save memory, and spawn the new chunks as children of your original mesh.
