Mesh to Terrain



Thanks for using Mesh to Terrain! Don't forget to leave a review on the store page if you liked it, this helps us a lot!

Mesh to Terrain is a tool for easily and quickly converting a 3D terrain model created in 3ds Max, Terragen or any other editor to Unity Terrains. Also, Mesh to Terrain can convert textures to Terrain Layers, generate terrain from several models and split the model into several terrains.


Important: before starting, please make sure that your model has an Index Format - 16 bits. Otherwise, when the mesh has more than 65k vertices, Physic.Raycast is unstable and may cause the editor to freeze at any time.

Add your model that you want to convert into Terrain into the scene. The number of models is not limited, and they can have any nesting.

Important: Your model can be of any shape, but the resulting Unity Terrain will always be rectangular. Keep this in mind when converting non-rectangular models.

Select the menu item «Window / Infinity Code / Mesh to Terrain», to open Mesh to Terrain window. Or right-click on the object you want to convert in the Hierarchy window and select Convert Mesh To Terrain from the context menu.

Specify the required settings, click «Start» and wait for the conversion. Depending on your computer performance, the number of pieces and settings it can take from a few seconds to several minutes.

Important: If the model has a collider, other than «Mesh Collider», it can be converted incorrectly. To solve the problem, remove the collider component from models.

Description of fields



List of mesh, which will be converted into terrains, and general conversion settings.

Mesh select type - how you want to define a models for the conversion:

Direction - the direction of raytracing:

Y Range - desired range of heights:


Contains settings for created Terrains.


If «Type - New Terrains» is selected, then there are additional settings:


Mesh to Terrain can optionally generate one texture for each Terrains.

Result Type:

Mesh to Terrain has two modes for generating textures:

Auto Setup Lighting - automatically setup lighting in the scene for Capture Mode - Camera, and after conversion restores its original state.

Manual Light Setup for Capture Mode - Camera

There are many ways to setup the lighting in a scene.

The simplest and best result:

  1. Disable all lights in the scene.
  2. Open Window / Rendering / Lighting / Environment.
  3. Environment Lighting / Source - Color, Ambient Color - White.

After conversion, you can enable the lights, and return Environment Lighting / Source - Skybox.

Integration with third party assets

Third party assets are not included in Mesh to Terrain and must be purchased separately.

Huge Texture

Huge Texture allows you to generate textures up to 2GB (0.715 gigapixels, 26624x26624px for square textures without transparency).

Integration with Huge Texture is automatically enabled when importing Huge Texture into a project. Select «Mesh to Terrain / Textures / Result Type - Huge Texture», and specify the page size, number of columns and rows.

Huge Texture has several limitations:

  1. You cannot use Terrain Layers.
  2. You will be able to use only Texture / Capture Mode - Raycast (read more in the Description of fields / Textures section).
  3. Integration with Relief Terrain Pack will not work.

Relief Terrain Pack

Integration with Relief Terrain Pack is disabled by default.

Import Relief Terrain Pack to your project. Open Mesh to Terrain. Select Third-party / Enable Relief Terrain Pack.

No settings Relief Terrain Pack is required. If you have any questions about Relief Terrain Pack, you can find answers in the documentation of Relief Terrain Pack.

Important: Relief Terrain Pack is not compatible with Huge Texture, and you won't see the benefits of Relief Terrain Pack when generating Huge Texture.

If you want to remove Relief Terrain Pack from the project, you should first disable it in Mesh to Terrain (Third-party / Disable Relief Terrain Pack).

If you forget to disable Relief Terrain Pack and removed it, then you will see errors in the console. To manually remove support of Relief Terrain Pack, open Player Settings (Edit / Project Settings / Player) and remove the corresponding entry from «Scripting Define Symbols».

Updating versions

We send to Unity Asset Store only stable versions. Renewal period is several months.

Mesh to Terrain has a built-in update system, using which you can get early access to all versions and updates.

Click «Window / Infinity Code / Mesh to Terrain / Check Updates», to open window checking for updates. Enter your Invoice Number, select a channel of updates and click «Check New Versions».

If updates are available, you can read the list of changes and download the update.

If you have any problems with installing the update, then:

  1. Open an empty scene.
  2. Delete the folder «Infinity Code / Mesh to Terrain».
  3. Import the new asset version in the project.


After starting you get the error border or nothing happens.

There are two reasons for this:

  1. The models in the scene have a size that is insufficient for correct operation of physics. The problem is that the default scaling factor of imported models «0.01». You need to increase the model in 100 + times and start the component again.
  2. You choose the models are not in the scene. Add model in the scene and convert them.

Terrains not correspond to the models axis Y.

Scale up the model several times.

New terrains have a insufficient resolution / accuracy.

  1. Increase the Height Map Resolution.
  2. Increase the number of new terrains.

You cannot see the grass or trees.

  1. Zoom in to the place where you draw grass or trees.
  2. Increase the value of «Tree Distance» in Terrain settings.

You receive an error «Selected meshes not in the scene», and the model is in the scene.

Please make sure that you choose a model from the tab «Scene».

Conversion process freeze at some percentage

Please make sure your model has an Index Format of 16 bits. Otherwise, when the mesh has more than 65k vertices, Physic.Raycast is unstable and may cause the editor to freeze at any time.


We provide support by email ( in English and Russian languages, or using forum ( in English language.

If you have something does not work, you find a bug, or you have a suggestion, please contact us.

Huge Texture

Huge Texture

Huge Texture allows you to import and use textures larger than 8192x8192px.

How it works: When importing a texture, Huge Texture splits the texture into pages and saves it as a Texture Array. Texture Array is combined on the shader side, which does not create extra draw calls and has almost no effect on performance.
