In Unity, you can quickly create a terrain by using a script. This can be done by using the Terrain object’s SetTerrainData function. This function takes a TerrainData object as its parameter. The TerrainData object contains all the information about the terrain, including the heightmap and the texture data.
To create a TerrainData object, you can use the TerrainData.CreateTerrainData function. This function takes two parameters: the width and the height of the terrain. The width and height of the terrain must be a power of two. For example, you can create a TerrainData object with a width of 1024 and a height of 1024.
Once you have created the TerrainData object, you can set the heightmap by using the TerrainData.SetHeights function. This function takes an array of floats as its parameter. The array represents the height of the terrain at each point. The first element in the array is the height of the terrain at the top-left corner, and the last element is the height of the terrain at the bottom-right corner.
After you have set the heightmap, you can set the texture data by using the TerrainData.SetTextures function. This function takes an array of Texture2Ds as its parameter. The array represents the texture of the terrain at each point. The first element in the array is the texture of the terrain at the top-left corner, and the last element is the texture of the terrain at the bottom-right corner.
Once you have set the heightmap and the texture data, you can create the terrain by using the Terrain.CreateTerrainGameObject function. This function takes the TerrainData object as its parameter. This will create a GameObject with a Terrain component attached to it. The Terrain component will have the heightmap and texture data that you set earlier.
Now that you have created the terrain, you can add trees, detail objects, and grass by using the Terrain.AddTreeInstance and Terrain.AddDetailInstance functions. These functions take a TreeInstance and a DetailInstance as their parameters, respectively.
The TreeInstance contains information about a tree that will be placed on the terrain. The DetailInstance contains information about a detail object that will be placed on the terrain.
You can also add a script to the Terrain game object. This script can be used to automate the process of creating the terrain. For example, you can use the script to set the heightmap and the texture data automatically.
In this way, you can quickly create a terrain in Unity by using a script.

How do you auto generate terrain in Unity?
There are a number of ways to generate terrain in Unity, but the most common and straightforward method is to use Unity’s built-in terrain engine. To do this, simply create a new terrain object in the Unity editor, and then use the terrain tools to sculpt and paint the terrain as you desire. Once you are satisfied with your terrain, you can then export it as a Unity terrain asset, which can be used in your game or application.
How do you make a 2D randomly generated terrain in Unity?
There are a number of ways to generate a 2D terrain in Unity. One way would be to use a noise function like Perlin or Simplex noise to generate a height map, then use that height map to generate a mesh for the terrain. Another way would be to use a Voronoi diagram to generate the height map, then use that to generate the mesh.
Is it better to make terrain in Unity or blender?
There is no definitive answer to this question as it depends on personal preference and what you are looking for in terms of results. If you are looking for a more realistic terrain, then Unity might be a better option. However, if you are looking for a more stylized terrain, then Blender might be a better option.
How do I get infinite terrain in Unity?
There is no definitive answer to this question as it depends on what you mean by “infinite terrain”. However, some possible methods to create large or infinite terrains in Unity include using multiple terrains which are stitched together, or using procedural generation to generate new terrain as the player moves.
