The main goal of this Asset was it to be able to create the foundation for an Open-World/Sandbox map
with only one click. The generated Terrain chunks are Unity Terrains making it easy for level designers to make changes to them.
Example Result without changes:
1. Scripts
1.1 GenerateTerrain + GenerateTerrainEditor:
These two scripts are the main logic of this Asset.
While "GenerateTerrain" handels everything related to map generation,
the "GenerateTerrainEditor" class draws a custom inspector for the "GenerateTerrain" class
to make it able to call the Generate method form the inspector while in Edit mode.
1.1.1 The Inspector:
In the Inspector there will be a lot of options you can customize and it can
be a bit overwhelming at first so we will go over each option step by step.
The dimensions of the generated Sandbox
height cap for mountains on the Terrain
Details are Bumps in the Terrain. Large, Big, Medium and
Small Details will be overlayed/added.
Height controls the strength of these Bumps and Noise Scale
controls the frequency. A lower frequency will result in
wider bumps and a high frequency will produce dens/sharper
bumps.
lets you tweak the final bumps by subtracting an amount
from the final results of the bumps before added together.
A negative value will add to the result.
lets you multiply the result. For sharper Bumps x>1
and x<1 to smooth it out.
Raise the result to the power of this option.
Material used for all Terrain chunks (used for custom Shader)
Terrain Textures: see below!
Vegetation Textures: see below!
Grass Density:
the higher this value the more grass there will be placed.
tint used for healthy grass.
tint used for dry grass.
Building Objects Section: see below!
Wall to close the map Section: see below!
Random Offset Seed:
Set the Seed for Unitys Random.
Set the Material for the Map restriction wall/border.
Set the height of the map restriction wall/border.
Save this to save all numerical values you set.
The button below makes copying easy.
Will start generating the Sandbox. Might take some time
depending on the size of the Sandbox/Terrain.
You can press the button "Paste Seed from Clipboard"
to paste a seed you have saved and the click on
"Recreate from Seed" to restore all numerical values from
the seed and generate a Sandbox based on these settings.
1.1.1.1 Terrain Textures:
Under Terrain Textures you can assign up to 16 Textures that will be used on the Terrain.
The Type of Texture will change by what opacity of the Texture will be Influenced:
Opacity controlled by the "Height Curve"
horizontal is Terrain height from 0%-100% (0-1)
vertical is opacity from 0%-100% (0-1)
Opacity controlled by the "Angle Curve"
horizontal is Terrain slope from 0°-90° (0-1)
vertical is opacity from 0%-100% (0-1)
Controlled by value from Height Curve * value from Angle Curve.
Texture opacity is 1 where buildings are placed
and 0 everywhere else.
Opacity is 1 on the Sandbox border area
and 0 everywhere else.
Opacity based by the normal direction.
You can select the direction under "Normal"
Controlled by "Normal Curve".
horizontal is Terrain angle to the selected direction
from 0°-90°
vertical is opacity from 0%-100% (0-1)
1.1.1.2 Vegetation Textures:
Here you can assign grass textures to be used in terrain settings:
1.1.1.3 Building Objects & Map Border Wall (Wall to close the Map):
1.2 TerrainTexture:
Is just a class without methods so we can use Objects of type TerrainTexture in our
GenerateTerrain class.
2. Models
2.1 Border
2.1.1 Tower:
Simple Tower Object with albedo and normal both 4k
2.1.2 Wall:
Simple Wall Object as Map Border with 3 different 4k Texture sets for variation.
Each Texture set has albedo and normal.
2.2 Buildings:
All Buildings listed here have an albedo and normal map each 4k and 2 LOD models with a diffuse
map.
2.2.1 Container:
2.2.1.1 Container1 (completely open)
2.2.1.2 Container2 (one side closed)
2.2.1.3 ContainerClosed (completely closed)
2.2.2 Metal
2.2.3 Shed
2.3 Objects:
All Objects listed here have an albedo and normal map each 4k and 2 LOD models with a diffuse
map.
2.3.1 Barrel:
The Barrel also comes with a metalness map
2.3.2 Boulder
2.3.3 Rock
2.3.4 Stone
3. Prefabs:
3.1 Model Prefabs:
All Objects and Buildings are set up as prefabs with Materials, LODs, Colliders and Tags set up.
3.2 Trees:
Some simple trees made with Unitys tree Creation Tool (using textures in this package)
3.3 Sandbox Preset:
Prefab of an example Sandbox with everything set up already
(ready for drag and drop into your scene)
4. Scenes:
4.1 Small Example Scene
5. Shader:
5.1 HoloWall:
The HoloWall shader is a simple animated unlit shader for the map border.
5.2 XenoTerrain:
The XenoTerrain shader is a custom Terrain shader. (XenoTerrainAddPass will be used
automaticly when needed).
It has the following features:
distance blending to minimize tiling
noise overlay to minimize tiling
triplanar mapping for less distortion on steep areas of the terrain
hard blending between textures
6. Skybox:
Simple procedural Skybox for the Example Scene
7. Textures:
7.1 Ground Textures:
18 4k Ground Textures with Normal map
7.2 Vegetation Textures:
7.2.1 Grass Textures
7 custom grass Textures
7.2.2 Textures for Tree Creator:
-3 Bark textures with normal
-7 Leaf textures with normal
Thanks for the read and sry this looks ugly i markdown isnt the best for this.
