One Landscape Material to RULE THEM ALL - Unreal Engine Tutorial #ue5

Introduction

In this tutorial, you will learn how to create a versatile landscape material in Unreal Engine 5 that serves as a solid foundation for all your landscape projects. This material allows for easy customization and includes features such as displacement and the ability to eliminate grid lines for a more natural appearance.

Step 1: Set Up Your Project

• Open the Unreal Engine and press Control + Space to access the Content Browser.
• Create a new folder for your landscape materials to stay organized.
• Download the following materials using the Quixel Bridge:
  • Western Ground Gravel Slate 01
  • Icelandic Rocky Ground
  • Soil Ground

Step 2: Create the Landscape Material

• Right-click in the folder you created and select Material, naming it mmore_landscape_R2.
• Open the material editor by double-clicking the material.

Step 3: Import Textures

• In the material editor, press Control + Space and navigate to Mega scans > Surfaces.
• Drag and drop your downloaded textures into the material editor.

Step 4: Set Up Material Attributes

• Create a Break Material Attributes node.
• Add a Landscape Layer Blend node. Set it to use three layers for now.
• Connect the output of the Break Material Attributes to the Landscape Layer Blend.

Step 5: Create Color Control

• Add a Make Material Attributes node.
• Use a Desaturation node to adjust the texture colors.
• Connect nodes as follows:
  • Create a Constant Vector for RGB control.
  • Use a Multiply node to combine color values.
  • Create parameters for Base Color Tint and Base Color Control.

Step 6: Configure Normals and Roughness

• Set up the normal map:

  • Create a Parameter node for the normal map.
  • Connect it to a Flatten Normal node.

• For roughness:

  • Use a Power node, followed by a Multiply node for roughness control.
  • Create parameters named Base Rough Contrast and Base Rough Intensity.

Step 7: Set Up Ambient Occlusion and Displacement

• Connect ambient occlusion, roughness, and displacement maps:

  • Use a Power node for roughness.
  • Connect the correct channels to ensure proper functionality.

• For displacement, connect directly to the displacement input, enabling it in the material properties.

Step 8: Eliminate Grid Lines

• To remove grid lines, add a Texture Coordinate node.
• Create parameters for tiling and variation:
  • Connect the nodes accordingly and adjust settings to achieve a natural look.

Step 9: Duplicate and Organize

• Copy and paste the material setup to create variations.
• Rename parameters for better organization, such as changing the mid-layer names to Mid Layer.

Step 10: Apply the Material Instance

• Save the material and create a material instance.
• Assign the material instance to your landscape in the level editor.
• Adjust the landscape layers using the Weighted Layer Blend to define different materials across your landscape.

Conclusion

You have now created a comprehensive landscape material in Unreal Engine 5 that can be easily modified and reused in future projects. Play around with the parameters and textures to achieve the desired look for your landscapes. For further enhancements, consider exploring additional texture variations and blending techniques to refine your landscapes even more. Happy developing!
