Unreal Engine 5: Procedural Wall System

Master the design and implementation of a flexible, data-driven Procedural Wall System in Unreal Engine 5 using Blueprints, splines, mathematical concepts, and landscape-aware generation techniques.

This course goes beyond simply placing wall meshes along a spline. You’ll learn how to build a complete procedural wall generation system that automatically creates modular walls, fences, barriers, and similar structures while correctly handling segment placement, collisions, corner joins, terrain interaction, mesh stretching, and multiple wall configurations.

Throughout the course, you’ll progressively build the system from the ground up while also learning the mathematical concepts that make advanced procedural generation possible.

Your Learning Journey

• Spline-Based Procedural Generation - Learn how to generate static meshes along Unreal Engine splines and calculate the start and end positions of individual spline segments.

• Data-Driven Wall Configuration - Design a flexible system where wall properties can be controlled through structured data, allowing individual wall segments to override default settings when required.

• Wall Segment Generation - Build top, bottom, and repeated wall segments while controlling their placement, dimensions, and alignment along the spline.

• Prevent Mesh Stretching - Learn techniques for maintaining consistent wall proportions by dynamically placing modular meshes instead of excessively stretching them across spline segments.

• Spline Segment Collision - Generate and configure collision for procedural wall sections so that the generated structures can properly interact with gameplay systems.

• Vector and Trigonometry Fundamentals - Understand vectors, angles, radians, sine, cosine, tangent, and other mathematical concepts required for procedural geometry calculations.

• Dot and Cross Products - Learn how dot products and cross products are used to understand the relationship between spline directions, angles, orientation, and wall corners.

• Advanced Corner Joins - Understand the common corner-joining problem that occurs when procedural wall segments meet at different angles. Calculate corner offsets and determine accurate join positions to create cleaner connections.

• Staggered Wall Generation - Add variation to procedural structures by generating staggered wall arrangements suitable for brick-like or modular construction patterns.

• Landscape Deformation - Allow your procedural wall system to modify the landscape where necessary to produce more consistent structural placement.

• Landscape Conforming - Make generated wall sections follow terrain elevation and adapt naturally to uneven landscapes.

• Multiple Wall Types - Build a reusable system capable of supporting multiple wall styles and configurations without rewriting the core procedural generation logic.

• Debugging and Visualization - Display segment numbers and useful runtime information to better understand and debug procedural spline generation.

By the end of this course, you’ll have built a complete modular Procedural Wall System that can be adapted for walls, fences, fortifications, barriers, roadsides, architectural structures, and other spline-based environment systems.

More importantly, you’ll understand the theory behind the system instead of simply copying Blueprint nodes. Concepts such as vector direction, trigonometry, dot products, cross products, corner offsets, spline calculations, mesh dimensions, and terrain adjustment will give you a stronger foundation for building your own procedural tools in Unreal Engine.

The techniques covered in this course are directly applicable to environment generation, construction systems, city builders, strategy games, survival games, level-design tools, procedural architecture, and other projects that require dynamically generated modular structures.

Whether you are an intermediate Unreal Engine developer looking to improve your Blueprint and procedural-generation skills or a game developer building reusable environment tools, this course will give you a practical foundation for designing scalable procedural systems in Unreal Engine 5.
