Great War Trenches

Mud Floors, Log Structures, and Trench Foundations

The Great War Trenches package provides the essential architectural building blocks for constructing wet, muddy battlefield environments. The core of any trench network relies on reliable earthworks, and this collection supplies specific mud floors and mud walls to form the primary pathways. Accompanying these earthen boundaries are sturdy wooden log structures and wood board walls, giving developers the structural elements necessary to reinforce deep trench corridors and dugouts.

Wood board floor props prevent the scene from looking like an unnavigable mud pit, adding authentic, traversable detailing to the pathways. A collection of high-quality mud texture variations ensures that long stretches of the trench do not look repetitive, maintaining a grounded appearance suitable for World War I or similar historical battle settings. By combining the raw earth assets with the reinforced wooden supports, level designers can map out extensive, realistic defensive networks.

Prop Meshes and Collision Geometry

Beyond the foundational earth and wood, the collection includes 42 unique meshes designed to populate and clutter the defensive lines. Barbed wire serves as a critical perimeter defense prop, meant to be strung along the upper edges of the mud walls. Various sandbags offer modular cover options that can be stacked along the trench lips, corners, and firing steps. Wooden crates topped with canvas covers provide realistic supply caches that break up the visual profile of the trench floor.

The geometry of these assets is highly detailed, with vertex counts ranging from 100 on the simpler objects up to 200,000 on the most complex. Across the entire collection, the meshes average around 80,000 vertices. Every mesh utilizes custom and automatically generated collision, ensuring that characters and projectiles interact accurately with the dense, cluttered trench environment. Navigating around stacked sandbags or taking cover behind wooden crates relies heavily on this precise collision geometry.

Rain Systems and Tri-Planar Materials

To emphasize the wet and miserable conditions of a trench, the package features specialized weather and material systems built directly into the assets. A dedicated rain particle system is included, constructed specifically to be attached to the player character. This localized approach to weather rendering ensures that the downpour remains consistent around the camera viewpoint as the player moves through the sprawling trench network.

Complementing the particle rain is a tri-planar raindrop master material. This material setup allows raindrops to map accurately across the complex geometries of the mud and wood meshes without suffering from severe UV stretching. Tri-planar projection is particularly useful for terrain-like assets such as mud walls and organic log structures, ensuring that the wet surface details remain uniform regardless of how the meshes are rotated, scaled, or positioned within the level.

High-Resolution Textures and Unreal Engine 5 Integration

The visual fidelity of the trench environment is driven by a heavy reliance on high-resolution PBR textures and modern Unreal Engine 5 rendering features. The package contains 80 total textures, the vast majority of which are authored at high resolutions to support close-up inspection. Specifically, there are 38 textures at 2048x2048 and 36 textures at 4096x4096. A handful of smaller textures round out the collection, including three at 128x128, two at 512x512, and one at 1024x1024.

These textures feed into 4 Master Materials and 26 Material Instances, allowing for optimized material management across the scene. Intended for Unreal Engine 5.0 and above, the assets are fully Nanite-ready. Nanite handles the heavy vertex loads and automatic Level of Detail (LOD) scaling, making the 80,000-vertex average manageable in complex levels. The environment also supports Lumen, taking advantage of real-time global illumination and reflections. This dynamic lighting is crucial for accurately rendering the wet, muddy surfaces and integrating the included pre-made lantern Blueprint, which comes with its own attached light source. Development with these features is fully supported on both Windows and Mac platforms.

Adapting the Assets for Fantasy and Horror

While the primary design targets realistic war games and World War I battlefields, the raw materials of mud, wood, and rain lend themselves to alternative level design scenarios. The rugged wooden log structures and heavy mud walls are well-suited for fantasy environments, such as crude goblin camps set in deep forests or swamps.

The claustrophobic nature of a trench network, combined with the tri-planar raindrop materials and dynamic lantern lighting, provides an excellent foundation for horror mazes. The dense, enclosed pathways and atmospheric rain systems can be repurposed to create tense, low-visibility environments far removed from a traditional historical battlefield. By utilizing the modular wooden boards, mud variations, and dynamic lighting tools, developers can shape the collection to fit multiple genres requiring a damp, gritty aesthetic.
