Runic Stone Hammer

Geometric Variations and LOD Structure

The Runic Stone Hammer is designed to support various performance requirements and visual styles through a series of 16 model variations. These variations are built upon a foundation of four distinct levels of detail (LOD): Low, Medium, High, and Ultra. The triangle counts across these levels span from a highly optimized 84 triangles at the lowest setting to 6148 triangles at the ultra-high setting. This range allows for the asset to be utilized in various scene contexts, from background environmental props to high-fidelity hero assets held by a character in close-up views.

Beyond the performance-based LODs, the developer has provided four specific geometry variants to alter the hammer’s silhouette and complexity. These include:

Normal: The complete model featuring all decorative elements.
No Spikes: A variation that removes the aggressive spiked elements from the hammer head.
No Ornament: A version that strips away the runic or decorative engravings for a more utilitarian look.
No Spikes & Ornament: A streamlined version of the hammer with both the spikes and the ornamental details removed.

Texture Mapping and Material Variants

The visual identity of the Runic Stone Hammer is defined by two primary texture variants: Stone and Dark Iron. These allow the hammer to transition between a primitive, monolithic appearance and a more refined, metallic aesthetic. To further customize the look of the weapon, the asset includes texture variants that allow for the removal of cracks on the sides of the hammer, providing a choice between a weathered, battle-worn appearance and a pristine finish.

The technical implementation of these textures utilizes a specific map structure designed for efficiency in the Unity engine. The asset package includes Albedo, Specular, and Normal maps with the following technical specifications:

Albedo Map: Provided at 1024×1024 resolution. This map includes Ambient Occlusion (AO) data baked directly into the Alpha channel, which helps define the depth and contact shadows of the runic engravings and hammer geometry without requiring a separate texture sampler.
Specular Map: Provided at 512×512 resolution. This map follows a Specular Color workflow and contains Gloss information within the Alpha channel to define the surface smoothness of the stone or metal.
Normal Map: Provided at 1024×1024 resolution to ensure the runic engravings and structural details are captured with high fidelity across the different LOD levels.

Implementation and Technical Details

Originally published for Unity version 5.3.4, the Runic Stone Hammer is packaged as a unitypackage file with a total size of 10.0 MB. The package is comprised of 54 individual assets, which include the various mesh LODs, texture maps, and material configurations required to deploy the 16 hammer variations.

Because the asset includes pre-configured LODs and multiple mesh variants, it supports a workflow where the developer can swap out the hammer’s appearance based on gameplay needs—such as weapon upgrades or different enemy tiers—while maintaining a consistent runic theme. The inclusion of the “No Spikes” and “No Ornament” meshes provides additional flexibility for developers who need to differentiate between several instances of the same weapon type within a single project.

The use of a 1024×1024 resolution for the primary maps ensures that the realistic, nordic-inspired details remain sharp even when the hammer is the focus of the player’s view. Meanwhile, the lower resolution of the specular map (512×512) and the integration of AO and Gloss into alpha channels demonstrate a focus on balancing visual quality with texture memory usage.
