Working with the Tool

For projects where blocky, low-poly, and stylized aesthetics are central, game developers and artists working within Epic Games' engine now have access to a dedicated voxel plugin named Voxy. This tool is engineered to create immersive game worlds by combining voxel-based modeling capabilities with Unreal Engine’s rendering ecosystem. It allows users to build natural environments and characters and aims to deliver high speed and low resource consumption.

At the core of organizing work are two concepts: individual volumes called VoxyAsset, and collection containers called VoxyBundle. Users can create as many individual volumes as needed and assemble them into a bundle. This system allows for managing large or complex scenes by breaking them into manageable parts without being limited by a single volume container.

Setting Up for Voxy in Unreal Engine

Before diving into content creation, the project environment must be correctly configured. The tool requires the project settings to be set to DirectX 12, and Shader Model 6 (SM6) must be enabled. This ensures compatibility with modern rendering pathways and allows the plugin to communicate effectively with the engine’s advanced graphics systems.

Creating and Editing Voxel Assets

Building content within the plugin relies on various editing functions and brush types. Users have access to tools such as:

  • Brush: For freehand painting and placement of voxel data.
  • Line: For creating straight, structured strokes between points.
  • Region: For filling or affecting larger defined areas.
  • Extrude: For pulling 2D voxel surfaces into 3D forms.
  • Bevel: For creating angled or rounded edges on blocky structures.
  • Smooth: For refining rough surfaces and blending voxel transitions.
  • Clone: For duplicating existing geometry to quickly repeat details.

These procedural editing functions are also exposed to Blueprint systems, allowing developers to script changes and interact with voxel data programmatically rather than only through manual modeling sessions.
