GAME ART GUIDE - BLOCKING OUT

INTRODUCTION

The blockout stage is the foundation of 3D environment and prop art pipelines for games. It converts 2D concepts or abstract design ideas into a simple 3D structural mesh before committing time to high-poly modeling, UV unwrapping, or texturing.

THE ROLE OF REFERENCE IN BLOCKOUT

Reference gathering serves as the objective anchor for the entire blockout phase, eliminating visual guesswork.

• Proportion and Architectural Accuracy - Real-world references reveal standard dimensions (door heights, stair increments, window sills) that prevent assets from looking unnatural.

• Silhouette Analysis - Breaking reference images into simple geometric breakdowns helps identify what primary silhouettes define the asset or scene.

• Functional Context - Reference dictates how components fit together mechanically or structural-wise (e.g., how support beams connect to a wall, or how a scope mounts to a rifle).

CORE STAGES OF BLOCKOUT

• Scale Calibration - Scale Rig/Human Reference: Before placing a single primitive, import a standardized scale mannequin (typically 1.8 meters / 180cm tall) into the scene.

• Engine Parity - Ensure the 3D software units match the target game engine (e.g., 1 Unit = 1 Centimeter for Unreal Engine).

• Shape Definition & Silhouette - Primary Shapes: Model the macro form using basic primitives (cubes, cylinders, spheres). Focus strictly on overall volume, balance, and readable silhouettes from gameplay camera angles.

• Secondary Breakdown - Cut into primary shapes to define major angles, bevels, or structural breaks, without adding localized geometry or bevel details yet.

• No Micro-Detailing - Avoid subdivisions, bevels, or complex topology at this stage to keep adjustments fast and non-destructive.

CONCLUSION

The blockout stages is vital in establishing the base shapes and forms associated with a given prop or environment. It is a vital first step in the creation of high quality art for video games.
