Level Design: Mastering Blocking Volumes for Compelling Game Spaces

The siren song of hyper-detailed assets can be deafening, especially when starting level design. Resist! Before sculpting mountains or meticulously crafting cobblestone streets, embrace the humble blocking volume. They are the unsung heroes of level design, and learning to wield them effectively is the fastest path to creating compelling game spaces.

What are Blocking Volumes?

Blocking volumes are simple, often untextured, 3D shapes used to represent level geometry in its early stages. Think of them as digital LEGO bricks for level designers. They define the boundaries of the playable space, dictate player movement, and establish the initial layout and flow of a level. More than just placeholders, they are active design tools.

Sculpting Space: Creating Basic Shapes

Start with the primitives. Cubes, cylinders, spheres – your engine’s basic shapes are your best friends. Don’t get bogged down in detail. The goal is rapid prototyping.

For example, create a long, thin cube to represent a corridor. A larger cube becomes a room. A vertical cylinder could be the base of a tower.

Actionable Insight: Use a consistent grid size for your blockout. This makes it easier to maintain proportions and snap objects together accurately, leading to cleaner level architecture. A grid size of 100 units is a good starting point in Unreal Engine.

Defining Playable Space and Guiding Player Flow

Blocking volumes aren’t just about creating static shapes; they’re about defining what the player can interact with and how they interact with it.

Use them to create pathways, obstacles, and areas of interest. Consider how the player will navigate the space.

For instance, a series of strategically placed blocking volumes can funnel players toward a specific objective, creating a sense of direction. Conversely, open areas can encourage exploration.

Common Pitfall: Creating corridors that are too narrow. This feels claustrophobic and limits player movement. Err on the side of wider corridors during the blockout phase. You can always narrow them later during detailing. Aim for at least 300 units width if you are using Unreal Engine.

Iterating on Blockouts: Refining Gameplay and Visual Interest

This is where the magic happens. Playtest your blockout! This is crucial. Move the player character through the space and see how it feels. Is it fun? Is it challenging? Are there any areas that are confusing or frustrating?

Don’t be afraid to tear down and rebuild. Blocking volumes are quick to create and modify, so experiment freely.

Case Study: Many games use colored blocking volumes to represent different gameplay elements. Red could indicate enemy spawn points, blue could represent pickups, and green could signify interactive objects. This color-coding helps designers quickly visualize the level’s gameplay without needing detailed assets.

Specific Challenge: Getting the scale right. It’s easy to misjudge the size of objects in 3D space. Use the player character as a reference. Ensure doorways are tall enough, platforms are wide enough to stand on, and cover is adequately sized. Iteration and constant playtesting are key to solving this. A simple trick is to make a rudimentary player model to easily compare.

From Blocks to Beauty: Preparing for Detailing

Once you are happy with the overall layout and gameplay of your blockout, you can begin the process of detailing. This involves replacing the blocking volumes with more detailed assets, adding textures, lighting, and special effects.

The blockout serves as a blueprint for this process, ensuring that the final level retains the core design principles established in the early stages.

Actionable Insight: Don’t delete your blockout! Hide it or move it to a separate layer. It can be invaluable for reference during detailing, ensuring that you maintain the correct proportions and spacing. It also allows you to quickly revert to the original blockout if you need to make significant changes.

Avoiding Design Paralysis: The Power of Limitation

One of the biggest advantages of using blocking volumes is that they force you to focus on the fundamentals of level design: layout, flow, and gameplay. The lack of visual detail encourages you to think critically about the player experience and prevents you from getting bogged down in aesthetic considerations too early in the process.

Original Insight: Think of blocking volumes as the “wireframe” of your level. Just as a wireframe outlines the basic structure of a website before the visual design is added, blocking volumes define the core elements of your level before you start adding details. Embrace the limitations and use them to your advantage.

Conclusion: The Foundation of Great Levels

Mastering the art of blocking volumes is not about creating visually stunning environments; it’s about creating engaging and enjoyable gameplay experiences. By using these simple shapes effectively, you can lay the foundation for truly great levels that will captivate and challenge players. So, ditch the fancy assets for now, embrace the block, and start building!
