Overview of Kit Structure in Unreal Engine

With the latest update, KitBash3D kits now follow a new organizational structure within Unreal Engine's Content Browser. You'll notice expanded folders and improved asset management designed to simplify your experience.

New Folder Structure Includes:

Blueprints (Primary building blocks for scenes)
Levels
Materials / Master Materials
Static Meshes
Textures

This replaces the previous structure, which featured only "Actors" and "Geometries" alongside materials.

The introduction of packed level actors and Blueprints creates a stronger foundation for building your scenes.

Start With Blueprints

To begin constructing your environment, navigate to the Blueprints folder rather than "Actors" or "Geometries." Inside, you’ll find:

Buildings – Complete modular structures (e.g., 30+ in the Cyberpunk kit)
Props – Additional details and smaller assets used within or around buildings

For vehicle kits, this folder will be categorized as Vehicles and Props instead.

These assets are drag-and-drop ready, making world-building fast and intuitive.

Improved Texture Performance

To optimize performance, all 4K kits now default to 2K resolution using a texture LOD bias of 1. This ensures better runtime performance out of the box, especially for larger scenes.

Customizing Texture Quality:

If you're aiming for higher detail in specific areas (e.g., foreground shots):

Select the desired textures.
Go to Edit > LOD Bias and change the value to 0 to restore full 4K resolution.

This allows creative control over visual fidelity and performance.

Modular, Blueprint-Based Buildings

Buildings are no longer single, uneditable static meshes. Each structure is now a Blueprint made up of multiple modular assets. These changes provide:

Improved editing: Right-click any building, go to Level > Edit, and easily modify its internal components directly within Unreal Engine.

Full collision support: Instantly drop in a character and begin testing or gameplay.

Proper pivot points: Every piece is now aligned with logical, consistent pivots for easier manipulation.

These enhancements drastically reduce the time needed to make changes and eliminate the need to export and re-import modified meshes.

Enhanced Material Workflow & Nanite Compatibility

We’ve also made key material changes to support better visuals and performance:

Translucent and glass materials are now separated, giving you greater control and clarity.

Nanite support is fully integrated, providing higher fidelity and better performance out of the box.

These updates contribute to a smoother and more optimized experience when working with KitBash3D assets in real-time environments.
