LDraw Brick Model Generator is an Unreal Engine 5 editor plugin with two main workflows: open an existing .ldr LDraw model file, or convert a selected Static Mesh Actor in your level into a brick-style model.

LDraw Brick Model Generator UE 5.6‐5.8 User Guide

The plugin ships with 131 bundled LDraw Core part meshes, so files that use only those parts import immediately. If a file references additional designs, point the plugin at an LDraw complete.zip or another LDraw-compatible library in Project Settings; missing parts are converted and cached on demand, making later imports faster.

Mesh conversion is interactive: click Create Brick Model, adjust key settings in the Brick Generation Preview panel (Model Resolution, Part Family such as Brick/Plate/Tile, Use Source Colors, Fallback Color, Maximum Brick Length, Add Internal Supports), and generate when the translucent preview looks right. Results are saved as Blueprint Actors by default so they are easy to reuse, move between levels, and include in packaged projects.

Key highlights:

- Import .ldr and .mpd files with one click and reimport when the source file changes

- Convert any Static Mesh Actor into a brick-style model with a live translucent preview

- 131 bundled LDraw Core parts work out of the box; optional external LDraw libraries with on-demand part conversion and caching

- Part Family options (Brick, Plate, Tile), source-color support with fallback color, maximum brick length, and internal supports for floating layers

- Step playback controls on imported models: Next Step, Play Build Sequence, Show All Steps

- Blueprint auto-save with configurable output path and level actor replacement

- Advanced options available on demand: collision, materials, water optimization, animation presets, Sequencer controls, voxel thresholds, export paths, and result statistics
