FragmentsUnreal 1.0.0

The first open-source release of FragmentsUnreal: stream That Open Fragments (.frag) BIM models into Unreal Engine and keep every floor, category and property.

Precompiled downloads (Win64)

Each zip holds the plugin built for one engine version: editor binaries, plus the precompiled runtime for packaged games (Development and Shipping). Blueprint-only projects can use it without building C++.

Engine	Download
UE 5.4	FragmentsUnreal-1.0.0-UE5.4-Win64.zip
UE 5.5	FragmentsUnreal-1.0.0-UE5.5-Win64.zip
UE 5.6	FragmentsUnreal-1.0.0-UE5.6-Win64.zip
UE 5.7	FragmentsUnreal-1.0.0-UE5.7-Win64.zip
UE 5.8	FragmentsUnreal-1.0.0-UE5.8-Win64.zip

Install: unzip into [YourProject]/Plugins/ so the path is Plugins/FragmentsUnreal/FragmentsUnreal.uplugin, open the project, and enable FragmentsUnreal in Edit > Plugins. Pick the zip that matches your engine version: a build for one version won't load in another.

SHA256SUMS.txt lists the checksum of each zip. To build from source instead, follow the getting started guide.

What's in 1.0.0

• Fragments .frag import for OpenBIM/IFC workflows, at runtime and in the editor.
• Asynchronous, chunked, shell-first streaming with continuous view-driven LOD: each model moves between its LOD2 proxy, LOD1 merged cells and LOD0 instances by screen-space error.
• Metadata queries, selection, floor and category visibility, and diagnostics, all exposed to Blueprint.
• Editor streaming through the same LOD path as runtime, with undo/redo for material and placement edits and live placement fields in the Fragments panel.
• Builds without a shared precompiled header, so Blueprint-only projects can package a game with the plugin (#7).

The full list, including the removed pre-release activation API, is in CHANGELOG.md.
