01 / STREAM BIM TO RUNTIME
Stream BIM to runtime
Load your model directly into an Unreal experience with fast startup, strong performance, and no cloud dependency. Import the file into your scene and keep moving.
FRAGMENTSUNREAL::
Stream BIM into Unreal Engine
Keep your data
THE PRODUCT STATEMENT
BIM is more than geometry
FragmentsUnreal keeps the usable structure behind the model, so Unreal applications can inspect, understand, and work with the built world.
CAPABILITY TAKEOVER / SKELETON
From model to
application context
02 / WORK INSIDE THE EDITOR
Work inside the editor
Stream the model into the Unreal Editor for a controlled, deliberate workflow - ready for composition, lighting, and level authoring.
03 / MAKE THE MODEL YOURS
Make the model yours
Override materials, prepare the context around the model, and build a ready-to-ship level - or re-import at runtime with those same decisions intact.
04 / PLACE IT EXACTLY WHERE IT BELONGS
Place it exactly where it belongs
Choose the BIM project coordinates or the world origin, then offset the model into the exact position your experience needs.
05 / KEEP THE INFORMATION
Keep the information
The geometry is there. The data is still there. Now use both to build the application you actually want.
CORE CAPABILITIES
Technical control,
without the noise
Reusable primitives for applications that need both visual fidelity and data fidelity.

OPEN SOURCE / APACHE-2.0
AECO workflows should not be limited by closed formats, fragile handoffs, or the distance between a model and the people who use it.
FragmentsUnreal is built in the open to bring BIM into Unreal with the freedom to inspect, adapt, and build on top of the data. Lower the barriers. Raise the ambition. Change what the industry can make.
A clear path from
BIM to experience
ARCHITECTURE / PIPELINE
Keep the pipeline legible. Each layer can remain inspectable as the application grows.

DEVELOPER / API
Call the importer subsystem directly: load the Fragment asynchronously, then process the loaded model when it is ready.
// FragmentsImporterSubsystem / Blueprint-equivalent flow
UFragmentsImporterSubsystem* Importer =
GetGameInstance()->GetSubsystem<UFragmentsImporterSubsystem>();
FFragmentLoadOptions Options;
Options.OriginMode = EFragmentOriginMode::UseBaseCoordinates;
// Start the async load; the completion callback supplies ModelGuid and success.
Importer->LoadFragmentAsync(FragPath, Options, OnLoadComplete);
// Inside OnLoadComplete: process only when the load succeeded.
if (bSuccess)
{
Importer->ProcessLoadedFragment(
ModelGuid, OwnerActor, false, OnProcessComplete, nullptr);
}
else
{
UE_LOG(LogTemp, Error, TEXT("Fragment load failed: %s"), *ErrorMessage);
