- Unreal developers working with IFC building models
- Worth noticing
- Its three LOD tiers shift from individual elements nearby to merged cells and a proxy at a distance.
Field notes
The described pipeline starts with an IFC model converted to a .frag file, which can then be loaded through Blueprint or C++. The site says nearby geometry remains individually selectable while more distant buildings use merged cells or a proxy, and that IFC properties remain available for filtering and inspection. Its campus example pairs IFC-derived buildings with point clouds and photogrammetry in one scene.
