Hi everyone,
New in this build of UniqueBuilder: IFC import from ArchiCAD.
I can now bring IFC files from ArchiCAD into Unreal, and the walls stay fully parametric and editable directly in-engine — nothing baked into static meshes on import:
Walls with start/end points, thickness, height
Openings that recalculate on the wall in real time
Full UV control directly in-engine
The goal is to keep the architectural data parametric all the way through, instead of importing everything as static geometry.
Any feedback or ideas are welcome.
Nice work! Keeping IFC data fully parametric inside Unreal instead of converting everything to static meshes is a very interesting approach. Real-time wall editing and opening updates could save a lot of time during design iterations. Looking forward to seeing how this evolves and performs on larger BIM projects.
At the moment I’m refactoring the whole system for Unreal Engine 6 and its right-handed coordinate system.
My goal isn’t to recreate the entire BIM workflow inside Unreal. I’m primarily focused on architectural visualization and converting BIM projects into interactive runtime experiences for clients.
Regarding large BIM projects, I don’t expect scalability to be a major issue. Unreal Engine is already highly optimized for handling large-scale environments.
I’m still deciding how much information should come from ArchiCAD. Right now I’m leaning towards using ArchiCAD mainly for 2D floor plans and essential BIM data, then generating and refining the architectural model directly inside Unreal using parametric tools.
For me, the bigger challenge isn’t rendering performance—it’s finding the right balance between importing BIM data and generating the architectural model directly inside Unreal while keeping the workflow simple and efficient.
I’d be interested to hear your thoughts. Do you think that’s a practical workflow, or would you prefer to keep more of the modeling inside the BIM application?
