Hi everyone!
I’m an archviz artist at an architecture firm, and I’ve been building the toolkit I always wanted inside Unreal. It’s called Harmonia. One lighting rig and twelve viewport tools for UE 5.7 and 5.8, built around the Path Tracer.
The lighting rig
- HDRI and sun/sky modes, with independent control of backdrop intensity, colour and saturation
- No more matching the HDRI and directional light angles to avoid double shadows — rotate either freely
- Lighting presets, plus a sun position calculator for real-world sun studies
- Every control can be keyed straight into Sequencer
The tools
- Scatter system: mesh, spline and brush scattering that survives moving between levels, mesh reimports and rescales — no performance cost, and far lighter to set up than PCG
- Parametric floor generator: herringbone, chevron, basket weave and more
- White override for clay renders that restores exactly, even after closing the project
- Path-traced screenshot tool with denoiser handling
- Asset library with drag-and-drop placement, guides, compass menu and more

It’s an engine-level plugin. I’ll keep this thread updated with new tutorial episodes and releases. Happy to answer questions, and I’d genuinely love feedback from anyone using it in production.
