Installation

Edit > Preferences > File Paths > Asset Libraries → + → choose the folder with tidebone_roof_pv.blend. Or File > Append → NodeTree → Tidebone Roof & PV.

Quick start

1. Add a plane and scale it to the house footprint, then add the Tidebone Roof & PV modifier. Empty mesh? Use Width / Depth.
2. Panels: General (form, ridge direction), Roof (pitch, overhangs, walls), Covering (tile type/colour, stagger, caps, detail, seed), Gutter and Downpipe, Dormers, Photovoltaics, L-Wing, Output (Realize), Materials.
3. Solar: tick PV Enable and choose the side. Read PV Module Count / PV Power kWp / PV Area / Tile Count from the group outputs or the pv_module_count attribute (Spreadsheet > Instances).
4. Real time: leave Realize off (tiles stay instances) and lower Detail. Export: turn Realize on, then apply the modifier.

Included

tidebone_roof_pv.blend (asset, helper groups, materials), asset catalog, render-ready demo scene, README, license (1 seat).
