Installation

In Blender open Edit, Preferences, Get Extensions, then use Install from Disk (the arrow menu at the top right) and pick the tent_generator zip. Enable it if it is not enabled.

Making a tent

1. In the 3D Viewport press N to open the sidebar and select the Tent tab.
2. Pick a tent type and a design from the picture grids.
3. Click Place Tent: the tent follows the surface under the mouse, the mouse wheel turns it, Q and E change the design, and a click places it. Or use Add, Tent to put one at the 3D cursor.
4. Use the quick toggles (Doors Open, Guy Lines, Furnished, Lights On) and the panels below (Size & Ground, Structure, Fabric, Doors, Rigging, Interior, Look) to change anything. The tent rebuilds live.
5. In Detail & Output choose Low, Medium or High detail, and use Convert to Mesh to get a plain mesh for export to a game engine.
