Documentation – Garage Doors & Grass (Geometry Nodes)

The scene features two rigged, animatable garage doors and a simple Geometry Nodes grass setup.

• Doors are controller-driven (no pre-made keyframes).

• Grass is disabled by default and must be enabled per object in the Modifiers panel.

Garage Doors – Controllers

Controllers (red arrows):

• Driver Controller.small_Garage door → operates the small garage door.

• Driver Controller_big_Garage door → operates the big garage door.

How to use

1. Select the respective controller in the viewport or Outliner.

2. Move it along the arrow direction (G + drag) to open/close the door.

3. To animate, hover the changed value (e.g., Location) and press I to insert keyframes.

Notes

• Both doors are independent; animate each with its own controller.

• If a controller can’t be selected, ensure Object Mode and that the controller’s collection is visible/selectable.

Grass (Geometry Nodes)

Objects that hold the GN grass modifier:

• Surrounding soil

• Property

Enable per object

1. Select Surrounding soil and Property one after another.

2. In the Modifiers tab, toggle the Geometry Nodes modifier on (enable viewport/render as needed).

Performance tips

• Lower Density in the GN modifier if VRAM is tight.

• Consider camera-based culling/masks for shots where distant grass isn’t needed.

• Work in Solid/Material Preview; render final frames in Cycles.
