Installation

In Blender open Edit, Preferences, Get Extensions, then use Install from Disk and pick the indian_bus_generator zip.

Usage

1. Open the Bus tab in the 3D viewport sidebar (N). With nothing selected, click the picture to pick one of the 13 buses, then press Add. You can also use Shift+A, Mesh, Indian Bus.
2. The card at the top shows the bus. Click its picture to switch to another preset. Surprise Me makes a random bus, Variation changes the current one and New Seed reshuffles the dents, luggage and small details.
3. Click the Body and Front pictures to change the bus, and drag Length, Width and Height.
4. The Condition picture sets every wear slider at once (New, Used, Old & Dirty, Rusty Wreck). Dents, Rust, Dirt and Broken Glass are right next to it.
5. Pick a roof carrier, then the Roof Load picture, its amount, the tarp and the bicycles.
6. Livery, colors, the destination board script and the window style are in the next box. Doors, wear details, small details, motion and export wait in the closed sections below.
7. In Motion & Lights, click Pose Rig to animate Root, Suspension, Steering, Wheels and individual Wheel Bump controls. Rotate the door controls to open the driver door and folding passenger leaves. Bake Wheels keys rotation from the animated travel over the scene frame range. Drive and Steer sliders are also animatable.
8. For game engines set Detail to Low and use Convert to Mesh; the meshes have UVs, the origin on the ground under the middle of the bus and Principled BSDF materials.
