Blender Isometric Car Renderer

This script automates the process of rendering an isometric car model in Blender from multiple angles and compiles the resulting images into a spritesheet. The script ensures correct lighting, camera positioning, rendering settings, and image processing using Blender’s Python API and Pillow for image manipulation.

Camera and Light Setup

• Ensures an orthographic camera is present; otherwise, creates one.
• Configures an isometric perspective with predefined angles.
• Adds a SUN light source named "Iso_Light" if not found.
• Positions the light to create soft shadows.

---

Car Model Setup

• Searches for an object named "car-model".
• Moves the camera to a fixed isometric position.
• Ensures all constraints on the car are muted for rotation control.

---

Rendering Settings

• Output format: PNG (with transparency).
• Image resolution: 80x80 pixels per sprite.
• Anti-aliasing: Disabled for sharp pixel rendering.
• Frame count: 60 (adjustable for smoother rotation).
• Rendering engine: Eevee (optimized for speed).

---

Rendering Process

1. Loops through 60 angles, rotating the car around its Z-axis.
2. Clears animation data and applies new rotation values.
3. Renders each frame and saves it as a PNG file.

---

Spritesheet Generation

• Uses the Pillow library to combine all rendered images.
• Arranges images in one row, each offset horizontally.
• Saves the final spritesheet as "spritesheet.png" in the output folder.

---

Output Directory

• The script automatically creates a //sprites folder inside the Blender project directory.
• Individual frames are saved as car_00.png, car_01.png, … car_59.png.
• The final spritesheet is named "spritesheet.png".

Example Usage

Running the Script in Blender

1. Open Blender.
2. Switch to the Scripting tab.
3. Create a new script, paste the code, and run it.
