The Shot: CG Cars and Live-Action Integration

In this project, I worked with live-action footage of my friend Nacho, integrating two CG cars (Audi & Porsche) into the scene. The main challenge? Achieving a seamless blend between the digital and real-world elements.

To help you recreate this shot, I’ve structured the process into a step-by-step breakdown, covering everything from shadow integration to color grading and optical effects.

The Compositing Workflow: A Step-by-Step Guide

To achieve a realistic VFX shot, I divided the process into three key stages:

Ground Preparation – Laying the foundation with realistic shadows.
Integration of CG Cars – Refining reflections, lighting, and color matching.
Final Enhancements – Rotoscoping, color correction, and optical effects.

Step 1: Ground Preparation – Setting the Foundation

A strong foundation is essential for a believable composite. Here’s how I ensured that the CG cars blended seamlessly into the real environment:

Hard Shadows

  • Extracted shadow passes from the CG render and adjusted diffusion for a natural look.

Blend Shadows

  • Combined soft & hard shadows to avoid harsh transitions between light and dark areas.

Soft Shadows & Ambient Occlusion

  • Added contact shadows where the cars touch the ground, reinforcing realistic interaction.

Wet Floor Effect

  • Simulated a reflective wet surface in Nuke to enhance realism and match the lighting mood.

Pro Tip: When working with CG shadows, always blur and blend edges to match the footage’s natural lighting conditions.

Step 3: Final Touches – Color Matching, Lighting, and Optical Effects

The last stage was fine-tuning the colors, lighting, and optical effects to make the CG elements feel truly integrated.

Color Correction & Grading

  • The raw CG render was too bright, so I toned down the highlights and matched the hues to the real-world environment.
  • Used Nuke’s grading tools to adjust contrast and midtones for a seamless look.

Lighting Adjustments

  • Enhanced ground bounce light to ensure the cars reflected the surrounding environment realistically.
  • Tweaked headlight glow for better interaction with ambient lighting.

Blur Matching for Depth Consistency

  • Ensured that the cars had the same motion blur & depth blur as the live-action footage.

Pro Tip: Always check your color balance across multiple shots to maintain consistency.

Rotoscoping & Optical Effects – The Final Polish

Rotoscoping for Seamless Integration

  • Cut out Nacho (the live-action character) so he appeared between the two cars convincingly.
  • Refined mattes and feathering to blend edges naturally.

Lens Flares & Optical Glows

  • Restored the lens flares interacting with the character to maintain scene continuity.
  • Used subtle highlights to enhance light interactions between CG and real footage.

Best Practice: When using optical effects, keep them subtle and natural—overdoing them can make your composite look fake.
