Creating atmospheric effects such as fog in 3D rendering can turn a standard scene into a captivating visual experience. In this article, we will explore how to achieve a Blade Runner-inspired fog effect using Redshift’s volume scattering capabilities in Cinema 4D. This technique is not only visually striking but also relatively simple to implement, allowing you to enhance your projects with professional-grade aesthetics.

Understanding Volume Scattering in Redshift

Volume scattering in Redshift is designed to simulate haze or volumetric fog in a scene. Unlike localized effects, volume scattering interacts throughout the entire environment, which provides a realistic depth to your renders. Here’s how you can set it up:

Setting Up the Scene

1. Create a Redshift Environment:

• In Cinema 4D, navigate to the Redshift tab.
• Locate the Objects menu and select Redshift Environment. This will create a global atmosphere for your scene, enabling the volume scattering effect.

1. Adjust Lighting:

• Select the lights that you want to contribute to the volume.
• Go to the Volume tab and set the Contribution Scale to 1. If the light source is too bright, it may overexpose the fog effect, so it’s essential to balance this setting.

Customizing Your Volume Scattering

Now that you have your environment and lighting set up, it’s time to customize the properties of your volume scattering to achieve the desired aesthetic. Below are key parameters you can tweak:

Scattering Amount

• The Scattering Amount parameter directly controls how much fog you will see in the scene.
• For a strong fog effect reminiscent of Blade Runner, a setting around 0.1 is often appropriate, ensuring the fog remains visible without overwhelming the scene’s overall brightness.

Attenuation

• Attenuation describes how much light gets absorbed as it travels through the fog. This parameter can help create a sense of depth, making the fog denser near the light sources and lighter as it moves away.
• A typical value to start with could be between 0.15 and 0.2, allowing for a more nuanced gradient from bright to darker areas of the fog.

Phase Control

• The Phase setting determines the appearance of your fog. A positive phase value biases the scattering effect toward the camera, creating a veil like appearance, while a negative phase value disperses the effect further away from the camera.
• Experimenting with phase values can yield various results—from softer fog edges to stark, defined silhouettes. For a classic cinematic look, you might maintain the phase setting at 0.

Practical Tips for Achieving the Blade Runner Aesthetic

• Color Choices: Using a yellow light in combination with an orange volumetric color will help emulate the iconic look of Blade Runner scenes. This clash of warm and cooler tones helps create a more dramatic atmosphere.
• Lighting Techniques: Higher contrast in your lighting setups can enhance the feel of depth and drama in your fog. Playing with shadows and light placement will yield better results.

Non-Light Dependent Fog

• Redshift offers options for non-light dependent fog found within the Fog section. This can be advantageous for certain scenes where you might want fog effects that do not directly rely on specific light sources.

Conclusion

The ability to create stunning fog and atmosphere in your renders can significantly enhance the narrative and emotional expression of your work. The techniques discussed here will not only help you achieve visually appealing results but also give your projects a professional touch. By experimenting with these parameters in Redshift’s volume scattering settings, you can breathe life into your scenes, capturing the essence of cinematic masterpieces like Blade Runner.
