Lighting Basics

In this lesson, we move into basic lighting setup in Cinema 4D, focusing on how to quickly create clean, professional-looking results without getting overwhelmed by complex lighting theory.

We begin by grounding the scene with a studio-style infinity wall (cyclorama) instead of a simple plane. A curved backdrop eliminates harsh horizon lines and unwanted background shadows, helping keep the viewer’s attention on the hero objects while also improving light bounce for subtle fill and rim lighting. Using a Studio preset from the Asset Browser, we adjust the width, curvature, and vertical position to ensure it fills the camera view cleanly without intersecting other geometry.

Next, we open the Redshift RenderView to evaluate the lighting. This immediately highlights how unflattering the default camera light is, which leads into a discussion of common lighting approaches. While traditional three-point lighting using area lights is introduced conceptually, the lesson emphasizes a faster and more beginner-friendly alternative: image-based lighting (IBL).

To achieve this, we add a Redshift Dome Light, which surrounds the scene with light based on an image rather than manually placed lights. On its own the dome light is flat, but once we load an HDRI map from the Asset Browser, the scene is instantly lit using real-world lighting captured in that image. This provides natural shadows, realistic reflections, and a cohesive overall look in seconds.

You’ll learn how to:

• Swap between different HDRI environments (outdoor vs studio)

• Adjust exposure/intensity to control brightness

• Rotate the lighting using Rotate on Horizon to change shadow direction

• Tweak saturation to reduce or enhance color casts

• Use coordinate rotation when finer control is needed

The lesson also explains how to identify which HDRIs are free versus Maxon One–exclusive, and notes that you can download additional HDRI maps online, provided they are .hdr or .exr files.

Finally, we load the exact HDRI used for the final render (included via link in the project files) and fine-tune its exposure and rotation. The lesson wraps by positioning HDRI lighting as an ideal starting point: fast for look development, flexible for iteration, and easily complemented later with additional lights for polish or drama.

Workflow tips covered in this lesson:

• Use a curved studio backdrop to avoid distracting background shadows

• Adjust backdrop size and curvature in camera view for clean framing

• Dock the Redshift RenderView for a more efficient layout

• Disable RenderView status text if it becomes distracting

• Start lighting with an HDRI for fast, realistic results

• Rotate HDRIs instead of moving lights to control shadow direction

• Lower saturation if an HDRI introduces unwanted color casts

• Use HDRIs as a base, then layer additional lights if needed

Shortcut & UI Tips Recap

• Dock panels – Customize your workspace for lighting workflows

• Asset Browser search – Quickly find studio presets and HDRIs

• Drag HDRI into Dome Light Path slot – Automatically load and connect

• Rotate on Horizon – Fastest way to adjust HDRI shadow direction
