Lighting is the single most important aspect of 3D rendering because it controls how your objects and scenes are illuminated. Lighting is an important part of any 3D work, whether it involves animation, housing (as you have seen here), video games and many other places.
Types of 3D Lighting
Key Light
The key light in your shot. It outlines the subject and casts the darkest shadows. This is usually the brightest light in the scene and it sits off to one side of your subject.
Fill Light
This light fills in the shadows produced from the key light. It almost always goes on the oppsite side of the key light, and is at a lower intensity so that it can fill in shadows without making new ones.
Back Light (Rim Light)
The backlight, placed on the backside of the subject silhouetted by the light, gives a bit of a glimmer or halo around your subject to distinctly separate them from their background.
3D Lighting Techniques
Three-Point Lighting – The most popular lighting term combines a key light, fill and back light to make well-rounded and realistic looking scenes.
Global Illumination: Works by simulating how light reflects and diffuses off surfaces across the scene, providing softer and more natural lighting.
HDRI Lighting: It uses High Dynamic Range Imaging (HDRI) maps for rendering the real lighting by considering a perfect illumination of a Scottsdale environment.
Tips for Effective Lighting
Avoid Harsh Shadows: Artificial shadows will make it look fake. Soften shadows for better realism.
Adjust Light Intensity: You should get familiar with each light, and their properties to avoid too bright; or too dim scene.
The real benefit of perfecting these basics is your renders will look much more lifelike and aesthetically pleasing.
