3D lighting is an integral part of a 3D model, but it can take time to get right. A single light source can create shadows, highlights, and ambient light that lights up the entire scene. Have a look at 3D lighting techniques below:
Shadows are one of the most basic and effective ways to create depth in a scene. If you’re looking at a flat 2D image, it might look like there is nothing there—like it’s floating in space. However, when you add shadows, suddenly, the object feels like it is sitting on top of something else. And this can be as simple as adding a single black outline around an object!
It doesn’t have to be just black outlines either; sometimes dark gray or even blue-gray hues can help give your objects more dimensionality too! Adobe 3D AR says, “Different types of light — bluish, yellow light, and pure white, for example — will result in different moods.”
Ambient lighting is all the general light that fills a scene, whether it’s natural or artificial. Ambient lighting is a way to set the mood for your scene and create depth in your image. Ambient light will help to hide imperfections in your model and make it look more realistic. It also helps create shadows so that your object looks like it’s casting one onto another surface.
Blocking Lights is used to hide an object from a light source.
- The blocking light casts the shadow of an object.
- The blocking light can be a light source or an object, depending on how you want your scene to look like.
Reflections and Refractions
Reflections and refractions are two lighting tricks that can be used to create realistic effects in 3D models. Each of these techniques requires its own type of material to work effectively, but once you know what you’re looking for, they’re easy to recognize and reproduce.
Reflections are mirror-like images of objects that can be seen in a surface like water or glass. They’re caused by light bouncing off the surface at an angle (for example, if you stand across the street from a window).
A 3D lighting tool can help you design better lighting, which reduces design problems and saves you time and energy in the long run. It helps avoid faulty workmanship too—no one wants that
