The Ambient level on the Environment dialog establishes the scene’s basic illumination level before any light sources are taken into account, and is the dimmest any portion of the scene can ever become.Īmbient light is most often used for exterior scenes, when the sky’s broad lighting produces an even distribution of reflected light to surfaces not in direct sun. Ambient settings determine the illumination level of surfaces in shadow, or those not receiving direct illumination from light sources. To design using physically based energy values, distributions, and color temperature, you can create photometric lights.Īmbient light in 3ds Max simulates the general illumination from light reflecting off diffuse surfaces. Special lights are usually brighter than the fill light but less bright than the main key light. In stage terminology, these lights are known as specials. You can also add lights to emphasize secondary subjects in a scene.
Ambient light can be another element of your fill lighting. In 3ds Max, a spotlight is usually best for the key light, and either spotlights or omni lights are good for creating the fill lighting. It also emphasizes the three-dimensionality of the scene. Key-and-fill lighting emphasizes the subject of a scene. When you use only one fill light, the angle at ground level between it, the subject, and the key light should be approximately 90 degrees. Fill lights are less bright than the key light. In addition to the key light, position one or more other lights to illuminate the background and the side of the subject. Position the key light in front of the subject and slightly above. The subject of a scene should be lit by a single bright light, known as the key light. You don’t have to follow the guidelines, of course, but then you call attention to the lighting itself, rather than to the subject of the scene. The following guidelines are for creating normally lit, easily legible scenes. Outdoor scene with natural twilight and one streetlightĪrtificial light, whether used indoors or outdoors at night, uses multiple lights. Shadows are more distinct the clearer the day is, and can be essential for bringing out the three-dimensionality of a naturally lit scene.Ī directional light can also simulate moonlight, which is white but dim compared to the sun. When rendering with mental ray, you can gather skylight from a daylight system efficiently into an interior with the mr Sky Portal. A single daylight system is appropriate as the main light source for sunlit scenes. At sunrise and sunset, the color can be more orange or red than yellow.ģds Max provides several daylight systems to simulate the sun. Particles in the air can give sunlight an orange or brownish tint. Cloudy weather can tint sunlight blue, shading into dark gray for stormy weather. In clear weather, the color of sunlight is a pale yellow: for example, RGB values of 250, 255, 175 (HSV 45, 80, 255).
The direction and angle vary depending on the time of day, the latitude, and the season. At ground level, for practical purposes, sunlight has parallel rays coming from a single direction.
