The purpose here is to create a basic scene with a sphere over a plane, nicely lighted.

This addition is simply a way to apply what you know about lights and to discover a few settings like colors or creating simple shadows.

Hemi lamps cannot cast shadows at all.Ĭreating a basic scene with basic lighting Only spot lamps can cast buffered shadows. Also strand-rendered materials (as can be used for hair or fur) cannot cast ray shadows with the Blender Internal renderer, so you have to use buffer shadows for them so their shadows look realistic.

The main difference is that buffered shadows are much quicker to calculate, but take more memory, and can be of lower quality without some fiddling. There are two different kinds of shadows that lights may cast: buffered and ray-traced. You might want to see the adjusted scene and play around with it for awhile. These are my lamp of choice for still shots, but they take a lot of time to render. As a result they can cast accurate raytraced soft shadows.

Area: These are similar to point lamps, except that they are rectangular.

Similar to Sun, its position does not matter, only its direction. Great for use as a fill light, or as a back light. Hemi: 180°-wide uniform, shadowless light source.They are also the only light source that can cast buffer shadows (see below). They are the only light source that can be made visible with the 'halo' option, to simulate light in a fog. Spot: Spot lights produce light in a cone shape, and have some special features.Good to use in brightly-lit outdoor scenes (i.e. Because the sun is (effectively) infinitely far away, the position of this lamp does not matter, only its direction. Sun: A light with parallel rays that will illuminate the scene with a bright even light.if there is a lightbulb or candle or something in the scene, position one of these within it to give the impression of light coming from that object. Useful for representing light sources within the scene e.g. The shadows can be sharp, or you can set its size to something nonzero to make the shadows fuzzy. 2 Creating a basic scene with basic lightingĮxplaining the Different Lamps.
