Example text

Everybody's workflow is different, but over the course of the next few chapters, we are going to follow this series of steps: 1. Evaluate what the scene we are lighting will require. 2. Plan how we want to lay out the lamps in our scene. 3. Set lamp positions, intensities, colors, and shadows, if applicable. 4. Add materials and textures. 5. Tweak until we're satisfied. Evaluating our scene Before we even begin to approach a computer, we need to think about our scene from a conceptual perspective.

Chapter 1 Other 3D programs refer to this lamp as a "direction light", but they all behave in the same fashion. [ 15 ] Introduction to Color Theory and Lighting Basics in Blender The Spot lamp The Spot lamp acts in the same fashion a spot light would in the real world. When we break it down, the Spot lamp is a default lamp attached to a cone, restricting the light to the volume of the cone. The settings for the size and length of the cone can be edited manually to fit different needs. [ 16 ] Chapter 1 This lamp is especially useful for scenes that require large contrasts in light such as scenes using a 1-Point light rig (we will discuss this later).

We have to explicitly tell the program to calculate them for our scene. Under the Lamp menu, there is a section for the Shadow settings, which is found directly underneath the Lamp settings we just adjusted. To enable shadows, you need to select the Ray Shadow radio button. This activates the shadow parameters, as we saw in the previous image. For now, leave these settings as they are, we'll play around with them later. Rendering out your scene now should result in something similar to the following image.
