"One Buggy Day"
Added on: Wed Nov 21 2001
Page: 1 2 3 5 

To increase the shadow detail and the effect of omnipresence of the skylight, the 8 spotlight ring was instanced and placed slightly above the bug.



TIP: I created one light and instanced the others from the first, so that when I change the parameters for one of them, the others will change accordingly.

The ground represents the largest source for bouncing light in the scene. This effect is recreated with another ring of spotlights, placed under the ground, casting a brown/gray color on the bug's ground facing areas.

At this time the ambient light is ready, and only one more light source is needed: sunlight. For this purpose, one spotlight with a slightly yellow color and a relatively high value of intensity was created. This light produces the specular highlights
and casts the sharp shadows in the scene.

TIP: I usually save a lot of time by substituting the complex geometry with a simple sphere to perform the illumination test-renders. This sphere, with a light-gray color and a detailed bump map applied, reflects the light's variations in tone and intensity, representing an effective method for the overall calibration of light in a scene.

When a satisfactory result is achieved, the original geometry is replaced and the light sources' parameters are fine-tuned.
