 solution
is to have multiple lights but only one directional light generating
shadows.</p>
<p>Yet another solution is to use lightmaps and or ambient occlusion maps
to pre-compute the effects of lighting offline. This results in static
lighting or static lighting hints but at least it's fast. We'll
cover both of those in another article.</p>
<p>Another solution is to use fake shadows. Make a plane, put a grayscale
texture in the plane that approximates a shadow,
draw it above the ground below your object.<
