You will need to judiciously adjust the lumens and/or reduce the specularity of textures or your characters will explode into a swarm of fireflies. Note that concentrating the light rays like that will increase noise.

You want a small width, a small angle, and a high exponent.ġ0cm, 10 degrees, and 50.0 exponent will do for a start. An exponent of 1.0 will spread the light rays evenly across the light's surface, an exponent of 100.0 will pack them all into the center. Each light has a certain amount of 'power' the bigger a light is, the more that power is spread out and the gentler it becomes. You can adjust its sharpness by changing the angle, the beam exponent, and the width (in order to change the width, you need to set the geometry to something other than 'point'). The width is the size of the light source, the angle is the size of the cone it projects, and the exponent is how much the light is concentrated.

To get really sharp shadows, create a spot light and aim it at your characters. I don't use distant lights-since HDRIs do the same job and better-so I'm not that familiar with them.

Can you give me some tips to get sharper shadows?
