You can change the size of the shadow map. The lower this value, the more
pixelated the shadow becomes. If the parallel light cube boundary had a
dynamic value, these pixels would appear to jump, since the shadow map
would otherwise vary dynamically in its size. In order to prevent this, a xed
value is used and any such shadow jumps are eliminated.
Outline Shadow
This option results in a thin shadow outline instead of a full shadow.
When enabling this option, we recommend you use higher than usual values
for the shadow map’s resolution and sample radius.
Shadow Cone, Angle
One of the drawbacks of Omni light sources is that six shadow maps must be computed in total, which
can sometimes produce small artefacts at the edges of shadows. If Shadow Cone is enabled, the shadow
production is limited to a cone, thus generating a single shadow map that is free from artefacts. This also
has the advantage of speeding up render times. Set the vertex angle of the shadow cone using Angle.
Soft Cone
Enable this option to give the shadow cone a softer edge. This ensures that any object only partially
in the shadow cone area casts a soft, fading shadow.
