- DepthBias (DepthBias) <float>
- DepthBias is offset added to depth values in shadowmaps.
Examples
DepthBias - 0.0002
DepthBias - 0.002
DepthBias - 0.0000000002
- SlopeDepthBias (SlopeDepthBias) <float>
- Slope Depth Bias used for surfaces having aliasing due to steep angles with light.
Examples 
SlopeDepthBias - 0.2
SlopeDepthBias - 8
SlopeDepthBias - 20
- NormalBias (NormalBias) <float>
- While rendering objects into shadowmaps, each vertex will be moved along -ve Normal direction, giving it an appearance of shrinking while rendering to shadowmaps. This property determines the amount of Units to be moved. Helps with shadow aliasing.
Examples 
Note:You will not see any changes if your material doesn't not provide bumpmap.
NormalBias - 1
NormalBias - 5
NormalBias - 20
Important:Increasing this value will make shadows between different surfaces less accurate, greate example is third picture in examples, there you can see "two" shadows from railing.
Bug:Numbers lower than 0.8 can cause huge graphics issues. Example.
