Methods

GetRtti

RTTIType *GetRtti() const override

Returns an interface you can use to access class' Run Time Type Information.

Fields

DirectionalShadowDistance

float DirectionalShadowDistance

Maximum distance that directional light shadows are allowed to render at.

Decreasing the distance can yield higher quality shadows nearer to the viewer, as the shadow map resolution isn't being used up on far away portions of the scene. In world units (meters).

NumCascades

u32 NumCascades

Number of cascades to use for directional shadows.

Higher number of cascades increases shadow quality as each individual cascade has less area to cover, but can significantly increase performance cost, as well as a minor increase in memory cost. Valid range is roughly [1, 6].

CascadeDistributionExponent

float CascadeDistributionExponent

Allows you to control how are directional shadow cascades distributed.

Value of 1 means the cascades will be linearly split, each cascade taking up the same amount of space. Value of 2 means each subsequent split will be twice the size of the previous one (meaning cascades closer to the viewer cover a smaller area, and therefore yield higher resolution shadows). Higher values increase the size disparity between near and far cascades at an exponential rate. Valid range is roughly [1, 4].

ShadowFilteringQuality

u32 ShadowFilteringQuality

Determines the number of samples used for percentage closer shadow map filtering.

Higher values yield higher quality shadows, at the cost of performance. Valid range is [1, 4].
