RemarksA CompositeShadow owns a collection of child shadows (see property Shadows). The CompositeShadow itself does not compute a shadow map (ShadowMap is always ). A shadow map is computed for each child shadow. The shadows of the child shadows will be combined in the ShadowMask of the CompositeShadow. The ShadowMasks of the child shadows will be .
Here ares some applications for composite shadows:
- Combine two CascadedShadows. One shadow covers a large distance and contains only static objects. The second shadow covers a short distance and contains only dynamic objects.
- Combine a CascadedShadow with a custom variance shadow map. Use the variance shadow map to create smooth shadows for distant hills. Use the CascadedShadow for detailed shadows of other objects.
