Remarks
Allocates texture space for the shadow-map and stores the shadow-map's raw data for deferred encoding. If the shadow-map has no shadows in it, it will return NULL.
Parameters
| Name | Description |
|---|---|
| Component | The component that owns this shadowmap |
| InstancedShadowMapData | The raw shadow-map data to fill the texture with. |
| Bounds | The bounds of the primitive the shadow-map will be rendered on. Used as a hint to pack shadow-maps on nearby primitives in the same texture. |
| InPaddingType | the method for padding the shadowmap. |
| ShadowmapFlags | flags that determine how the shadowmap is stored (e.g. streamed or not) |
