Drop shadow effect
Add a drop shadow under your object's visible on the layer.

Parameters
- Distance and Rotation set how far the shadow is offset from the object and in which direction the light is coming from.
- Blur softens the edges of the shadow, and Quality controls how smooth that blur looks (higher values cost more performance).
- Color of the shadow and Alpha define the shadow's color and how opaque it is.
- Enable Shadow only to hide the object and keep only its shadow, which is handy to render the shadow on a separate layer.
