# PostFX Shape Weight Modifier Component

The PostFX Shape Weight Modifier component limits post-processing effects (PostFX) modifications to a volume that’s defined by a Shape component. The weight of the PostFX remains constant within the shape component’s bounds and falls off to 0.0 outside of the bounds according to the Fall-off Distance.
