There are three ways to extend Trapcode Shine's rays beyond the boundaries of its layer:
- Use RGS Grow Bounds plug-in located in Effects > Red Giant > RGS Grow Bounds.
Apply this to the layer and use the Pixels parameter to extend the layer's borders by a set amount on all sides.
- Pre-compose the layer (using the "Move all attributes..." option).
Then apply Shine to that composition.
- Apply Shine to an adjustment layer that is above the layer you want Shine applied to.
