Lazy Godray is an effect Blueprint for quick and isolated godray setup without the need of using volumetric lighting feature from unreal. This Asset combines all crucial components for making a nice looking godray effect into one Blueprint with a ton of customization options for that extra kick in completing the ambiance of your environment.


Features: 

- Lite weight geometry driven godray effect

- Customizable textures for light shaft effect & moving smoke

- Fully customizable volumetric options resembling the physical characteristic of smoke and volumetric lighting.

- Spotlight component and dust particle system to further pushing the visual fidelity of the effect. 

- Material can be used separately as fog material on simple cards & particle system.

Technical Details

All features are broken into sub categories in Blueprint setting. The ordering of the categories appears to be in random due to an unresolved unreal bug. It is advised to follow the numbering order when making your own customization.
