How to use

• Open the project.
• Run EUW_RainRippleGenerator Editor Widget Blueprint.

• After converting the render targets into static textures, don’t forget to set the correct parameters, including enabling streaming, mip generation, compression type.
• Experiment with generation settings until you will find a result that works for you.

Important Note

Depending on the project settings, particularly the Temporal Anti-Aliasing parameters used, a flipbook may create visible ghosting artifacts. Unfortunately, this is a specific feature of Temporal Anti-Aliasing and cannot always be resolved.
