    Asset Pack
    This product contains an assortment of Unreal Engine assets which can be imported into a pre-existing project of your choice.

This package allows you to easily add dynamic weather effects to your scene. It is based on a single Blueprint controlling particle systems, post-processing effects, fog settings and decals to simulate a realistic weather system.

Control the Temperature and Air Humidity and enable Lightning Effects, Snow and Rain by customizing the Blueprint Parameters. Volumetric Fog Controls and some Sound Effects included. You can even simulate snow and water on objects by enabling the Decal Material that comes with the Blueprint. If you need real-time weather changes, simply use the 1D Perlin Noise generator inside the blueprint to affect temperature and humidity of the scene randomly over time.

In order to use the weather system, simply drag and drop the weather blueprint into the scene and configure the parameters you need.

Decal System requires DirectX12 when using Unreal Engine Version 4.22-4.24. Currently does not work in Forward Shading Mode.
