Water Caustics - UE4 Materials 101 - Episode 27

Описание: In this week's Unreal Engine Material Editor Tutorial, we create the caustic patterns created by the ripples on the surface of the water and projected down onto the rocks under the water. To create the caustics, we're using a Deferred Decal object with a shader that projects the textures from the top, front, and sides in world space.
