Water Library Aquatiq Water Addon Water+Fountains

Add water effects to your scene super quickly with aquatiq. Instead of spending hours creating complex simulations, you add simple planes with animation sequences that can be previewed in the viewport, or add procedural assets and effects to spice up your scene.

The library contains 2D and 3D water assets that can be used as legos to build new effects and assets like fountains, birdbaths, and water materials, it also contains
procedural generators for rain, river or puddles

The water shader that comes with aquatiq is called waterial and is also sold separately. It is an advanced material for creating animated water surfaces with low memory requirements and is much less performance-intensive than simulations. Descriptions in the node group make changes to the material rather easy.
