Creating a Fluid surface with Blueprints and Render Targets

FS_Header_Image.png

Using Blueprints and Render Targets, you can create a fluid surface that simulates what happens to water when it is hit by a projectile or player. In the following guide we will learn how you can use Blueprints & Render Targets to create a fluid surface actor by creating a new set of render targets and Materials that are specifically setup to work with render targets. We will then create and setup a new Blueprint that will contain and power the fluid surface interaction when the fluid surface is touched or shot at.

Part of this guide uses the same assets created in the Creating a Height Field Painter with Blueprints and Render Targets How To guide.
