A commonly used visual effects technique is rendering Texture and Materials to 2D camera-facing planes, which are called sprites. In the following How-To, we will set up a Niagara Emitter to work with sprites. When the Niagara System containing the Niagara Emitter is placed in a level, it will display your effect correctly.
This How-To uses the M_smoke_subUV Material, which can be found with the Starter Content. If you have not done so already, make sure that this Material or the Starter Content has been added to your project.
