This module must be placed immediately before the solver module. When using this module, the Alignment setting in the Sprite Renderer must be set to Custom Alignment the Facing Mode must be set to Custom Facing Vector and the Custom Facing Vector Mask must be set to 1, 1, 1. By default, the plane is defined by the collision module's returned collision plane. This module aligns a sprite to a plane over time. This retains the in-camera particle size by taking into account the camera's FOV, the particle's camera-relative depth, and the render target's size. This module offsets the particle along the vector between the particle and the camera. Update Beam recalculates the spline positions in each frame, to allow for beams with dynamically changing start and end points. Useful for sprite facing along a beam-style path, or to be used with the ribbon renderer for a classic-style beam. This module places particles along a bezier spline, or simply along a line between two points. This module scales the initial beam width by a user-defined scale factor. The ones listed here are just the ones that are automatically included with Unreal Engine. Keep in mind, you can create custom modules for any part of a Niagara system or emitter. Modules are executed in order from the top to the bottom of the stack.Įach of the module types in the Particle Update group has its own section in this document, with tables that list and describe the default options available for that type of module. Modules in this section should update new values for this frame. Particle Update modules are called every frame, per particle.
