Unreal 5.1 - How to use decal projections with Niagara particles (2d and volumetric)

In this video I'll how you how to use 2d and 3d decal projections with Niagara particle systems. In theory you can use a component renderer but performance is horrible and it doesn't work half of the times. (This technique will be used in the next video in the cinematic VFX series) Note: Credit to this technique goes to Niels Dewitte who shared this on the real-time VFX forums. Enjoy!
