UE4 Niagara Quicktip Sticky Collision

Endresult can start to be seen at 1:40
This tip shows two things. How to make particles stop moving when they collide, and how to align them to the distancefield they collided with. You could use depth or raytraced collision as well, but then you have to rework the alignment slightly. Dive into the collision module to see what parameters are available to grab.
Not only for the normal, but dive in, and have a look at what transient values you can utilize later on in the stack. Tons of useful stuff in there!
HasCollided is a super useful bool that can be used to toggle anything. You could switch colors, swap out which renderer is used entirely and so on.
This method will not align sprites perfectly of course, and it will depend on the resolution of the distance fields. But it's often good enough.

Holymoly... this tip is ultra useful.

Hello Andreas! Love the videos. Why does this not work with ray-traced CPU collisions? It seems to set the collision properly for just a moment before swapping back to the default.

Hi Andreas! I'm a first-year student of the video game design and development bachelor, I would love to be specialized in FX, I have seen a post of yours in twitter with some special effects that I have found incredible! In my degree there is only one FX subject, since it is a generalist bachelor and we see a little of everything (animation, modeling, design, programming...). Could you guide me a little about what are the most important things to be able to specialize on my own in the field of special effects and to find a first job on this field? Sorry for the inconvenience and thanks for your time :)

Sure! I've created a wiki for this purpose. Check this page under prerequisites. There are a couple of articles that cover this. realtimevfx.fandom.com/wiki/Tutorials
