Hello dear community, I’ve been using Unreal for ~5 days now so this might be a fairly dumb question. **What I want to achieve:** So I want to use Niagara to render some meshes made from particles and have it render with a tilt shift effect so only some of the emitted particles would be in focus. I want the particles in the front and in the back to be out of focus. **My problem:** While setting this scene up and using the “Cine Camera Actor”, I noticed that I couldn’t quite get the tilt shift effect that I wanted. Particles would be either completly in focus or completly out of focus. **Visualization of my problem:** I set up an experiment illustrating my problem. There are three cubes and the cine camera actor. Each of the cubes has a Niagara System on top: ![333051-setup.png](https://d3kjluh73b9h9o.cloudfront.net/original/4X/5/1/8/5185a8c32b45d69124e508918e7c235309eb9bf1.png) If I pull focus on the different cubes, the corresponding Niagara System should be in focus too, right? Unfortunately this is not the case. It is only when I put the manual focus distance very high, that the Niagara Systems are in focus again: ![333052-problem.jpg](https://d3kjluh73b9h9o.cloudfront.net/original/4X/d/a/1/da1f7995a4aec6aab26578c868657f06e796a885.jpeg) So why is the DOF of a Niagra System differing from the DOF from the cubes? Is it even possible to achieve a tilt shift look with Niagara Particles? Thank you very much! ---

Try to check this box in your particle material and see if it fix your issue: ![352045-particledepth.jpg](https://d3kjluh73b9h9o.cloudfront.net/original/4X/9/6/e/96ed102fb62e3d6e9f34d94926e5e9e4d4571023.jpeg) ---

I am having the same issue in UE5 now and this unfortunately didn’t help ☹ ---

Found it! There is a tutorial: [Particles Not Blurring Fix Unreal 5 - YouTube](https://www.youtube.com/watch?v=se15VZnaE4I&ab_channel=ShaunFoster) You need to switch settings of material used in Niagara system. In material deaitl type in “Translucency Pass” and switch to “Before DOF”.
