Hey everyone, After the discussion on Lordink’s question [here](https://answers.unrealengine.com/questions/27771/focus-based-dynamic-dof.html) i managed to get a dynamic DoF system working using the blueprint FPS template. Here’s the end result; [![](https://d3kjluh73b9h9o.cloudfront.net/original/4X/2/3/5/235ff052d70a50cdc0767be912cc08aa5c0d3730.jpeg "Dynamic DoF - UE4") ](https://www.youtube.com/watch?v=rEargI8dNFk) ![DoF_1.JPG](https://d3kjluh73b9h9o.cloudfront.net/original/3X/b/6/b6338b04b90fec9b59ac7b3f162d39e42e91528f.jpeg) ![DoF_2.JPG](https://d3kjluh73b9h9o.cloudfront.net/original/3X/d/e/dea73eb17c1e0db5d8650d90314e17144e346008.jpeg) You can see the collapsed nodes and the macro together with the rest of the BP in full res. here; > **[Dynamic\_DoF](https://www.dropbox.com/sh/m0vjmtwqd16ylwa/AABHxm9heePiGUAgeshtkP7fa#/)** > > Shared with Dropbox -Blur type, scale, interp speed and trace distance depend on your project so you can set them as you like. You can also set the transition speed dynamically with a little more calculation. And you can increase/decrease Near and Far Transition Region by adding/subtracting whatever value you want to focus distance. -You need to set Max Bokeh Size inside the blueprint( **Make PostProcess Settings** node), otherwise it uses the default value even if you set it in the camera component’s options for some reason.

The last node has a ‘set’ for the post processing which also has a target input. How do you go about getting this node? I can make a struct but there isn’t the extra light blue input to attach my camera/capture2D to. Thanks. ---

You need to disable the bools for every property(especially Blendables) and enable only those you need if you want to work with them easily. https://.unrealengine.com/showthread.php?5938-PostProccessSettings-node-is-too-\*\*\*\*-long-!&p=45395&viewfull=1#post45395 Copy those and paste(ctrl + V) in the blueprint, and you’ll have post process settings nodes with every property disabled.

Hello friend, I really want to know if there is any way to make the UE 4.2 because the PostProcessSettings node it is very different, has only the Boolean options and you can not convert 😕 ---

Hey JHanziwest, I already answered you at AnswerHub. As i said, it is working for me in 4.2 as well so i’m not sure what the problem is with your node. Sorry. :\ ---
