How to make a radial blur post-process material in Unreal Engine 4 (version 4.20.3) using a custom HLSL node and a radial gradient. Topics covered: HLSL, custom nodes, post-processing, material graphs. Thanks to Joubert van Zyl for the request, and special thanks to Tomura for writing the original code in 2015.

hehe no worries! Hope this helps you out :) I saw NicolasNGD's post in the thread, where he builds out more of the material - I thought this simpler version was better for the video. Thanks for watching! :)

Hi, I think it is possible to use Gaussian filter instead of that model, it is an idea but maybe in the toon shading we use Sobolev filter to extract lines instead of subtraction which give us lines we could use add to give smoothing model, by the way thanks a lot for nice tut.

Wow, that's very useful! I think I will try setting the intensity with the charachter's velosity. then when the player falls fast or is standing on a train, it will look really cool and powerful :)

Thanks for the tutorial. I have some issues. Custom node seems doesn't work (I use Engine version 4.20.3). When node connected i have that brick placeholder texture in the material but not blur effect. I rechecked HLSL code twice - everything looks right. What could go wrong?

Hi, thanks for the great video. How can you make it, that in split screen multiplayer, it only affects one player?

@underscore00 5 жыл бұрын

You can do this by using a 'Create Dynamic Material Instance' node in the player blueprint, and by putting a post-process volume in the player pawn. I'll have to do a little testing to confirm, but that should put you on the right track :)

@OniBojan 5 жыл бұрын

@@underscore00 HI, thanks for your reply. But if I add it on player pawn, will other player see that blur? I'm making racing game, and want to blur the screen to a player that uses turbo (there will be Split Screen mode support). But I want to be sure that only player that uses turbo, can see the blur.

@JesseLeeHumphry 3 жыл бұрын

@@OniBojan You'll need to have an event that runs a timeline. You can use Set Settings with the Post Process component as the target. You'll then have to make an array of Weighted Blendables and define your "object" and "value" from there. Your value should change over the course of the timeline.

You should be able to find a post-process volume in your 'modes' tab and to make a post-process material, you select the main material node and change the material domain to 'post-process'. Hope that helps!

@underscore00 4 жыл бұрын

It's a scalar parameter. You can get them by either holding 1 and clicking the graph then right-clicking the constant and promoting it to a variable, right click the graph and search for 'scalar' in the drop down list, or holding 's' and clicking the graph. The last way is what I did in the video :)
