Hi everyone ! Thanks [MENTION=96229]Zarrashi[/MENTION] i tried your way but I can't see anything when I press play. I've create a material, I can Apply the changes without any error but when I launch the game I can't see the blur... Many thanks in advance for your help (sorry for my english).

Did you make a postprocessvolume and set the material as a "blendable"?

Well yes I think so, as you can see in the screenshot I think that I did the correct things... I'm new in the world of Unreal Engine so maybe I forgot something... Thanks for your help !

The material looks OK, but you need to assign it to a postProcessVolume and actually use it.

Great it works

I forgot to create a postProcessVolume ! Thank you so much !

Anyone manage to get this working on the HTC Vive?

Hey guys, this seems to be THE Radial blur thread. I'm having trouble reproducing the blur. I feel like I've copied the instructions accurately (I've not spent much time in the material editor so I don't understand most of it), but I'm not seeing the blur I was hoping for. You can see my nodes in the image below.

There's an error "Error [SM5] Material.usf(1270,21-50): error X3004: undeclared identifier 'View_ViewSizeAndSceneTexelSize" which I don't really understand. I also tried applying the post process to camera in my scene and got the result you see below. Not exactly what I was expecting.

[ATTACH=CONFIG]124620[/ATTACH]

Do you guys have any suggestions?

I'm getting the exact same error. Is "View.ViewSizeAndSceneTexelSize" no longer valid?

This is working in 4.14 for me:

Thanks, Kory! That code works perfectly for me. I've been trying to figure this one out for a while. BIG BIG THANKS!

**Dorian000** · 05-04-2017, 12:41 AM

Got this working in VR by multiplying the effect by two, one for each eye then mapping it all in UV space from 0 to 2.

**Benni.Lodge** · 05-26-2017, 08:20 AM

Hey there Kory (or anyone else). I've set up everything the same as above, save one thing. Where do I enter the material nodes code? Do I have to make a new code class? Sorry, I'm not very technical and I've been trying to get this to work for a while. Having done everything besides the material node code, I get this error:

If you look at your code you'll see you have sampleDist with a small s and it is complaining about not finding SampleDist with a big S. Change one or the other and you'll get it to work.

**Benni.Lodge** · 05-26-2017, 09:32 AM

Ah, thank you so much. No error. I'm still not seeing the effect though. I'm using the Rendering features in a camera component instead of a volume (it's actually a child actor with a camera component attached to the player pawn). Would this require a different kind of implementation?

I created a material instance like you did, with the same parameters, and have that as my post process material. Do I have to activate the PP materials some way (other than setting it's weight to 1)?

Don't worry, I've got it. It's just that I'm modifying other cam values which seems to be affecting it. Cheers for your help.

Since I've got the Blur working correctly I've run into another issue. The blur doesn't work correctly for split screen. I tracked down this thread: https://answers.unrealengine.com/que...litscreen.html where they say that post processing isn't working for split screen. Is this really the case? Is there any way for me to overcome this?

Is there a version for 4.15 and up? Because some of the nodes cannot be found!
