Hi Everyone, In this tutorial, I will show you how to make the post-process material based scan effect in unreal engine 4.It also uses custom stencil to highlight certain objects after the scan. We are also using a world aligned texture node to map a pattern texture on to the world. This tutorial was made in Unreal Engine 4.22.

Is it even possible to make the PP actually into an actor BP, making dynamic mat on the PP and edit the params from within that scan actor BP, spawn an actor that makes the scan when button pressed and then fade out the PP and then destroy actor. I've made almost everything except the dynamic material part. Unless I made a mistake somewhere, I only get the stencil effect but the scan lines are not showing up. So is that even possible/viable to do and is there any drawbacks/performance wise or whatever? I'll definitely post if I make it work and will try post somewhere how. :)

Thanks UnrealCG. One question. It seems that when I opened my project this morning the materials that were working fine yesterday arn't working anymore. I have a checkerboard Material display in the material editor and nothing I know of sseems to change this. Any ideas? It worked a treat yesterday. Also If I wanted to use this effect for a cinematic not runtime where would I put a time/speed expression? Any help would be appriciated:) cheers again.

Thank you, thank you so much for this tutorial. It's precisely what I was searching. Now I'm trying to re-create it on my computer but I'm incurring in a couple of problems. First of all, I need to scan three types of enemies. I've used a super-class father that give parental to the three child-class of enemies, but a couple of them have a static mesh and the other has a skeletal mesh, so I'm having problems to "light on" all of them at the same time. And in particular, I'm trying to obtain a real-scan effect, where you scan, the silouette becomes visible, then delay of 5 seconds and the silouette disappear (I've done it after the spheretraceforobject (setting the green array on Pawn it works. On worlddynamics not), and doing a cast tothe father class of the enemy, casting the Activate event, then delay and then the deactivate event). But I've obtained the disappear effect only on ONE enemy type. And only on one of it. If I try to use it on an other enemy of the same type, he will not light on. And I've seen that I obtain some effect only if I write the activate/deactivate blueprint on both father and child classes. I can use the "custom" in the details, setting On myself, but if I do it the scanned silouette remain permanently visible and it will be a little strange on a game. Do you have any suggestion to try to resolve these problems? Again, thank you for this video and I hope you can help me with these issue. Next time I'll try the invisible effect tutorial. It seems pretty amazing °w°

If you have two different types of actors, You could create two different sphere trace for them and connect them using a sequence node. You could also try using a multi sphere trace.

Is it better to use flip book and make effects in Adobe after effects, or use particle system for the HUD and user interface effects?

every object that are marked for to be highlighted, but not within the radius when player scans, will still be highlighted when the player walks towards it without scanning once more

I came down to the comments looking for the answer to that question... i thought about switching in runtime the value of material's Bits to a number not specified on the actors, and it does remove their highlight. But once you switch the Bit value back, the highlight is back too!

So even though you have to press F again you get the reverse animation coming back towards your player, which will also reverse the highlighted effect :)
