Parallax & Bump Decals | 5-Minute Materials [UE5]

Hello! Today we're looking at Parallax Occlusion Mapping Decals, as well as BumpOffset Decals inside Unreal Engine. Many viewers have struggled to get POM decals working in their projects, so I figured I'd make this short video explaining what goes wrong and how to rectify it.
Parallax Decals are super handy for destruction effects and are widely used in the games we all play.

Thanks so much! I ran into the exact problem and couldn't solve it. No clue what epic was thinking and why this isn't the default pom shader

Man the amount of usefull information that you emit by the minute is incredible, the way you explain the reason behind your actions and decisions is very much welcome and neded, we don't see that from many other creators from the tutorials part of youtube. Thank you! I learned a lot from this video. PS: I'm really having trouble with shadows in the terrain, i've figured out how to use a little bit of the auto material mechanics. So there's that, any idea on what to focus my reasearch on, so I get to fix it?

Hey hey! Thanks so much :) BY shadow troubles, do you mean that ugly kinda square-looking shadows?

@elielsonanjos7440 4 күн бұрын

@@PrismaticaDev yeah those one, the top of hills get ALL squared Up on the shadows, It doesnt work at all. If I use Path tracing the shadows ARE correct but they have Sharp edges like they are low poly. Attention: I was not following your tutorial, I have a generic "me" made material that tries to be an auto material.

I saw soemthing similar in cs2 bullet decal but it wasn't the same shader tech lol

i haven't played with shaders in a while. for sure gotta check out the custom hlsl node and squeeze some more raymarching out of the engine. volumetric shading is bonkers. i have a perlin ice cave in a polygon in my lil test engine.

This is great! I'm only having one problem with this (or any POM decal honestly) : if I scale the Decal actor on the X axis, the effect completely breaks. Any ideas for how to solve this? I tried to use "Object Scale" and multiply the Height Ratio to "Scale X", but it doesn't seem to do anything.

Hey hey! Do you mean the parallax effect looks super banded? There's another more reliable way to get Scale, give me 1 sec to double check

@PrismaticaDev 4 күн бұрын

I believe if you get 1,0,0 and plug it in to a Local -> Worldspace node, then subtract it from the PivotPoint and get the Length of the result, it should be the "length" of the X scaling. I'll be able to test tomorrow

im just skimming through but does it also add the falloff distance for the camera? to only render things within camera vicinity

Parallex or bump has better performance than polygon model?

@PrismaticaDev 5 күн бұрын

@@JieDu-yj2vd In traditional rendering, yes. However Nanite tessellation could potentially be cheaper than POM if you’re using Nanite. Regardless, you’ll need to use parallax effects for decals :)
