This level demonstrates ways in which Decals can be utilized in your levels. You then only need to apply a Decal Material, which is really just a regular Material that has had its Material Domain property set to Deferred Decal in the Material's Details panel.

As you move through the level, you will see a series of labeled plinths or displays. On each display is a number and short description, which corresponds to a section within this document. By cross-referencing what you see in the level with what you read here in the docs, you can quickly gain an understanding of how each example was created. For more information on how to use this example level, please see our documentation over Using Content Examples.

Some of the examples you see in the level may require you to Play Alt-P or Simulate Alt-S in order to see the full nature of the effect. In such cases, the display plinth will instruct you to do so. However, feel free to play the game in the Editor at any time and freely wander through the exhibits!

Post Feedback.Previous tutorial covered how to create a simple decal material entirely in UE4. Now, learn how to insert and use decals inside your level.

This will place an empty decal actor without material applied to it:. Once you've inserted a decal material into the level, it will automatically begin to project onto surrounding geometry.

Select decal actor and press Spacebar to cycle between move, rotate and scale tools. Choose the correct transform gizmo to move, rotate or scale inserted decal inside the level:. Performance will decrease depending on decal screen space size. So keep the size and projection distance small to only effect nearby surrounding geometry.

You can control which Static Meshes receive decals and which do not. For example, you may only want a decal to be projected on the wall and not the column:. You can replace already placed decal inside the level. Go to Content Browser and select new decal you want to use instead:.

Let's say you have a poster decal on the wall and you want to apply a blood splatter decal on top of that poster. To do this correctly, you need to define Sort Order for each decal.

Although, it is important to limit decal sort order projection to just a couple of decals to keep it optimized. Avoid having too many decals rendered on top of each other. But decals may still not show up. By default all decals use G-Buffer property and will not render show in static, baked lighting.

To make this work you need to enable D-Buffer option and change your material decal settings. This is a common problem and it is easy to fix. Want to learn more about creating custom decals for UE4?

Follow WoLD.Decal Actor User Guide. Physically Based Materials. Material Blend Modes. Material Expression Reference. Material Inputs. Layered Materials. Instanced Materials. Decals are Materials that are projected onto meshes in your level, including Static Meshes and Skeletal Meshes.

These meshes can have a Mobility setting of Static or Movable and the Decal will still project on them. Many Decals can be rendered at once without a large performance decrease. Performance decreases with larger screen space size and higher shader instruction count. You can then apply the Material to the Decal Actor. The Decal Actor is displayed as a wireframe box. There is an arrow always in the center that points in the direction of the decal projection.

The distance of projection for a decal is determined by the X-Axis scale of the box surrounding the decal sprite. As surfaces approach the extent of this box, there is a blending where the decal fades away. In the image above, you can see the decal projection on the back wall starting to blend away as the surface gets too far from the Decal Actor.

Even editing it in material editor is fine, but placing any POM decal material into an empty decal component causes complete freeze, instantly. Using just a basic material setup for POM Decals I'm not seeing any performance hit that you've described or any problem applying the material to a decal actor. Can you provide the full material setup you're using or a simple project attached here for me to test? Without the full material setup that you're using I'm not sure if I'll see the same thing on my end.

The basic setup I have isn't causing any issue that I can see.

Thank you for the test project and material setup. I was able to see that this was causing a Video driver crash. I recreated this project in 4. I've submitted UE to see if this one can be investigated and if it's something that is caused by UE4. Hi, totally sorry to revive such an old thread. Just a question. This is supposed to be fixed inbut we are curious to know what the bug was.

Alas, we don't have access to the subproject. And UE is nowhere to be found in changelogs. Is it possible to know where this was merged in UE4's P4, and for which files? Thank you. So the fix was verified in our Dev-Platform CL stream. However, you shouldn't be experiencing the issue if you are working in 4. I am not sure what you mean by, "what the bug was" as it is just a crash when using the POM node with a deferred decal material.

I'm still fairly new to all the technical bits, but from my understanding he's using the floating geometry method most people are also using in this thread and in Star Citizen. The bit I'm not too sure of is when he says "with UV's of the geo is the same the surface below. Is this referring to the same method currently used where the UVs are adjusted to the decal map and placed on the geometry? Or is it referring to something a bit more complicated between his decal geometry and the UVs of the geometry they are placed on?

I'd be interested in incorporating some POM decals into my workflow at some point, as it appears 4. If anyone had any insight into what he might've done in his shader I would love to give it a go and learn more about it! Toggle navigation Polycount. Millenia Polycount Sponsor. Jan Obscura said:. A technique that is accessible and usable in a proper way, for almost noone still lol. In Unrealthey made it possible to slap the decal material on meshes, but it still can't "overlay" and you need to hack with the opacity and normal intensity.

Because I would have so much better control over how things gets blended. Lets hope that developers will notice the need and we will get better support in the future. Great information!

I would have question how to approach welds in perpendicular areas using decals. I'm struggling with proper normals for them. I'm using UE4 DBuffer decal material with alpha masked normal only but my main issue with his technique is how to handle decal creation when areas I try to cover are welds on steel beams, pipe to pipe welds etc.

In general how should I proceed with creation of this Dbuffer Decals meshes? Texture and shader for it is all right, what I'm strugling with is good workflow to create this decal areas. I'm not even sure if I should use chamferred planes flat decal strip or L shaped strips to produce convincing shading for welds.

I'll try to post some images soon as I have pretty large numbers of assets that need this. For main shader I use world aligned tiling material. That one I might rework to object aligned, decide later, so far main material is working good but decal mesh normals drive me crazy, tested various normal thieves but none of them produced good result so far. Obscura godlike master sticky. In my opinion, that should work just fine.

Yep, here is a quick one. The L shaped "sopport loop" kind should work too.Do you want to add dirt, stains, leaks, blood splatter, stenciled numbers, posters or graffiti on the wall? One way is create a new texture variation with added detail baked into the texture itself.

So you end up with one clean texture without any detail and second texture with added detail, such as a wall stain leak for example. But, what if you want to have that detail in a different part of the wall? Top instead of bottom? What about having that stain leak detail on totally different texture in another section of the level? Well, that is another texture you would have to create. Apply a decal to one part of the wall but not to another. Resize the decal to fit a specific Static Mesh and you can even control which geometry receives projected decals and which does not.

Decals are materials that can be projected onto existing geometry Static Meshes, BSP brushes or Skeletal Meshes that are already placed inside the level. Counter-Strike: Global Offensive - paint decals on the wall, floor trash decal. Crysis 2 - wall leaking stain decal. Decals are one of the best ways to add additional detail into a level without having to create a new texture or material variation.

Before we jump into creating custom decals you must know the basics first. Decals could get very complex, especially when dealing with texture transparencies and opacities.

So, let's create a simple decal entirely inside UE4. This will show you the essential steps you need to know. Launch an existing project or create a new project.

Create a new material by using the Add New drop down menu in Content Browser and selecting Material:. One side note is that Translucent blend mode does not work in baked, static lighting. See this tutorial on how to make decals work in baked, static lighting. Want to learn more about creating custom decals for UE4?
