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.
Drawing text onto material
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.

There are two very important variables here. Create a Canvas Panel and make sure all the stuff you want curved is placed inside it.
You did it! Impress your friends. Thanks for reading! I only have one little issue that: my textures and all HUD elements have black borders now. Like Like. Hey Emir, glad this could help! Amazing tutorial! But how did you shift to screen coordinates? Some people use inertial math, but I found a super simple way to achieve a similar effect. I made a Scene Component blank component on my character blueprint that floats out directly in front of their camera on a spring arm so it sways aboutand then I tell the HUD on Tick to match the world coordinates to screen coordinates.UE4 - Tutorial - Pulsing Emissive Material
Hey, I was wondering how could it be possible to give curve effect based on its position on the canvas panel? It would save lots of effort Thanks! That gets into shader math which is not really my forte. By mistake I wrote 1. Aside from my own stupidity, this was VERY helpful. My sincere thanks. As for the guy years ago, maybe the dark edges come from the textures being Wrapped, instead of Clamped.
Like Liked by 1 person. Hey Zag! But I have a problem with outlines of my widgets.I couldn't make sense of my own work - wires running everywhere, material expressions all over the place. It took me few hours to sort it all out and it wasn't a very complex material. I can't have this happen again. It is my own material and I couldn't understand what the hell I did.
Even worse, if I had to give that material to anyone else they wouldn't know what to do with it. We probably wouldn't be friends any more. So here are 3 ways I organize all my materials in UE4. I now know what everything does and if I come back to it months later I'll continue where I left off. Each material expression can have a description that will be visible inside the Material Editor. A description can be added to any expression. Another way to add a description is go to Details panel and under Desc field, enter your text.
Adding comment boxes around a series of expressions is probably the best way to organize your materials. Left-Click Hold and Drag a marquee selection around series of material expressions. Do this to a series of expressions that perform something within the Material Editor. Reroute nodes are a way to create an "extension cord" functionality from which you can drag additional wires from.
Set Text Material
Below I have wires running from a single Clamp that goes through the entire material setup. This creates chaotic visual mess.
You can then reposition this Reroute Node and use it to connect to other Material Expressions helping you create a better visual wire flow:. Also, you can Left Click Hold and Drag a wire from a material expression then let go of the mouse button. Search menu will pop up. Search for Reroute and insert it:.

On World of Level Design you will find tutorials to make you become the best level designer and game environment artist.Ever since I first wrote about creating object outlines in Unreal Engine 4 I have wondered if it was possible to render them as soft outlines instead of harsh binary lines.
Overall it came to be too costly to come with a decent solution and so I stuck with the binary outlines you may have been in several of my earlier posts. Looks pretty decent, right?
Font Materials and Outlines
The effect is more expensive than the binary outlines since we perform several blur steps in the SpiralBlur-node to get to look decently smooth. Without going the custom engine route there is no way to downsample the post-process step where we sample and blur the information from the Custom Depth buffer.
Later in this post I will talk about performance of the effect itself. The built-in implementation takes the scene textures and over several iterations creates…. The default settings are at about iterations, which is pretty heavy! The node graph for it is reasonably simple and most of the logic happens inside the custom node which I added as a code sample below. You will want to keep the DistanceSteps and RadialSteps as low as possible while maintaining a smooth edge.
To conclude, the answer is yes! I imagine there may be more efficient ways of blurring the custom depth buffer to get similar results, I simply leveraged the available shader code to quickly get to a proof of concept. Automatically get new tutorials, free downloads, and other Game Dev content from me straight in your inbox! Hi Tom,thank you for this effect. May I ask you to answer this issue? Cesar, did you manage to solve this? Hope that helps. I can achieve this using your other outline setup, by just adding a oneminus after the Determine Occlusion set of nodes, and then multiplying that just before the lerp input, that worked great for that.
I see this is already occluding against the mesh that has Custom depth switched on. This really was just a proof of concept on the softness of the outline. The current material has compilation errors, so it will not render correctly in feature level SM5. Are you sure you wish to continue? Looks like you may not have specified any inputs in the node itself see SpiralBlur in the engine on how that works.
Seems that its complaining for the UV property is not connected, although you do not have it in the image either, so, there must be something I am doing wrong. Click on the main node in your material to access the properties and change it to be a Post Process. This will expose ONLY the emissive channel. If I remove that duplicate line from the code that goes in the custom node I get a bunch of other errors about missing declarations and not found Intrinsic functions. I tried this out in both 4.
Any way you could either send me a copy of the function or help me get it working? Much appreciated! This site uses Akismet to reduce spam. Learn how your comment data is processed.
Conclusion To conclude, the answer is yes! Any idea why? I cant get the material function to compile cuz of this. Hi Tom, this effect looks really good but unfortunately I get compiler errors in 4. Thanks and best regards, Daniel. An info on that would be awesome Tom Aaron. Hi Tom!Rendering text in a material. Posts Latest Activity. Page of 2. Filtered by:. Previous 1 2 template Next. Rendering text in a materialAM. Hi, I hope this is the right forum for asking this question.
I'm new to the engine and I'm trying to build a simple puzzle game. Each block would have the number displayed on one of the faces of that box. I have no idea on how to project text on an object, also I would like it to be one material for all the cubes and have the text given as a parameter. I assume its a pretty easy task for an experienced user. I would really appreciate your help, Amit.
Tags: None. Doing this in material only is not easy task, so if you insist or if its really that you need it as material, we can dig into that later There is "render text" component. You could make your block plus render text actor as single blueprint, expose on spawn text to render. Then manipulate those blueprint actors instead off blocks. Create variable that holds text to display, and maybe second for text color etc.
Expose them to editor and on spawn. But if you want more than ish of those blocks then indeed you need single mesh with material per one. So if you really need that display digit material: - give me exact shape of block, ie dimensions if its box, - which faces and orientation you want to have digits displayed, this is needed for uv mapping of mesh If i have time this weekend i can make mesh, material for it and uv layout texture. Comment Post Cancel. I added an image that shows what I'm trying to achieve.
Basically for starters I want it to be as simple as I can in order to distinguish between the tiles so I can test my game logic. Later on I might want to change the size of the puzzle and the material for the tiles and board have different sets and maybe even replace the text with parts of an image.
What do you think would my the simpler choice in order to get this working as fast as I can? Last edited by aofer ;AM.More results. In my football simulation game, I need the player's names and numbers to appear on the back of the shirts. What would be the best way to use that property and then display the name on the shirt?

I found this question looking for the same thing. I wanted a good way to do a Skyrim-like book with pages that aren't flat.
UE4: How to Create Your First Decal Material
In your case, you could probably use a flip-book node for each letter, but it'll get a bit messy. You'd need to create a really complex material node just to pull it off. Essentially, you'd have a flipbook texture with all of your characters, and then you'd call up the coordinates for each letter one by one, adding to the text mask as you go.
This would all go into a dynamic material, and you'd still have to figure out how to convert your database text into something that can be plugged in to a material.

The example explained in this article is creating a blend between a mud material, and a mud-leaves material using a mask Alpha texture. How does it work? There is actually no blending of Unreal materials, but rather a regular Unreal material in which each of the parameters is defined as a linear blend between 2 different source values for that parameter.
This complexity can be greatly simplified by collecting each of the participating materials parameters into a Material Attributes data structure. The Material Attributes data structure contains all the data needed to compile a material, and allows input, output, and processing of this data as a single blueprint data stream connection.
But designing 2 different materials within one material Blueprint is still far from being ideal. What if we want to use just one of these materials on some surfaces? What if the individual materials are not as simple as the materials shown here, it would be mush more efficient to be able to have one Blueprint for each of the materials allowing to focus on its development and preview it.
We can achieve this desired workflow by developing each of the materials as a Material Function. Each of the participating materials is created as a Material Function with a Material Attributes output. The Material Function defining the mud material:. The Material Function defining the mud-leaves material:. The Blend material using the Material Function nodes:. Note: When blending a non-metallic material with a metal material, the alpha values mask colors should be only 0 or 1 black or whiteotherwise blend areas that have a mid-range metallic value will make no sense visually.
Material Functions encapsulate shading flow graphs material blueprints into reusable shading nodes that have their own inputs and outputs. This allows development of custom shading nodes, and saving the time it takes to recreate the same flow graphs multiple times or even copy and paste material flow graphs. Common shading processes and operations that have to be performed in many different materials, and even multiple times in a single material can be defined as a Material Function for quick and easy re-usability.
Material functions can also be used to encapsulate a full material blueprint with a Material Attributes output. To use the new ColorAngleBlend Material Function create a new material, in the node search start typing color… to locate the ColorAngleBlend node and create it, and connect it to the desired material input.
