I’ve often wondered how these “endless runner” type games are made under the hood. Julia and her team have recently released a project like that called Dash and Splat that was made in Core, and I wondered if I can make this work in Unreal Engine. After some research and tinkering, here’s one way to …
Sometimes I use the option to open a new window when preview playing my project in Unreal Engine. That way I can still keep an eye on other goings on in the editor while watching the action. The option comes up on the little three dots menu next to the play button. The new window …
Sometimes it’s the simple things that catch you out, like quick references. Say you wanted to access a property on your animation blueprint for something you’re doing in your player character. I couldn’t remember how to do this, so I thought I’d best make a note of it. Here’s how we can do that: This …
When a character dies, we can play a death animation either as a montage, or via the animation blueprint. In this quick tip I’ll explain the latter principle. We typically have a boolean (like “is dead”) that checks if the character has died, and it’s true, we’ll transition to a new state in our state …
I have a simple class that spawns x amount of enemy characters into my world, but by default they all use the same skeletal mesh. I wanted Unreal Engine to use a different mesh from a random pool of characters. I’ve used an array for this, create a random integer not larger than the array, …
Typically Animation Blueprints need access to the forward speed of your character. This can be done in a few different ways, and I thought I’d compile a list of options for every eventuality. If you know other approaches, please let me know and I’ll add them here. In your Animation Blueprint The easiest way is …
I’ve been dissecting an old project of mine and couldn’t remember how the projectiles I was shooting happened to magically fly away when they were spawned. They seemed to have an initial velocity or inertia in the forward direction, yet nothing in my Blueprint was causing this. Then I figured it out: we had added …
In a previous article I’ve explained how to trigger an animation with a timeline node. I thought it might be nice to see a different approach to the same problem, so in this article I’ll show you how to do this with a Level Sequence. The concept allows more flexibility on complex animations. In principle …
I was trying to implement an Aim Offset the other day and followed a particularly terrible tutorial on the EPIC site that didn’t work out at all. This tends to happen when we try to do something that’s beyond our understanding. One part in particular left me clueless, which is the process of editing animation …
A few years ago I’ve described how to rotate an actor towards a location with the use of the Lerp node. This thing can interpolate two float values and as such is a very multi-purpose function. I’ve just found out that Unreal Engine has a dedicated “rotation interpolator” node called Rinterp. It takes two rotation …
Animation Montages can be inserted into running animations when we feel something else needs to happen before the previous animation can continue. A good example is weapon recoil that happens as a result of firing a bullet: rather than switching to a completely different animation, we just cut to the montage for a moment before …
In a previous article I’ve explained how to put a gun into your character’s hand using the Attach Component to Component function. This works great if the component in question is a static or skeletal mesh, but it does not work for another blueprint class. Say you had a weapon and it has functionality, there’s …
Blend Spaces can mix animations together depending on value input. This can be used when say your game pad input determines how fast your character can walk, so that an idle animation is blended together with a walking forward animation. That way there’s no pop between each animation. Let’s take a look how to setup …
Unreal Engine 5 offers an exciting way to share animations from UE4 skeletons on the new UE5 skeletons. This works by way of a pre-configured IK Rig and Retargeter specifically made for this purpose, and an export option so that we’ll end up with a set of new animations that are ready to be used …
I’ve been meaning to make a note about the “attach gun” part, because I always forget how to do this. It’s relatively simple when you know, but not… well when you don’t. Let’s fix that! This procedure can also be used to attach other things besides guns into the right places, such as hair and …
The retargeting process has completely changed in Unreal Engine 5. It appears we can now use a system of IK chains that make animations from one skeleton usable on another by way of an IK Rig and IK Retargeter. It took me a while to comprehend this, but I’ve successfully managed to use this system …
Reacting to user input was always a little naff in Unreal Engine: define an input, then build a rather complex graph with booleans around it to see if a key is pressed or released, all of which using a section of the Project Settings to map the actual input sources and axis. It felt a …
Like most apps, Daz Studio writes a continuous text output to a log file with any status messages that are generated under the hood. The most obvious of these is the render progress window, as we can see each line update live while the render is happening. We can also read the full log from …
Text Objects can be formatted with a funky node called Format Text. It’s a very powerful little thing, even though at first glance it certainly doesn’t look like it. When you drag in a value, it is literally passed through without much change. However, if left alone as in the example above, we can use …
When dealing with float values, we’re often less interested in the exact value and can make do with a more human readable one. Unreal Engine has a couple of rounding functions we can use to make this happen: Ceil to Integer and Floor to Integer. Ceil rounds up, so 1.6 becomes 2 and -1.6 becomes …
Enums are a great way to create state lists with memorable names. Rather than having to remember numbers, we can create Enums and switch depending on phrases. This can be handy for game state switching among other things. We can create Enums by from the Content Browser under Blueprints. This brings up an empty list …
I didn’t know about a handy event that can apply damage to an actor, thanks to the OnTakeAnyDamage function. It’s an Event Dispatcher that Actor classes listen to, and if applied from another object, it’s really easy to pass on how much damage happened and also how it was caused. Consider this code plugged into …
Creating my first HUD widget in UE5 was a little disconcerting, as I didn’t see a reference to where any of my UI elements would end up on screen. Turns out there was an invisible default element called Canvas Panel in previous versions, into which we would place our UI elements. Thankfully this thing is …
The first thing that threw me in UE5 was the absence of that blue “make blueprint button” at the top of the scene outliner. No such option was obvious in the new interface, and a Google search yielded literally no results. Let’s change that, because I’ve figured it out! In UE5, we need to click …
Blender has a nice feature that allows us to merge vertices automatically when we move them into the place of an existing one. As an example, if I grab an edge of my subdivided cube and press GG to edge slide it over to the nearest one, there would be two vertices in the same …
I’m notorious at forgetting shortcuts in Blender: just as I had remembered that any viewport can be switched into a quad view with CTRL+ALT+Q, I was stuck with another problem: the views I was seeing were locked, and I couldn’t change say a back view to a front view, or a top view into a …
Here’s a high-level overview on how we can convert existing skin textures from older Genesis figure and use them with another generation, like Genesis 9. The principle is the same for the other direction too, should you wish to use a G9 skin on an older generation or perhaps a different figure altogether, like the …
I’ve recently made the above video about converting Genesis 8 characters to the new Genesis 9 figure. It’s been a runaway success and I felt we all might benefit from written instructions in addition. These are easier for me to update as new tips and tricks come to light, and link to other relevant resources …
I had a minor catastrophe the other day when all my Smart Content had seemingly disappeared in Daz Studio. I’ve had such things before and could fix it by re-importing all my metadata, but this time round it didn’t seem to work. I had to first reset the whole database, then employ a very specific …
Blender has a very powerful yet somewhat confusing re-timing feature. This comes in handy when you want to render animations at a different frame rate than they were designed to be in. As an example, you may have setup your scene with 24fps in mind, but want to render out a 60fps version, or vice …
