A ten-minute Sequencer trick to make static crowd characters look alive: an additive FK Control Rig loop with asymmetric breathing timing, desynchronised per character — plus an accidental discovery about copy-pasting whole Control Rig tracks.
Sane animation apps typically have a layer system that lets us make non-destructive changes on top of a base motion. Unreal Engine 5 introduced this relatively late in its lifecycle with version 5.5, but it works well if you know how to use it. Let’s take a look at where to find it and how …
In this article I’ll show you how to take a character from iClone with an animation applied, import them into Cascadeur to make changes, then bring the animation back into iClone. The official documentation is a little outdated at the time of writing, and thankfully this pipeline has been greatly improved. This works with CC3+ …
We work a lot with animated image plates, typically of rotoscoped actors (Unreal Engine calls them Media Plate Actors). That way we can position and integrate them into the 3D world. One of the hard parts is moving the camera to a different position while leaving the plate sizing intact as we make changes to …
The brief is simple: you have an object, and we want it to move along a path. Something that many animation apps have built-in by default is not so easy or obvious to implement, unless we code this functionality ourselves in Unreal Engine. Because that’s how hip and cool UE users have to be. Why …
I had an interesting issue today with rendering cloth simulations with Movie Render Queue in Unreal Engine: my cloth was either not showing up at all, or it was royally freaking out, as illustrated in the above screenshot. I spent two whole days testing and researching, until I found the issue my animations were having: …
I like using iClone as animation front-end for Unreal Engine. Although a lot can be done directly in UE, not everything is as convenient to achieve as it is in iClone. The pipeline is designed with humanoid characters in mind and works well enough, but things get hinky when it comes to non-standard characters like …
Spring Effects in iClone are “faux physics” if you will, something that lets a skeletal mesh bounce as it moves. We can create this from scratch on custom figures, and it’s a little finnickety to setup, but very straightforward if you know how to do it. These effects are not baked to the timeline (like …
Alembic cache files play back automatically in Blender. At first it seems we have very little control over how this happens, but when we take a closer look at the Modifiers Tab, we’ll see that that’s the place where all the magic happens: We’ll see some path information and a Time section. Expand it to …
I’ve recently picked up Sky Creator by Dimitry Karpukhin. It gives much more fine-grained control over cloud creation than what I’m used to from Ultra Dynamic Sky. It also contains rain and surface puddle effects. Naturally I wanted to animate the clouds with sequencer and make sure the way the clouds evolve is the same …
The simplest way to animate a morph target directly in Sequencer is by writing a small helper function that sets the timeline’s value in the Tick Event. The morph targets themselves can be Shape Keys made in Blender, and their names will be retained. It is also possible to import morph targets into our mesh …
iClone only shows a frame-code in the timeline by default, but that’s not helpful in all situations, especially when you’re switching between applications. If you need to make a 40 second clip in iClone, you’ll have to so some calculations we might not have mental energy for. Thankfully there is a (workaround sort of) way …
Sometimes we need objects to fade in and out in our animations, but sadly not every material lets us do this. Those that are designed with any kind of opacity in mind will already have a map plugged into the respective channel, and it’s easy to designate a scalar parameter with a multiply node and …
iClone has two concepts of parenting one object to another: Link and Attach. They’re slightly different. Attach is like traditional scene hierarchy parenting and good if you want to marry one object permanently to another (the parent moves, the child also moves). Linking is similar but can be animated for durations, so a bottle on …
We’ve been working with multiple 4K image plates in Unreal Engine, which is a great way to combine live footage with 3D environments without the overhead of a fully fledged virtual studio production. The more plates we used, the slower UE got – much like a video editor would if you stacked more tracks onto …
I’ve previously talked about using Shot Tracks in the UE Sequencer. There’s a related feature called Takes that I’ve just found out about. It can make life easier as you try things out while you work with animations and adds an “alternate” shot that can be swapped out without destroying the original. Each take is …
By default, Ultra Dynamic Sky calculates cloud movement continuously, no matter if you’re running game mode, simulation mode or if you’re working with a Level Sequence. There is a way to make sure the clouds form the same way as you move the playhead so that we get predictable results in our cinematic keyframe animations. …
Sometimes, and despite out best efforts, or as a result of copy/paste actions, actor references in Level Sequences can break. Anything that may have been tracked and properly working last time is shown in white (like the audio above), while things that have broken references are shown in red. It’s annoying when this happens, but …
When you’re using Unreal Engine animations as part of linear keyframe animations in a Level Sequencer, forward motion may become an issue. Depending on the situation, animators like to have the option to have say a walk cycle “in place”, then add the linear forward motion manually to direct a character in a cinematic. Sadly …
I’ve finally worked out how to properly create and render animations from Unreal Engine. The concept is very elegant, but also very different from most other 3D applications that I’m familiar with. This threw me on more than one occasion and lead to multiple frustrations, so let me share what I’ve learnt and explain the …
The Media Plate actor is a new object that UE 5.1 and above can automatically create when you drag an image sequence into your scene. Most of the heavy lifting is not exposed and happens under the hood, which is why I’ve had some issues playing the sequences back in Sequencer, due to the lack …
Most 3D apps have a concept of 2D planes that can show pre-rendered images and videos. They’re often called billboards, splats or simply image planes, they usually involve transparency and they’re a great way to conserve some rendering power. The principle is used with LODs as well, where usually the lowest LOD is a flat …
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 …
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 …
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 …
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 …
