This week I had to animate material properties on a number of objects from Sequencer. That’s not a big problem when you can access the object directly, but in my case it was a blueprint that had several child blueprints attached (an array of lightbeam objects, each of which was setup with a dynamic material …
Sometimes you want to assign a material to a portion of an existing asset, but there’s just no zone setup to make that happen. Thankfully the Modelling Tools in Unreal Engine have tools to create and delete material zones from selections. It’s designed to be deliberately unintuitive of course, so here’s a quick guide on …
EPIC have implemented some changes in the way Media Plate actors are handled in Unreal Engine 5.5. In addition to the (still experimental) Media Plate plugin, there’s now a new Holdout Composite plugin/component combo available that’s enabled by default. Due to changes implemented therein, emissive plates can apparently handle image content better and even works …
Here’s the solution to a rather tricky puzzle I’ve spent researching all day. Imagine you had a Blueprint that’s made up of Child Actor Components (potentially other blueprints with their own logic). How do we access parameters on those children, and how do we do this via Sequencer or other blueprint logic? Quite the task …
I was working on my laptop in a doctor’s waiting room the other day, twiddling with the construction script of a Blueprint, when my trackball sort of slipped. Next thing I see is a completely empty construction script gaph, missing its root node. I could still move around drag other nodes in, but without the …
I had worked on the packed UV layout of a figure with the intention of using the resulting textures on the original model in Daz Studio. Trouble was, there was no way for me to import the new packed UV layout into the Genesis figure because I had modified the base model, so it didn’t …
I’ve just learnt how to override height information caused by a lower layer in the stack in Substance Painter. It’s an extremely simple trick I thought was worth mentioning. Let’s take this creepy mannequin character I’m working on as an example. It has metal caps on its arms, and although the colour looks OK, we …
I’ve recently worked out how to properly use the ZRemesher in ZBrush. It ccan create handsome topology from somewhat messy meshes. I had previously assumed it’s a one-click magic button, but learnt the hard way that it actually distorts meshes to the point of not being able to recognise them afterwards. Turns out ZRemeshing is …
Some plugins can cause trouble and keep the Unreal Editor from starting. When that happens, there’s no way to disable a plugin via the GUI. Thankfully it doesn’t quite mean “game over” just yet, because we can tweak our project’s configuration file to exclude plugins that may prevent a start. Here’s how to do it: …
Complex figures like humans are best UV unwrapped when they’re split into multiple parts, like arms, legs, head and so forth. When we’re working with Genesis or Reallusion figures, the heavy lifting has already been done for us, but when it comes to creating these splits from scratch it can be tricky. Here’s a way …
FilaToon is a new shader that’s been introduced in Daz Studio 4.23. The actual render engine to make this possible (Filament) has not changed and was actually introduced sometime in 2019, but it never did anything other than auto-translate Iray shaders under the hood for faster scene previews in the viewport. With FilaToon, the developers …
Last week I wanted to add a table cloth to a table and add a lace trim, so that it would match an existing item of furniture in our scene. I went through several iterations until I came up with a good workflow, and thought I’d share it with you. This took much longer on …
Flipping or recalculating normals usually requires a round-trip into a modelling app, but thanks to Unreal Engine’s built-in modelling tools, it can also be done “in-Engine” as they say. Let’s see how to do it! It’s a little hard to see from this screenshot, but the object on the right needs its normals flipped for …
Node graphs can get large and insane fast, and often it’s not feasible to drag wires across long distances and into multiple nodes. It’s impossible to decipher relatively simple stuff we’ve done weeks ago, only because the node setup got a little out of hand. That’s where Named Reroute Declaration Nodes come in. They’re really …
If you’re looking for the new Daz Premier Subscription features (aka the ManFriday Subscription), here’s where to find them. You’ll need Daz Studio 4.23 or higher, and an active Daz Premier subscription to use these. Search Install Manager for “premier” and install the currently five packages that show up and restart Daz Studio. Here’s where …
When you create a new level in Unreal Engine, chances are that they come with a pre-defined outdoor light setup consisting of the following items: I was wondering how to change the size of the sun disk in the sky to create more dramatic sunset scenes without resorting to a plugin like Ultra Dynamic Sky, …
Character Creator has a similar workflow to Daz Studio when it comes to importing and rigging clothing. We export the avatar, model/fit clothing in MD, export an un-rigged OBJ and transfer the skeleton and weight maps. Pitfalls lurk at every corner of course, so I thought I’d make some notes before I forget it all …
I’ve been tinkering with a flickering light effect. While it is possible to animate the intensity with Blueprint code directly, there’s an easier way that lets us use the intensity as an override and make the light flicker without futzing with variables. The solution is a Light Function. To create one, let’s make a new …
I had this warning in Unreal Engine 5.3 recently when opening a level and didn’t quite know what to make of it: “Spatially loaded actor references a non-spatially loaded actor”. Everything seemed to be working fine, and since it wasn’t an error as such, I didn’t worry too much about it. Curious about what this …
When you open an EXR file in Photoshop, it will ask you how the alpha channel should be interpreted (as Alpha channel or as Transparency). It’s great to have a choice, but it’s utterly crippling when you want to bulk open several hundred EXR files. There’s no native way to suppress this dialogue, or set …
I’ve turned several objects from a pre-built level into a Blueprint, with the intention of spreading it around as duplicates elsewhere in my level. There was no logic involved, it was just a collection of static meshes. I’ve dragged several copies of my Blueprint into the same level, and when I was happy with the …
The other day I needed to make some geometric changes to an object in Blender that relied on my object looking handsome when viewed through a specific camera in Unreal Engine. Hence the best way to work was to export the camera I had setup in UE, and it wasn’t obvious how to do that. …
Here’s another Unreal Engine oddity that many have come across, including myself: some actors in the outliner show as “unloaded”. You can’t navigate to them, you can’t right-click on them and make them show up, they just linger like a ghost. Here’s an example: This only seems to happen when World Partitioning is enabled and …
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 …
I was working on wrapping a character that had their mouth slightly open, and I didn’t have a controller to close it. Without a sculpting/modelling session, this would have been problematic to turn into a Genesis morph. Thankfully Faceform Wrap has an interesting node to close those lips using the Stick Contour feature. Here’s how …
I’m sure we’ve all been there: we want to adjust a property on our Substance material and realise, with some perplexion perhaps, that said channel doesn’t exist. Take this example in which we’re missing the opacity and the emission properties. What if my object needed one of those? How do we bring them in? This …
It took me a while to find the recipe for handsome looking creepy fog results in Unreal Engine with Ultra Dynamic Sky. Here’s how I did it, just so I can reproduce it next time I need it (section in brackets):
Some materials require static boolean inputs to apply effects. They’re easy to setup in base materials, but don’t translate into instances because they’re static. To give users the option to enable such booleans in material instances, we can use Switch Parameters. Here’s how to set them up on the base material: Instead of supplying the …
There is a neat way to turn static meshes into dynamic follower clothing in Unreal Engine! Since 5.3 there’s a Chaos Cloth plugin that ships with the engine, although it’s only really become usable in 5.4. It looks more complicated than it is, so let me walk you through the basic workflow in principle: Let’s …
Sometimes we may need to get rid of objects that clutter up our Blender scene. When it’s geometry that’s very easy to do: click on the object in the viewport or the outliner, the press X or delete and said object is gone. But what about unused textures, materials and material slots? Not so obvious …
