Adding Gamepad Navigation for Menu Selections in Unreal Engine

In this article I’ll explain how to add gamepad and keyboard navigation to UI Widgets in Unreal Engine. To my surprise, gamepad navigation magically works alongside regular mouse navigation, as long as Keyboard Focus is set appropriately on any of our UI elements. We don’t need to add any special logic to our project. All …

What’s the mysterious red dotted line in Blender’s Viewport

Blender can define regions in the viewport that should be displayed rendered. That’s useful if we want to focus on a small portion of our scene. Rather than have the whole viewport displayed in rendered view, we can draw a border using CTRL + B, thereby defining a Render Region. This region manifests as that …

Something that sends the cold shivers down any animator’s spine. What is this madness you ask, and how can we restore it to …

Using an Opacity / Transparency Map in DAZ Studio (Iray)

Transparency is handled differently across render engines and file formats. While a PNG, TIF or GIF file can contain transparency data, a JPG image cannot. DAZ Studio’s Iray render engine can’t handle transparency data embedded in such images and requires the use of a special Opacity or Transparency Map. This might sound a little confusing, …

How to change the colour of a material via Blueprint in Unreal Engine

I’ve just learnt about a nifty mechanism to change parameters on a material node in Unreal Engine. The niftyness lies in the fact that when we convert static values in the material editor into parameters, which them become the equivalent of public variables that are accessible from other parts of UE4. It sounds way scarier than it is, let me how you how it works in detail and step by step.
