UI distortion in Unreal Engine

In Breached we have a lot of digital noise/glitch effects. While we mostly used the wonderful “Sci-Fi and Glitch Post-Process” package, I’ve wanted to add a bit of uniqueness to UI noise effect and assembled a material function for distorting UI texture UVs.

Glitch effect in Unreal Engine 4

It uses a bunch of procedural noise generators, panners and a texture mask to apply specific distortion pattern.

DistortUV function

The function turned out to be quite flexible, so I’ve thought it could be useful to share it. You can grab archive with the function and texture mask here: http://goo.gl/5WBkmC

Just drop the unzipped folder to UE project and the function should become available as “DistortUV” node.

Dark Matter VFX

A while ago, working on Breached, I’ve been figuring out how to visualize a weird in-game creature called “Keeper”. It was something like an electromagnetic anomaly, stalking around and hunting for player.

The project is now using another engine and concept of those creatures completely changed, but I kinda liked the effect and decided to share it.

Blend Modes in Unity

You’ve probably heard about blend modes available in image and video editing tools like Photoshop or After Effects. It is an important technique for content creation and has long since become an integral part of them.

But what about video games?

Say you need to use Color Dodge blending for a particle system. Or your UI-artist made a beautiful assets in Photoshop, but some of them are using Soft Light blend mode? Or maybe you’ve wanted to create some weird Lynch-esque effect with Divide blending and apply it to a 3D mesh?

Blend Modes in Unity game engine

In this article I will describe the mechanics behind popular blend modes and try to simulate their effect inside Unity game engine.
