So we use Photoshop to basically export them into PNGs or maybe touch them up a little bit if they need a little bit of love or a little bit of tweaking.

Our UI artists also use Unreal Engine 4, and this is because they not only just design and draw the UI elements, but they also do some of the programming for it as well.

So they need to use blueprints to script the UI elements to work the way that they want.

They use a thing called UMG, which is basically the UI

I guess you could call it in Unreal Engine 4, like a layout tool and things like that.

So they use UMG to set up their UI elements.

And they also work with some shaders, which are basically small scripts or programs that run kind of on the graphics card.

And they use that to manipulate certain UI elements to do certain things.

One example is, for example, the fluid animation on pipes, for example.

There's actually no animation on the artwork of that.

There's no waves or anything like that.

That's all created using shaders.

Our UI and UX people also use Microsoft Visio and YEd.
