The Art of Mirror's Edge

Posted April 11th, 2021 in game-art

One of my favourite games is Mirror's Edge (2008) because its art stands out above all else. I would not recommend it for its gameplay or story, but it has served as an inspiration for me in terms of environment art and level design.

This post takes a walk down memory lane into Mirror's Edge, with lossless 1440p screenshots taken straight from the Steam copy of the game (no processing). I also wanted an easy-accessible record of the level art for my own archives, since it's mostly a showcase of what great artists can achieve with standard rendering tech.

Cityscapes

Probably one of the most iconic features of the game are the broad cityscapes. These typically consist of rooftops with a lot of verticality provided by ledges and HVAC systems.

One thing that really sells these scenes for me is the scale of everything - the low-poly distant buildings blend right in with the detailed foreground. In addition light and shadow plays a big role, with buildings obscuring sunlight and objects on rooftops casting massive shadows.

Capturing and Uploading Screenshots in UE4

Posted December 20th, 2017 in game-development

For Estranged, I wanted the ability to capture the contents of the frame buffer, compress it, and upload it to a REST API. This allows users to attach screenshots to an in-game feedback window, to simplify the bug reporting process.

Unreal Engine 4 has APIs around all of those pieces, and in this post, I'll cover sticking them all together.

The full header and source file from the Estranged code is available as a GitHub gist. Below are the important excerpts.

Capturing a Screenshot

This is a two step process. First, you need to register a callback for when the screenshot is captured, then you request a screenshot:

void UEstScreenshotTaker::RequestScreenshot()
{
    GEngine->GameViewport->OnScreenshotCaptured().AddUObject(this, &UEstScreenshotTaker::AcceptScreenshot);
    FScreenshotRequest::RequestScreenshot(false); // False means don't include any UI
}

void UEstScreenshotTaker::AcceptScreenshot(int32 InSizeX, int32 InSizeY, const TArray<FColor>& InImageData)
{
    // See below
}
