One of Horizon Forbidden West's most technically-impressive moments is a hug

There's a lot of reasons to be impressed by Horizon Forbidden West, but one of the most technically-difficult moments in the game is when Aloy hugs another character. 

In an interview with IGN (opens in new tab), Guerrilla animation director Richard Oud discussed the intricacies of letting Aloy hug someone in Horizon Forbidden West's Burning Shores DLC. The discussion surrounding this sweet moment in the game started after Strange Scaffolding studio head Xalavier Nelson Jr. pointed out on Twitter that Aloy's hug in the DLC's trailer "is a technical flex." 

If you're not clued up on game development, it may seem like a weird thing to marvel at, especially considering Burning Shores has a lot of other incredibly impressive moments in it - like the too-good-to-be-real clouds. However, as Oud explains in the IGN story, hugs are actually really difficult to pull off when using mocap performers.

As many will already know, motion capture requires actors to perform scenes wearing suits that are covered in sensors, which can be picked up by special cameras and converted into data for animators to use. According to Oud, when two actors hug, the sensors vanish from the camera's view, meaning it doesn't pick up the movement from the actors. To fix this, Oud says developers need to manually go in and correct the mocap data captured during a hug.

This is a time-consuming task and is just one of the reasons why it's so hard to animate hugs in games. Another reason, Oud explains, comes down to what the characters are wearing. The movement captured during the mocap stage is essentially just the character's bodies - meaning things like hair,
