![]() ![]() An example of a FACS rig being exercised can be seen below. Despite being over 40 years old, FACS are still the de facto standard due to the FACS controls being intuitive and easily transferable between rigs. The one we use is called the Facial Action Coding System or FACS, which defines a set of controls (based on facial muscle placement) to deform the 3D face mesh. There are various options to control and animate a 3D face-rig. The framework described in this blog post was also presented as a talk at SIGGRAPH 2021. In this post, we will describe a deep learning framework for regressing facial animation controls from video that both addresses these challenges and opens us up to a number of future opportunities. This is particularly challenging at Roblox, where we support a dizzying array of user devices, real-world conditions, and wildly creative use cases from our developers. ![]() Despite numerous research breakthroughs, there are limited commercial examples of real-time facial animation applications. However, animating virtual 3D character faces in real time is an enormous technical challenge. When a user tries to add the Glue texture in Roblox Studio, it turns into the Weld texture.Facial expression is a critical step in Roblox’s march towards making the metaverse a part of people’s daily lives through natural and believable avatar interactions. In 2015/2016, Glue was removed and was replaced with Welds. Texture of Weld when trying to apply Glue. This will tear the bricks apart, leaving the side with Glue exposed. Glue doesn't hold together, say for instance a destructive object interferes with the texture. It could have also be applied to Surfaces in the Properties window of the object, with labeled surfaces. When they selected the surface to apply it to, the Glue texture would appear. When a user selected the Glue button the icon would appear with a hand with crosshairs pointing to a yellow brick. By using it, a user could have held multiple bricks, parts, constraints, seats, solid models and more. The apply button was located in a toolbar near the top of Roblox Studio. Glue was a type of surface that could hold together two parts. This article is about a discontinued feature. ![]()
