Unity Chroma Key Alternative To Change and Animate Backgrounds
Learn how to remove and change backgrounds in Unity with our background subtraction technology. We describe a robust alternative for Unity chroma key functionality. It requires no physical green screen and can help you animate backgrounds in Unity using custom images or videos.
Our Face AR SDK is a cross-platform augmented reality platform that supports background subtraction in Unity. It allows developers to create Unity apps with a real-time background changer feature. The background remover works automatically and doesn't require a physical green screen. You can use it as an alternative to Unity chroma key solutions when you need to replace and animate backgrounds for the selfie mobile or web camera.
How to set background changer in Unity
Unity background changer is compatible with face filters and supports multi-face tracking. You can build cross-platform games with face tracking, video chats and augmented reality apps in Unity or even use this feature for mixed reality projects.
How does Unity chroma key and backgrounds subtraction differ
Unity chroma key needs a physical green screen behind a person. The shader then picks and removes a specific color from the background which is usually green. Developers need to avoid colors that match the skin tone so it won’t blend into the background.
Unlike Unity green screen shader, the background segmentation uses a neural network that recognizes not the color but the area which belongs to the person and background. It enables a background removal feature that works automatically, in real-time and requires just a camera.
