Description

CanvasGroup renders descendants as a group with color and transparency applied to the render result. GuiEffect (UICorner and UIGradient) under CanvasGroup will also apply to the whole group. CanvasGroup always has GuiObject.ClipsDescendants set to true and all descendants will render within CanvasGroup's viewport.

Important notes:

  • Descendants of CanvasGroup will be rendered as a flattened texture only when the ancestor LayerCollector has its LayerCollector.ZIndexBehavior set to ZIndexBehavior.Sibling.
  • CanvasGroup consumes extra texture memory. The quality of the texture and total memory usage is limited by the QualityLevel of the client. When exceeding the memory cap, CanvasGroup will render as a blank texture.
  • We recommend using CanvasGroup with static sizes, otherwise a new texture would need to be created to accommodate new sizes.
