# UsageHints

> Offers a set of options that describe the intended usage patterns of a VisualElement. These options serve as guidance for optimizations. You can set multiple usage hints on an element. For example, if both position and color change, you can set both UsageHints.DynamicTransform and UsageHints.DynamicColor. Note: Set the usage hints at edit time or before you add the VisualElement to a panel. In the case of transition, when it starts, the system might automatically add missing relevant usage hints to avoid regenerating geometry in every frame. However, this causes a one-frame performance penalty because the rendering data for the VisualElement and its descendants is regenerated.
