# renderGroupID

Strokes with certain inks (such as marker) can composite to look as if they were drawn while the previous stroke with the same ink was still wet. This UUID may be set to a single value for a run of strokes which should be rendered together in this manner.

## Declaration

```swift
var renderGroupID: UUID? { get set }
```

## Mentioned in
