UWidget::SetRenderTransform

function UMG Blueprint Since 4.7

#include "Components/Widget.h"

Access: public Specifiers: UFUNCTIONBlueprintCallable

Description

Applies a 2D render transform (translation, rotation, scale, shear) to the widget. The render transform is cosmetic only — it moves how the widget is drawn without affecting layout or hit-testing bounds.

Caveats & Gotchas

• The render transform is purely visual and does not affect the widget's layout size or position in the widget tree. Child widgets and siblings are laid out as if no render transform exists.
• Hit-testing uses the layout geometry, not the paint geometry. A widget visually shifted by a large translation can still receive clicks at its original layout position.
• The pivot point for rotation and scale is controlled separately via SetRenderTransformPivot. The default pivot is (0.5, 0.5) — the widget center.
