Improved Two-Handle Range Slider

Enhanced the two-handle range slider with proper hover and pressed states for both the slider bar and the handles. This provides clearer visual feedback during interaction and improves overall usability.

Improved: Divider Styling with Custom Material

Side-by-side comparison of two UI dividers in Unreal Engine. The top one uses a UMG border and looks pixelated. The bottom one is using a custom material-based divider with improved styling.

Replaced UMG borders with a custom material to enhance visual quality, styling, and flexibility for slim UI dividers. Unreal Engine’s default borders often appeared pixelated when used with narrow elements. The new material resolves this issue and supports real-time control over sharpness, color gradients, and dynamic adjustments during play.

Synchronized Hover States for Labels

Two-way communication between UI list items and POI labels. When a button is hovered in the list, the corresponding POI label reflects the hover state, and vice versa. The Game Instance acts as a centralized mediator for synchronized visual feedback.

Expandable POI Labels on Hover

Hover-based label behavior for POIs. When the user hovers over a screen space label or POI geometry, the label expands to reveal the full name, improving readability without cluttering the scene.

Optimized POI Label Opacity and Rotation

Replaced the constant per-frame (Tick) distance and opacity calculations from the original ArchViz Explorer with an optimized hybrid approach: Timer-based distance checks: The distance to the camera is now updated at fixed intervals (e.g., every 0.5 seconds) to reduce unnecessary calculations. Smooth interpolation: Opacity transitions are handled by a lightweight Tick function using interpolation, ensuring […]

Block Input Propagation on UI Elements

Prevents unintended camera movement or interactions when the user starts a touch or mouse drag on a UI element (like a panel or border). Blocks input from reaching the PlayerController by using overrides (OnMouseButtonDown / OnTouchStarted). This ensures the Input system doesn’t respond when the user is interacting with the interface.
