Selection Modes: New, Add, Subtract, Intersect.

This plugin was developed because UE's built-in HUD class selection method inaccurately determines object boundaries. It relies solely on an 8-point bounding box, which is often significantly larger than the actual object. Additionally, PlayerController projection methods are computationally expensive, as they recalculate matrices and other values for every single point.

This plugin efficiently resolves both issues. Additionally, the plugin implements all the logic, various selection modes, real-time selection, and more.

Starting with UE 5.4, the new plugin version is 2.0.

Starting with UE 5.4, the plugin includes a demo level with a pre-configured component to help you get started quickly and easily.

Features:

• Selection Modes: New, Add, Subtract, Intersect (since version 5.2).

• Standard selection and real-time selection every tick (UE 5.4+)

• Touch Screen support (since version UE 5.2).

• Single Click: Selecting one actor if the mouse does not move.

• You can change the color and thickness of the line, and fill the rectangle with color.

• Lock on first click: Click once to start moving the camera and select objects beyond the current viewport.

• First-Click Lock: Once selection begins, you can move the camera to select objects beyond the initial viewport. Note: When moving the camera, the selection origin shifts slightly due to camera perspective.

High performance: selecting 100 actors in 0.06 ms.

Easy to use - no complex setup required.

Example project: Starting with UE 5.4, the plugin includes a demo level, so a separate project is no longer required.
