The VR Player Pawn (BP_VRMANPawn)
I started by setting up the main Blueprint for the VR player character.
The Blueprint structure includes components for the camera, motion controllers (left and right), and likely the VR root component for managing scale and height.
In the Interrogation Scene, we are implementing key changes to the player’s VR Pawn to enhance narrative immersion and visual feedback.
- Narrative Purpose: The Interrogator’s Gear
For the interrogation sequence, the player needs to be visibly wearing specialized equipment—specifically, a hand sensor (a wrist cuff or similar device).
This visual change serves a critical narrative purpose, signifying that the player’s character is now under surveillance or control within the scene’s context.
- Technical Implementation: Material and Mesh Swapping
To achieve this visual transition, the BP_VRMANPawn (or the Level Blueprint for Level 4) will execute the following logic:
Hand Mesh Modification: We are preparing a separate mesh for the player’s hands that includes the 3D model of the sensor device.
Material Swap/Override: The existing hand material on the VR Pawn needs to be replaced or overridden when the player enters this level. This change can be executed by:
Swapping the Static Mesh: Replacing the basic VR hand mesh with the new mesh that has the sensor built-in.
Applying a New Material Instance: Applying a new material to the hand mesh, which includes a texture of the sensor or a special shader effect (like a glowing overlay) to represent the device.
