View-Aligned HDRI Lighting

Blender Add-on to keep studio HDRI lighting aligned relative to the camera/view.

---

Overview

This add-on automatically rotates the viewport HDRI lighting so that shadows and highlights stay consistent relative to your camera orientation. It's designed to improve visibility when modeling in Solid or Material Preview modes, especially for architectural modeling, product design, and BIM workflows.

Unlike physically correct rendering, this add-on is purely for viewport shading convenience and does not affect final renders in Eevee or Cycles.

Features

• Syncs viewport HDRI rotation to camera orientation.
• Adjustable light angle offset relative to camera.
• Works in Solid and Material Preview modes.
• User-controlled: starts OFF by default to avoid startup issues.
• UI toggle and slider for easy control.

Installation

1. Download __init__.py and place it inside a folder named View-Aligned HDRI Lighting.
2. Copy the folder into your Blender addons directory.
3. Open Blender → Edit → Preferences → Add-ons → Install… (or manually enable it in the Add-ons list).

Usage

1. Open the 3D Viewport.
2. Press N to open the sidebar → View tab → View-Aligned HDRI panel.
3. Enable the toggle to start syncing the HDRI rotation.
4. Adjust the Light Angle Offset slider to control the default angle of the light relative to the camera.

Notes

• Does not affect final render outputs.
• Designed for viewport shading only.
• Works best for modeling visibility and shadow readability.
