Installation

Blender 4.2 or newer.

Install

Install the zip file. Do not unzip it into Blender's folders by hand: a hand-copied folder has no Uninstall button and can misbehave.

Easiest:

1. Drag redlight_studio_kit-x.x.x.zip onto the Blender window.
2. Confirm the install prompt.

Or:

1. Edit > Preferences > Add-ons.
2. Open the dropdown in the top-right corner and choose Install from Disk...
3. Pick redlight_studio_kit-x.x.x.zip.
4. Tick the checkbox next to RedLight Studio Kit.

The panel appears in the 3D Viewport sidebar. Press N and open the RedLight tab.

Update

Install the new zip the same way, over the top. Blender replaces the old version. Rigs in your existing files keep working.

Uninstall

1. Edit > Preferences > Add-ons.
2. Find RedLight Studio Kit and expand its row.
3. Click Uninstall.

No Uninstall button?

The add-on was copied onto disk by hand instead of installed from the zip. Untick it in Preferences, quit Blender, then delete this folder (<version> is your Blender version, for example 4.5):

• Windows: %APPDATA%\Blender Foundation\Blender\<version>\extensions\user_default\redlight_studio_kit
• macOS: ~/Library/Application Support/Blender/<version>/extensions/user_default/redlight_studio_kit
• Linux: ~/.config/blender/<version>/extensions/user_default/redlight_studio_kit

Optional setup

In Preferences > Add-ons > RedLight Studio Kit you can set:

Setting	What it does
HDRI Folder	A folder of .hdr / .exr files. They appear in the HDRI grid.
Gobo / IES Folder	A folder of gobo images and .ies profiles. They appear in the Gobo & IES grids next to the 32 bundled IES profiles.
License Key	Optional. It identifies your order for support. The add-on works without it.
