Opacity
If your screen looks like a cockpit during a raid night, Opacity is the addon you have been waiting for. It gives you direct control over how visible every part of your interface is, from the world map and your bags to the chat frame, minimap, action bars, unit frames, and even the windows created by your other addons. The idea is simple: keep the screen clean while you play, and get everything back the moment you need it.
What Opacity Actually Does
Opacity does not rebuild your UI or fight with your layout. Instead, it reads the opacity that other systems already assign to a window and multiplies it. That means it never rewrites your Edit Mode layouts, which is a big deal if you have spent hours perfecting your interface. You can lower a frame to 30 percent, and it will smoothly return to 100 percent when your mouse hovers over it, with adjustable fade times and delay.
The addon covers Blizzard windows and interface elements, every TibiSuite module, and the windows of your other addons, grouped by the addon that created them. If you run a heavily customized setup, that grouping makes it easy to see exactly what belongs to which addon before you touch a single slider.
Key Features at a Glance
- Frame picker: hover any window on screen, click, done. The mouse wheel switches between overlapping frames.
- Hover fade: windows sit at 30 percent and come back to full opacity under your cursor.
- Context profiles: separate opacity when AFK, in combat, in a raid, in an instance (dungeon, delve, scenario, PvP), or mounted. For example, everything at 40 percent while mounted and 100 percent in combat. Each window can opt out.
- One-click presets: Immersion and Raid, plus an Undo button.
- Screenshot mode: hides the windows in your list, you take the screenshot, and everything comes back on its own.
- Master slider: scales every value at once, with key bindings for plus or minus 10 percent.
- Profile export and import: back up your setup or share it with friends through a text code.
Compatibility Across World of Warcraft Versions
Opacity for World of Warcraft is built to follow the game across its many flavors. It supports Retail, Classic, The Burning Crusade, Wrath of the Lich King, Cataclysm, and Mists of Pandaria, so whether you are leveling through old content or pushing current-tier content, the addon behaves the same way. Addon compatibility is one of its strongest points: it plays nice with ElvUI and EllesmereUI, leaving the windows they drive alone unless you tick Force, in which case Opacity multiplies their own opacity instead of fighting their fading.
If you manage several versions side by side, the foxygame.net launcher keeps things tidy by letting you install Opacity in one click and keeping it updated automatically across every game client you have configured. That saves you from manually tracking separate downloads for each version.
How to Install and Get Started
Learning how to install Opacity takes about a minute. Download Opacity from your preferred addon source, drop the folder into your World of Warcraft Interface/AddOns directory, and restart the client. Once you are in game, open the options through the game menu or type /opacity or /opa. The slash commands include pick, shot, on, off, options, and reset, which cover almost everything you will need during a session.
Key bindings live under Game Menu, then Options, then Keybindings, then AddOns, then Opacity. Assign a key to the frame picker and you can adjust your interface on the fly without ever opening a menu.
Practical Tips for New Users
Start with the Immersion preset and see how it feels during a dungeon run. If something disappears that you actually need, use Undo and exclude that window. From there, build a context profile for mounted travel at 40 percent and combat at 100 percent. Players who raid seriously often combine a low base opacity with a short hover delay, so frames stay hidden until the cursor genuinely rests on them.
Final Thoughts
Opacity solves a problem most interface addons ignore: visibility is not all-or-nothing. By multiplying existing opacity instead of overriding it, the addon stays out of the way of your Edit Mode layouts and your other tools. Whether you play Retail, Classic, TBC, WotLK, Cataclysm, or MoP, download Opacity and give your screen room to breathe. Your eyes, and your raid frames, will thank you.
