What it does

Boss bars with a matching title color flag are not drawn on the client, and the filter runs on each rendered frame. A settings screen with a live filter tester lets players check which bars a given setting will hide before they play. The server also needs the mod installed, because it sends the title updates that change which bars match. The mod depends on Mod Menu and is open source under the GNU Lesser General Public License v3.0 only. Files cover 26.2 – 26.3, with 1.0.1 for 26.3 as the latest.

Key features

Hide by title color flag
Boss bars whose title carries a chosen color flag are removed from the screen automatically.
Live filter tester
A settings screen includes a tester that shows which bars a filter would hide, before it is applied.
Retroactive title updates
When the server changes a visible title, the bar is hidden on the next rendered frame, since frames render several times per second.
