WorldEdit CUI Mod FAQ

Make a WorldEdit selection on a server that has the WorldEdit plugin installed, and the outline appears automatically. WorldEditCUI only displays selections you've already made with WorldEdit commands, it doesn't create them itself.

It only works where the WorldEdit plugin is running, which normally means a server. If you're playing singleplayer with a mod that provides WorldEdit-style commands, the CUI can still display those selections as long as the mod sends the same selection data.

Run the WorldEdit command //sel to clear your current selection, and the outline disappears with it. The CUI just mirrors whatever selection WorldEdit currently has, so clearing it in WorldEdit clears it visually.

The most common cause is that WorldEditCUI isn't actually installed on the client, or it's disabled in your mod list. Check that the mod is enabled and that you're on a server running WorldEdit, since the CUI needs both sides to work.

WorldEditCUI has its own config options for things like outline color and whether the selection is rendered as a full box or just edges. These are client-side settings, so they only affect what you see, not what other players see.

Yes, these are exactly the selection types the CUI is most useful for, since they're hard to visualize without a visual overlay. The outline updates in real time as you add points or adjust the shape.

It's a lightweight client-side renderer and normally has a negligible impact on performance. Very large or complex selections with many points can cost more to render, but it doesn't affect server performance at all.

No, the outline is rendered only on your own client. Other players see the actual block changes from WorldEdit, but not your selection overlay.

You can install and run the mod, but you won't see anything unless you have permission to make WorldEdit selections on that server. Without WorldEdit permissions, there's no selection for the CUI to display.

WorldEdit keeps your selection active until you clear it, so the CUI keeps drawing it. Run //sel to remove the selection and the outline will go away.
