Install the addon ZGOO.
Move your mouse above the bar and write "/zgoo mouse" (without "" ) into the chat, press return key.
A popup window will show you information about the control below your mouse. It should have an entry GetName() which will show a value right of it like "ZO_ExperienceBar.." or something like this.
Note down the name and use a script in the chat like this then:
Code:
/script ZO_ExperienceBarNAmeWhichYouHaveNoted:SetHidden(true)
Try if this works and hides the bar.
Though this will only work as long as you do not open any menu or inventory as closing it/opening it will probably show/hide the bar again.
Edit:
Just checked the control name as I had used it within FCOItemSaver already. It hsould be this name:
ZO_PlayerProgress
So the script to hide it will be:
Code:
/script ZO_PlayerProgress:SetHidden(true)
If you want this permanently into an addon you must define when it should be hidden, and when it should be shown.
I do not use LUI or know why the player progressbar is shown as you are NOT in the menus. Seems LUI changes something there as standard ESO will not show the abr if you are outside the character menus or inventories.
Someone would need to check in the LUI code then (
if there is no setting for it already -> Did you check the LUI settings properly? ) how it get's shown outside of the menus (I guess it will be the HUD_UI_SCENE then) and prevent it again.
