actually what he want i think is don't hide the raid frames at all, but limit them to showing 25 member.
Bingo, that's exactly what I need.
to do that, remove the whole function to hide raid frames. and add this to the function starting with "local initObject = function(object, unit)" in oUF.lua.
object:SetAttribute("groupFilter", "1, 2, 3, 4, 5")
Now here is where I am stuck. As a novice, I'm not exactly sure what "remove the function" is. As I am using pUF as a base, there are two files, Core and Layout. Core is where the "local initObject = function(object, unit)" is, and Layout is where I think this 'function' is.
Anyway, I hope this pastey helps.
