The Group Browser is found at top menubar and is shown with this icon. It's menu allows you to do several things, these will be explained here. New : Here you will be able to create a new group, but at least one item will have to be selected, else an error message will appear like this > You must have some actors selected to create a new group. this action will do the same as the small white sheet icon. Rename : just rename the group, in case you have some groups sharing same objects but except some are not, or if you like to make a duplicate of it. by renaming the group NONE of the items contained in it will disappear nor deleted. No icon is made available for this menu action. Delete Group : will delete that group, you will NOT receive a confirmation message. this action will do the same as the small Red X icon. Note that will not delete any actor in that group, but just release these actors to no group Add selected actors to group : will do the same than clicking the small plus sign icon Add deleted selected actors to group : this is a mistake from the programmers at syntax it should have been > remove selected actors from group and will do the same as clicking the small Minus sign icon. Select Actors : Will select all actors belonging to this group and will do the same as clicking the Red highlighted dotted square. Deselect Actors : Will deselect all actors belonging to this group and will do the same as clicking the Red not-highlighted dotted square. Docked : Docked will dock the Group Browser with the main browser or other opened browsers. for best workaround dock all browsers togheter. This action will do the same as the small multi window icon. Refresh : Now something undocumented, the refresh can be done each time you add or remove items to or from any group by simply clicking on the group after the action. This means, select an item, remove or add it to a selected group, then just leftclick the groupname, that way you will see the action take effect. This group browser may appear of small use or not at all to many users. In fact it is one of the powerfull browsers used by many good mappers or powerusers. I can explain with some examples what you could use it for. just have a look at my "Rebuild fast" page, and you will have an idea of what it can do. Rebuild fast page And now the real reason why it is made for. When you open some map already made by some good mapper, if he left the brushes in it, you will see so many lines that you will ask yourself, how is it possible to work and see what your making with a mess of brushes like this? This is a good start to understand Groups. Mappers use groups to .......... group things like brushes and items just to hide them or show them when they need to work with them. If you have more than one level high in your map, and you want to work on one of these levels separately, you wont obviously unable to work on it, because of the wiremess shown on screen. Unless you first select the brushes and actors from each level and adding them to their appropriate made group. For example you made level one and then selecting all the actors from level one, making a new group that you name "Level one" (for example). Make level two and then selecting all the actors from level two, making a new group that you name "Level two". Now you will be able to hide group "Level two" and see only the actors and brushes from "Level one". This way you will see les lines and more clear what you are working with. You may create a new group for anything you like. It is allowed to create subgroups like this : select all actors for level one, make group "level one". select some actors from within level one and create group "level one ammo", containing only these actors. If you now uncheck group "level one", the actors from group "level one ammo" will be hidden automaticly, because it belongs as a subgroup to "level one". If you uncheck "level one ammo", then the actors from "level one" will be visible but the actors from "level one ammo" will be hidden. You can make interesting gruops like "paths" containing all pathnodes, playerstarts and liftexits. groups for lights or for items like weapons and ammo, that way you can hide these items without having to hide actors, this would be very annoying, hidding actors will also hide items and pathnodes, but also the handles fro the clipping tool, and that would be very difficult to work. So, better make groups for the things you need to hide and unhide when needed. Some console commands for the pathnodes exist like this > PATHS HIDE PATHS SHOW Select all your pathnodes actor select ofclass class=PathNode Select all the playerstarts actor select ofsubclass class=Playerstart Or just to select all the light sources actor select ofclass class=Light Select all movers in your map actor select ofclass class=Mover
