What the areaportal texture itself can do can be compared to that of the cordon tool some of you may have experience with in the past. So please browse through the tutorial section here and read and understand the simple vvis process and hint/skip work before trying these out.Īreaportals EffectThe effect that can be gained by areaportals themselves are among the best if not top tool in which to optimize any level. Especially if this is going to be your first jump into proper optimization, don't want to bite off more than one can chew here as you will just end up destroying your level. While I do suggest that any mapper interested in getting the best performance out of their creations read this tutorial, I still however, encourage you to look over some other basic optimization tutorials on hint brush's / vis leaf editing or some of my previous tools textures to start getting a feel for how delicate some of these systems can be. Nothing wrong with making a section messy and fixing it up afterwords, just make sure you do go back and fix it. Its much easier to design levels with all your optimization in mind first rather than as an afterthought as you will find that brushwork you thought turned out so well then becomes your worst nightmare, now don’t get me wrong its still very possible to optimize levels after the fact, its just more time-consuming and tedious to do in most cases.
Thats why they must be used correctly to avoid these errors. So their use must be chosen carefully otherwise you could wind up in a situation where you have an areaportal brush close and remove a section of the map that shouldn't be removed in another persons perspective if you've placed it very poorly in the open. The I/O triggered open/close states of areaportals enabled on all clients, so a closed/open areaportal in this case will be the same to all users. While the visual effect itself is client sided, the server still controls them. Much like hint brush's and vis leaf effects areaportals are also a client sided effect, where each user will have a different view on whats rendered and whats hidden, so if one person enters an area and the rest of the areas are off to him, doesn't mean another player in another area will have their current spot turn off too. That fact alone makes them useful in several different situations.įor those familiar with hint brush's and vis leafs and what they all are in both the compilation process and final bsp product of a map, much of this will be the same with a few new twists and options thrown in, Be warned, this is a very touchy tool to work with, if not handled correctly you will do more harm than good, at best a failed compile / leak, at worst.well, we won't go there just yet. That is where areaportals come into use, no matter what they will be used as you set them, the engine cannot ignore anything done or set with your areaportals. Tools Texture Use: Part 4 Tutorial Quick Navīrief IntroAreaportals are among the best and greatest of optimization techniques in source mapping, quite simply the strongest and most effective form of breaking your level into many different sub-levels that can be rendered individually with absolute control by yourself where and when this slicing will occur, hint brush's can do this same effect yes, but they are just that, hints for the engine to consider but it may not know the intention in which you placed it there.
