The real entity limit is about 2048 (with a lot of complexity, since some entities count or don't count, as well as count to different limits). In addition the PeTI instances have to use a lot t more entities to be as flexible as they are. As an example, cube droppers use about 20 entities (with the optimised BEE2 version). But in Hammer, you could get the count down to 4 (the dropper model, the cube, a respawner, and a logic entity to manage everything), but only if you knew a bunch of things about the dropper - that players won't be able to point a funnel at it, or push cubes back into it. It's not misleading. PTI maps are programmatically generated from a set of instances and are therefore incredibly inefficient, hitting brush and entity limits by doing basic things.
Jan 10, 2014 Not having to play through the whole chapter to reach the level you want. This method doesn't count as a cheat so you will be able to get achievements. The ability to reload a map again and again till you get the achievement you want. In order to get where we want we will use console commands, so.
2048 is the engine entity limit, but you'll generally want to keep at least 100 below it to give plenty of room for any engine-created entities.The in-game editor is nice to have and allows for some quick prototyping, but it's no replacement for the real editor. If you're hitting limits in PTI, I'd usually cut it down enough to start compilation, take the VMF created for the compilers and open it in Hammer, then strip out all the logic and brushwork that is inefficient or unneeded.Hammer and PTI are on completely different levels. PTI is a sketch-up style tool to quickly and simply create levels to share on the workshop, whereas Hammer is the tool used to construct all of Valve's games from Half-Life to CS:Go. Hammer is an old program for sure, but it's still the best way to create maps and environments for the Source Engine.
A watch in the style of Aperture Science's finest test labs, courtesy of GladOS. Now with upcoming calendar events! Yep, I only had the last advanced chamber unlocked after I finished the game. You don't need to finish a chapter to unlock advanced maps. I went back to unlock some of them, and you only need to finish the test chamber, not the complete chapter.-DZJB.
