Portal Pro is a set of test chambers focusing on solving puzzles locally rather than using complex fling techniques. The goal here is that the solutions are hard to come up with but easy to actually do.

Hey everybody. I just wanted to thank everybody who has taken an interest in this mod, especially those who have posted their thanks, comments, questions and suggestions! We're nearly up to 300 downloads so far, with downloaders from all over the world!

I would like those who posted concerns to rest easy, knowing that I've been reading them, and will be fixing many of your issues, as well as some ones I've found internally* in an upcoming version of Portal Pro.

Also, for those of you who are still stuck on a level, a tester and I have recorded and uploaded a walkthrough of every single level onto youtube, and they can all be found here:

And for all of you who have beaten Portal Pro, keep in mind that there are a few challenge maps that will test you even further, but only if you unlock them by finding a special items hidden throughout the game!

* Currently Secret Chamber 2 is unbeatable because you start with a blue-only portal gun. This will be fixed in the next version. In the meantime, this is how you can fix it:

  1. Start Portal Pro with the argument "-console"
  2. Once inside the level, press the ~ key to enter console mode
  3. Type "upgrade_portalgun" and press enter.

I don't know if the Linux Desura client will let you get all the same mods and games, but you'll need to use Wine, or something similar, to run Portal.

This is by far the best Portal mod I've ever played, but there's one bug. Any time there's fire, the flames are missing, with the console full of red errors of not being able to render the sprite. When I look at a particle system while there's fire in my PVS, it lags horribly. Square BTS is practically impossible unless I type the command "ent_fire info_particle_system kill".

I've tried verifying both HL2's and Portal's cache, but neither worked. What can I do ?

I've had this problem too. It turns out some mappers like to overload the fire particle in order to get some other stuff to work. Here's an explanation.
If you've installed a custom Portal map with this fix, it breaks the normal Portal fire. To get it working again, find your particles directory (steamapps/[username]/portal/portal/particles) and delete fire_02.pcf and particles_manifest.txt.

For some reason, right before the main menu loads, the game quits and says that "a Source engine game is required to run mods". What's causing this? I own Portal.

It means you got Portal when it was free and can't play mods. You need to buy another Source engine game with the same Steam account.
