Long Jump Achievement Problem

[Oli]

I've left Chell jumping through portals for over an hour and still no achievement. WHY???

Did you LAND a single jump for 300 verticle?

[Oli]

no, it was a perfect flow.

[ΛLCHΣMIST]

make sure you jump into the portal, have it perfectly lined up and make sure you have portal funneling enabled. good luck :)

I never jumped and got the achievement. Look up and shoot blue look down and shoot orange then walk away for a few minutes. Ding achievement unlocked.

Exactly, I got it in the turret arena in the escape. It took about a minute and a half and probably six portals to get it. I've seen videos of the wall portal jumping bit and never got it that way...
