How to unlock the White Out achievement in Portal 2 - Definitive Guide

This is achieved once you have completed the challenge near the end of Chapter 7 in which you first encounter the Conversion Gel.

EDIT: Thanks to Offscauta for pointing out that the achievement can be missed if you don't complete the level in the correct way. Make sure you use the portals to jump up to the large grilled area down the stairs from the exit to finish the level.

The achievement can be missed if you don't solve it the "right" way. The first two times I did this level I used portals to jump on to the walkway right by the exit and the achievement didn't pop either time. The third time I used a portal to jump to the grilled area down the ramp from the exit and the achievement popped. It also played a bit more story dialogue. My guess is that Valve didn't realise you could miss out that bit of the level and still get to the exit.

In case you missed it, this achievement can be unlocked through Challenge Mode via the free Peer Review DLC.

Chapter: 7 - The Reunion
Level: 3 - Conversion Intro

Progress through the areas until you come to the room with the square pen in the center, with a bent pipe pouring white gel into the pen. Be sure to solve this puzzle by utilizing the angled panels on the outside floor. When you land on the metal platform across the from angled panels, you will trigger another dialog about lemons and the achievement should unlock.

Story related and cannot be missed. This unlocks in Chapter 7, after completing the first conversion gel test.

Although it is story related this trophy is actually highly missable as if you don't land on the platform correctly it will glitch and not unlock. Make sure you here the full speech from this video clip.

(not my video credit to technole)

Story based achievement, unmissable

Not far from the end of Chapter 7. You are introduced to 3 gels. Firstly the blue repulsion gel. Secondly the orange propulsion gel and thirdly the white Conversion gel. This trophy will unlock after you have done your first room or 2 after obtaining the third and final gel.

Story-related. Unlocks after you have completed Pump Station Gamma: Enrichment Sphere 01 in Chapter 7. Can be glitched if you do not appropriately leave the level by landing on the platform upon leaving the chamber to hear Cave Johnson's speech.

Story achievement.

Chapter 7 <REUNION>

Transformation gel is a white gel on which portals can be placed. In a room where white gel is constantly flowing out of the pipe, you need to place a yellow portal under the place where the gel is flowing out, and place a blue portal on the floor in the same pen so that the gel falls outside the boundaries of this pen. Next, use the blue portal ONLY to “move” the gel to the two vertical pillars, which are marked <01> and <02>. Fill both pillars with gel from the inside up to the very top of the pillar <02>, moving the blue portal from one pillar to the other. You also need to fill the inclined surface on the floor to the right of the pillar <02> with gel. After this, climb to the top of the pillar <02>, place the yellow portal on the inclined surface, and place the blue portal as a utility. Jump into the blue portal and the achievement will unlock.
