How to unlock the Splinter Ray achievement in Rayman Legends - Definitive Guide
From what I could tell, this would not unlock unless you did the entire level straight through without being seen by a light or touching a laser. Going to the last checkpoint to correct a mistake did not work for me. It unlocked on the time when I did the entire level without being seen and without dying.
Some tips:
-Avoid doing anything you don't have to. Focus on the achievement, and not saving the teensies or the lums.
-You will have to sprint at some parts. It's almost mandatory to hold the trigger while you swim.
-If anything bad happens, just exit the level and try the whole thing again.
-Take the top route on the section with the fish on your way back. Don't go near the green flickering light. Even if you think it didn't see you as you ran under it, the game might disagree.

Rushed it a few times and also very slowly... 🤔
From the beggining, i chose the left side first cause between the right and the left ''door'', the left one is harder. After both buttons were pressed and the lasers guarding the central door were disabled, the tricky part beggins.
Keep in mind that you don't have to rush trough this section since the laser traps are pretty easy but they can be very frustrating if you hurry and make a wrong jump or think that you have time to make a pass by one laser. I also made a video using the game dvr and i was rushing trough the level to be sure that my gameplay of this level doesn't get bigger than 5 min, which is the time limit of a video record at this date (hopefully, in a future dashboard update, the limit will be raised to 30 min) and I got extremely lucky at the end. To make sure you don't get touced by the last laser, after jumping from the first ring to the second one, press and you should be safe since none of the lasers can touch you under the last ring.
And after that, ACHIEVEMENT UNLOCKED.
Mansion of the Deep can be found in 20,000 Lums Under the Sea. You'll need to be careful making your way through the level dodging all sentry lights and lasers. If the lights turn red for even a fraction of a second you'll need to completely exit the level and try again, for some reason selecting to restart the level after setting off an alarm or touching a laser can void the trophy.
If you've completed the level and the trophy hasn't popped, this might be your problem:
In the room on the left of the lift, continue on as normal and after turning off the electricity further in you need to head back towards the lift area. In the part where you need to jump up to the higher level to avoid the sentry lights, make sure not to touch the lightbulb that is up there. Even if you smashed it on your first run through that room, if you step on it it will sometimes set off an alarm for a split second (the sentry light below you quickly flashes red) and nulls this trophy. Jump over it and continue on your way.
Also be careful not to fall into the fish tank in that area too, if you fall in here it counts as an alarm so be wary!

In the "Mansion of the Deep" level in the "20.000 Lums Under the Sea" World painting, there will be several lasers and lights through the level. You have to avoid all of them to unlock the achievement. The video below is the best explanation possible:
