Rivage Guide | How to Solve Greenhouse Constellation Puzzle

Once you reach Access Level 4, you can unlock the Greenhouse through the Lab. Inside, you need to open a locked chest near the shed to get the handle for Jahi's Room. Getting into that chest means solving the constellation puzzle tied to the sky projector controls.

Unlocking Sun Box and Constellation Book

Before you can figure out any star patterns, you have to unlock the Sun Box sitting next to the computer bench in Rivage.

Head over to the main light control panel in the Greenhouse. You will spot a slider switch on the left side and a large rotation button on the right. Keep the left slider set to the Sun icon. Next, press the rotation button repeatedly until the beam of sunlight points directly onto the Sun Box. 

Watch the sun emblem on the front of the box carefully. As soon as it turns green, the lock pops open. Look inside the box and pick up the Constellations Book.

Matching the Constellations

Now that you have the reference book, you need to display the stars across the dome overhead. Walk back to the control panel, move the left slider down to the Moon icon, and hit the large constellation button on the right.

Looking up into the sky reveals three distinct star clusters glowing in different colors: one Green, one Yellow, and one Blue in Rivage.

Open your Constellations Book and flip through the pages. Compare the shape of each colored cluster in the sky to the entries in the book.

At the bottom of each matching page, you will see a specific code pattern tied to that star shape. Take a quick screenshot or write down the exact patterns for all three colors so you have them ready.

Opening the Chest

Walk over to the large locked chest near the shed. The lock interface has three input fields corresponding to the colors you just projected overhead. Enter the green constellation pattern into the green slot, the yellow pattern into the yellow slot, and the blue pattern into the blue slot.

Once you enter all three correctly, the lock disengages, unlocking the Astronomer Achievement. Reach inside the chest to grab the Door Handle for Jahi's Room.

Take it back to the bedroom hallway, insert it into the exposed wall panel, and crank it until the power gauge completely fills up so you can head inside in Rivage.
