How to put a skybox into Roblox Studio
- Step 1
Get the six images
Open a skybox, click Roblox ZIP and unzip it: SkyboxBk, Dn, Ft, Lf, Rt and Up as PNGs.
- Step 2

Home tab → Assets → Import, pick all six, upload as Images. Wait until the thumbnails show.
- Step 3
Add a Sky
In the Explorer hover Lighting, click + and choose Sky. Select it.
- Step 4

For each face type rbxassetid:// plus the number from the ID column into the property with the same name.

Untick CelestialBodiesShown on the Sky.
- Step 6

Which file goes where
SkyboxFt
Front, −Z · What the default camera looks at.
SkyboxBk
Back, +Z · Behind the camera.
SkyboxLf
Left, −X
SkyboxRt
Right, +X
SkyboxUp
Up, +Y · The zenith of the panorama.
SkyboxDn
Down, −Y · The nadir, under the ground.
If the sky looks wrong in Studio
A face is rotated. Roblox applies no rotation of its own, so a face that appears turned means that image was uploaded to the wrong property or rotated on export. Check the face table above, rotate the PNG if needed, and upload it again.
A face is blank or grey. Either the image is still in moderation, which clears within a few minutes, or you pasted a Decal ID. Decals wrap an image with a different ID; upload the PNGs as Images and copy the image ID instead.
A visible seam. Seams come from mismatched neighbours, usually Left and Right swapped. Swapping the two asset IDs fixes it without re-uploading.
A second sun or moon. The Sky object draws Roblox's own sun and moon on top of your images. For stylized skies set CelestialBodiesShown to false on the Sky.
Prefer a single panorama for another engine? The same skyboxes are on the main skybox page with Three.js, Unity, Unreal and Godot notes.
Roblox skybox FAQ
What format does a Roblox skybox need?
Six square images, one per side, assigned to the SkyboxBk, SkyboxDn, SkyboxFt, SkyboxLf, SkyboxRt and SkyboxUp properties of a Sky object under Lighting. The Roblox ZIP here contains exactly those six files.
What resolution are the faces?
Library skyboxes convert to 1024×1024 faces from a 4096×2048 panorama; generated skyboxes give 720×720 faces. Both upload fine as Roblox Images.
How do I upload the images to Roblox?
In Roblox Studio click Assets in the Home tab of the ribbon (Asset Manager under View in older versions), click Import and upload the six PNGs as Images, not Decals. Once moderation clears, right-click each one, Copy ID, and paste it into the matching Skybox property of the Sky object.
Can I still see the Roblox sun and moon?
Yes, by default the Sky object draws them over your images. Set CelestialBodiesShown to false on the Sky if they clash with a stylized skybox.
Does generating cost anything?
