you need to copy the id at the end and replace a decal page on roblox with that id

@rmod8 i tried doing it, but it keeps redirecting me to page 404. i even tried it with different skyboxes. what do i do if that fails?

If you go to the Lighting section in Roblox Studio, you should see a sky object in their, click on it and look in properties, each field is a decal.

@rmod8 yeah, but how to make it into 6 seperate images like what you do before with roblox skyboxes. does it work like taking seprate pictures of the roblox skybox you want?

Roblox and Source share the same way to do skyboxes, which is using 6 seperate images. Simply make VTFs of those images, then make VMT files in the "materials\skybox" folder of the game which point to those VTFs.

The VMTs must all have the same name except a small 2 letter combo at the end which designates it's position. You can see specifically how to name them on this https://developer.valvesoftware.com/wiki/Skybox_(2D)#Creating_a_Custom_2D_Skybox_Texture

Rmod, theres a question i have on porting the roblox skyboxes to hammer. how did you manage to do them since the skybox has to have 6 textures for them. its a question im having because of me working on a port of a roblox map.
