Five-sided Skyboxes?

[iSpook]

I have a slight question: The skybox I plan on using only has five sides (a picture for the top, north, south, east and west portion of the skybox), and I am unable to come up with a picture that'll work well for the "bottom" image... will the game break if I only Define these five images like you would a skybox with the full six sides?

I don't know the answer to your question, but the sixth side is usually just made a solid colour in circumstances like these. Pick a colour that blends well enough and make the sixth side out of that.

Of course you need the sixth face. Otherwise the skybox will be invalid.

I'd do what GooberMan suggests. i.e. just make a black/brown/tan/green/pink/whatever square and use it as the floor. Presumably, given that you don't have a floor graphic, you weren't planning on making it so that the floor of the skybox was actually visible anywhere anyway so a plain floor shouldn't really matter.

If you really wanted to exercise your photoshopping skills, you could flip the side images and use a fade effect to blend them onto the plain floor around all four sides but that seems like a lot of effort for minimal reward and its questionable how good it would look anyway (it would depend on the skybox and other factors too).
