Attach texture to my skybox without mirrored?

is there any way to attach a texture to skybox without mirrored?
any by skybox, i mean a huge static mesh. shaped in sphere.

or is it any material editor technique to do that?

what i’ve done is followed unreal skydome sample.
and even i drag texture sample directly to emmisive or basic color, it still mirrored.

well i solved it already.
if we use texture sample, it will only fill half of the dome. and the rest will auto mirrored.

change the texture to cubemap. i prefer .dds file, import, and implement it using parameterCube.
it will fill the whole sphere…

How do you do this? I am having the same issue!
