hi all
I have a texture that I use as a SphereMap skybox. but the center of the texture is the ground, how do I rotate the skybox 90 degrees along the x or z axis?

thanks

Are you looking to arbitrarily spin the sky? You’d have to write a custom skybox shader to do that, or not use a skybox material and render your sky as a mesh placed in the scene which you spin.
