offset for skybox

currently i an using the sky box in my project.i want to rotate the the sky box so that it feel like cloud is moving.

i tried by putting sky box in another camera and rotating the camera but it is not looking fine in my project(looking odd in my project).

i do not want the moving cloud in particles. and tried the sky dome also it is not working for me.

so i want to rotate the skybox by changing the offset value.so that is will give a feeling of moving cloud.

so can u please tell how to rotate the skybox with out rotating camera.

Skybox is actually a cube. Thus you can create your own rotatable skybox. Map your new cube with your skybox textures. Scale it large enough (scale needs a adjustment due to texture size/quality). Use a background shader or unlit shader, using wrong shader will lead to self-shadowing and destroy the illusion!!! Animate rotation.
