animating skybox

how make a animated skybox.

i want to make a skybox that change every 7min and 30 sec (8 skyboxes in a hour (1 hour=1 day in the game) and whit moving clouds.

The version doesn’t make any difference here. You need a skybox material with two sets of 6 textures and that can lerp between them. I’m pretty sure you can find something like that in the unify community.

As for the clouds, you could do that by adding a layer on your shader but it seems difficult. I advised you try 3D clouds with particles, there is some awesome free exemples, just google it.
