Rotational items in skybox not working

Hmm...I have my lost horizon map that has functioning rotational items in it - think tf2_facing worlds for the items/planets.

I copied pasted the entire skybox structure over to my new map and nothing is happening any ideas on why it would work in one and not the other?

They are currently on door entity but I'm thinking of going over to a rotator entity.

thanks, forgot the logic to start it - now if I can get the texture that was there to work (1 of 4) I'll be happy - the texture is a black square the rest have all stayed the same.
