Wouldn't you just draw the clouds on top of the sky?  A simple change in order of operations might be all you need.

Steve, no reason to if you would never see it. The clouds are there 24/7 unless I want to change it. But I would rather not because the clouds are so cool to watch.

@SMcNeill  the clouds are sky and cloud generated by a noise texture routine first discussed here:
https://qb64forum.alephc.xyz/index.php?topic=4615.msg140454#msg140454

Vince made a good mod of some code I translated from Yabasic.

Then Ken probably picked up here:
https://qb64forum.alephc.xyz/index.php?topic=4638.msg140509#msg140509
Where vince included the sky cloud code without labels in Falling letters game.
