Question: How to import or open .TGC file?

[Rain]

I apologize if this has been covered before, I'm still learning to navigate around.  I've searched and googled but am just not finding the answer.  I have a couple .TGC files, for clouds and I don't know how to open them in TG2 (free version). Can someone point me in the right direction?

Thank you

Sure thing. Go to File.. and then Import Clip file. Then just select the one you want to include to your project. Careful though. They may need to be plugged into something, e.g. the planets atmosphere shader. It won't be done for you.

More or less a beginner here.  I have downloaded some of the .TGC files in this thread and imported into a new project.  The cloud layers come in but don't show up in the sky.
I can't figure out what is going on.  The .tgc files I have imported all look fine in the atmosphere tab but don't show up in the sky.
A little guidance would be nice.
Thanks
