Realistic Earth - Clouds/Atmosphere shows on dark side

Hey guys,

I’ve been going through some tutorials and came across Blender Guru’s ‘How to create a realistic earth’ tutorial and had a crack at it…

Only problem is that once I added the cloud and atmosphere textures into the model and render it this is what I get:


As you can see both the cloud and atmospheric textures show in the dark part of the earth, when in the tutorial video they don’t.

Any idea’s whats happening? and how to correct it?

Thanks, Jamie
