I think best strategy would be to make a blend material consisting of a glass material and a diffuse material and 'weighmap' them both.

I gave it a spin :

Sky + Sun:



material preview:

Here's the .FRY material for you to download: LINK>>> GLASSGLOBE MATERIAL

The material consists of a 'ghost glass' (weightmapped with a B&W image of the earth) and a diffuse white color material (weightmapped with the inverted B&W image).
For more realistic results, you could also try to use a real glass instead of a ghost glass to have better refraction and caustics. Render time will be significantly higher though.

I hope this helped.

Cheers..

Instead of using ghost glass, I tried a 'real' dielectric glass for next image:

Hey Moderator...You have helped us a lot.

I didn't know how to combine the opacity map and the transparency effect where there isn't opacity. I tried to achieve this result but the layers combination in the material editor is a pending task for me.

This has been a complete and hyper-fast tutorial.

I want to encourage to the rest of tusers to contribute to this section...It's really helpful. It's the 60% of a total 3D job.

Thank you very much.

Regards.

There is also the possibility to add a kind of label onto a dielectric ball.

1. Create a sphere with a standard glass material.
2. Duplicate the sphere + 1mm bigger radius and apply a material with the b/w earthmap in the opacity slot.
Choose the color and roughness in the REF0/90 Slots to your taste.

Kwistenbiebel, i see in your render some inteferences (upper part at cuba and the keys Laughing ) which looks like a bit strange.

So, propably the label workaround might be a better one.

Many nice solutions here Smile
So i might as well post mine Wink

What i did is use the BW map, in the roughness slot and inverted it.
