glass mosaic material

[erva]

is there a way to reproduce the thickness/depth of a glass mosaic tile in a material? i can't seem to find a tutorial or a material of that sort. https://cdn3.volusion.com/3ua53.wm7vn/v/vspfiles/photos/160-GC004-2.jpg?1432638537 as you can see, the grout is droping a shadow. is there a way t achieve this - not with defuse but actual texture thickness of some sort? and by a material i mean not individual geometry - but a texture for wide areas.

cheers

Displacement, normal map, bump...?

I am not sure what the material is like in real life - is it transparent glass and the shadows are visible below it? If so, I would guess some combo of bump map, diffuse map, refraction map could help here, but it might be very tricky. I might try that myself later.

Here is one idea. It only uses displacement and everything is procedural. Keep in mind that this is just an illusion that the shadows are "below" some layer. This is very dependent from lighting.
