Transparency lost when exporting to SVG

[SS_9878254]

Hi all

I am exporting my 3D figures as SVG to edit/add lines in Adobe Illustrator and I include image in the export.

Now I experience that transparency of parts is lost after export. 
I recently updated to illustrate 8 from 7 and this was not an issue before, any idea of what setting could course this behavior?

Transparency is fine when I export to PDF or PNG. 

Pictures show difference between view in creo illustrate and the exported SVG in Adobe illustrate.
