Glass, translucency, export

Hello,

In designer I'm using translucency and it works just fine in Iray mode. When I'm using the texture in Painter it seems fine except in the material preview pan, the sphere doesn't look like strass but rather plastic with glossy effect.

And when I'm exporting the texture from Painter I don't have the result displayed in the texturing window but the one in the material preview pan.

It seems I hit

- the translucency compatibility problem

- the PBR vs IRay compatibility problem.

I'm struggling to fix it. Help!
