Hello!
Does anybody know how I could create a dust sheet like texture ?
been playing with the prinicipled shader and the glass shader to no avail! its like it needs to absorb all the light and replect only a little with a hint of transparency. but i cant get it to look good.
heres my ref:
and my node set up and render:
Please help 
I think you need to increase the roughness and lower the transmission, remember that thin plastic don’t have a high IOR so play with low numbers like 1 - 1.3.
another test.
Just tweak the settings until you’re happy.
Thanks so much!
Plastic have about IOR 1.45, but if this is thin walled you have to use refraction node with geometry/incoming as the normal, then fresnel mix that with glossy. Current principled can’t do thin walled refraction. The refraction could also be mixed with a mix of diffuse and translucency for a more generalized approach, even if that contributes almost nothing in this particular case.
