Please help

Hi there!
I’m just a beginner with Blender so I hope you won’t mind my asking a few questions.
I’m trying to use Blender for interior visualisation and for this I need to create a material with an effect of “semitransparant and scattering” fabric. I use area light as the source of light and external renderer Yafray. Is it possible to make such an effect with Blender tools?

You’ll have to drop us a link to a pic. Semitransparent and scattering can mean many things to an artist.

Have a look at the pics in this script for SSS (subsurface scattering) and see if it’s anything near what you mean:
