Hello everyone !

I'm trying to do a picture of a child in a tente and i'd like to have some light from the outside entering and lighting the tissue. I tried using thin walled and sss but the result doesn't really work as the pattern of the tent fade and the light isn't like ' gradient ' on the tissue.

Here is a screen without the thin walled

And here is an idea of what i'd like to do

Thanks !
