I'm currently modeling a bedroom scene that has very thin curtains over each side of the window. I'm able to make them transmit light from the back side with no issue, however they either cast no shadow or full black shadow.
The curtains are wavy/folded like you'd picture curtains being, and the light is hitting them from an angle that should allow for a shadow to be cast that still shows those folds with a variable density of shadow on the walls/floors.
I've tried editing everything I can think of in the material, combining my Principled BSDF and a Translucent BSDF (as well as trying Transparent) but can't get the shadows to act anywhere close to how they should. I'm using Cycles.
Has anybody successfully created an overlapping translucent shadow before, and how did you do it?
Thanks for the help!!
