Hello guys, please can you someone point me to the right direction? I wish to create translucent material for Blossom I am working on, I plan to have backlight light source in background, so some other flower would cast a shadow on foreground blossom elements, so it must be visible also on other side of blossom, please take a look on image attached. Please, which material or setup should I use?

Hi,
assuming that the petals have no thickness, you can use an Universal material, set a light color in Transmission similar to the Albedo/Diffuse color, and set the Transmission type to "Thin Wall Diffuse".

Here. Quoting:
TRANSMISSION
Transmission controls how light passes through a transparent surface and is explained in detail in the "Specular Material" section. See the link here. One difference from the Specular material is the Transmission Type drop down menu, which contains the following options:

Diffuse — Uses the Diffuse value for transmission. This setting will spread out the transmission of light through the surface in a broad manner. Good for simulating textured glass, plastic drop cloth, etc. This is the default value in version 2021 of the c4doctane plugin.
Specular — Uses the Specular value for transmission. Use this setting for clear materials. This was the previous behavior in earlier versions of the c4doctane plugin.
Thin Wall — Uses the Thin wall value for transmission.
Thin Wall (Diffuse) — Meant for thin surfaces such as leaves and treats layers of the Universal material to be independent of the side of the surface. Incoming rays will always enter the topmost layer first.

It is also covered on the website in the form of photo-realistic applied scenario (and soon, available project files).
