Thin shell transparency settings v8
Fot the thin shell settings for transparency I would really love to see some explanation for the transparency settings. I am trying to create materials for leaves but it seems hard to set things right for how the other side of the leaf looks.
Any help appreciated.

That was covered in
, specifically for plant leaves. Were there specific questions you had, or an effect you are after, that was not covered in that?

And for a quick setup, something like this should do the trick! ;)

Tx, that's a all I needed to know. I went through 20 min.of video...
Its hard to find properly set up leaves on vegetation resources I can buy on the web. Maxtree, Graswald etc all are completely off. Also caused by the conversions to Physically based materials and often overly complex settings that make no difference. It makes buying a library at times a bit of a disappointment for all the hassle to get the materials updated.

Glad it could help!

The transparency setting though also make a lot difference in how a tree looks in its complete rendered image. More so than what you would expect from the transparency. The brightness of color and overal appearance is completely changed by the transparency settings much more than what you see in the video with the example of a potplant.

Hi frv,
I just went through the same thing. Updated some trees to PBR mat and even with "same" transparency, the trees looked very different.
Kind of "dull". I ran out of time to experiment and just went back to legacy.
Did you find a solution for PBR mats? Any tips what to try?

Hi,
look at the video and you will know it all. Its a bit of a long video but I learned all I needed to know. The reason why vegatation looks darker is because the transparancy setting by conversion is way to high. For vegatation it needs to be around 15 to 20 % instead of 50%.
Another thing is that the image texture should be put in color and not at fraction.
Also the glossiness is important. But basicly its very simple to set the texture for a thin leaf right without loosing brightness.
