In this recipe, we will have our first brief contact with organic materials, which is a really challenging topic in computer graphics. We will go more in depth on this in the last chapters of the book, but this will be a good introduction.
It is time to create the material for the plant in our scene. To start, let's select the object named Plant and add a material to it. Name the material Leaf01
and go to the materials' node editor.
To create the plant materials, follow these steps:
Add a Glossy BSDF and Mix Shader node. Set the Glossy roughness to
0.080
and change the algorithm from Beckmann to GGX.Mix the default Diffuse BSDF and the Glossy BSDF with the Mix Shader node. Put the Diffuse on top and the Glossy at the bottom, and use a Fac value of
0.200
. Also set the Diffuse roughness to1.000
.Now, let's add a Translucent BSDF and an Add shader node. Add the output of the previously added shaders and the Translucent node...
