I’m trying to create the material for a plastic bottle with cycles and can’t really find a good solution. Here are two images for you to look at (3D-Model on the left - actual photo on the right).
The tricky part is that the bottle should be almost transparent in thin areas (blue dot on the 3D-model) and very opaque and milky white in thick areas (red dot on the 3D-model).
I’ve tried to work with the Absorbtion Node that is provided by the BlenderDiplom website (https://www.youtube.com/watch?v=qkqsx951gcg) but this version can only go darker or more saturated in thick areas and I’m not able to go towards white. I’ve also tried to use the Volume Absorbtion Node of Blender, but this has the same problem. It would be great if I had something like the Absorbtion Node Group to control the mix between two shaders. Plugging the Absorbtion Node into the Fac Node of the Mix Shader has no effect.
If possible, I would like to use a solution without SSS, because I’d like to render the scene using the GPU.
Maybe there is some Cycles expert out there who knows a solution.
Thanks in advance,
