I am trying to make a material similar to this unanswered post: Creating a colored translucent material for Plastic/PVC roll
I tried the suggested methods and was unsatisfied with the results. I am most interested in recreating the effect that occurs at the edges of the material.
Below are two screenshots of my current setup that is giving the 'best' results, but is unreal as I use two materials for the one object. Top left in the image editor is my reference image of the desired material look. Bottom left is my super basic node set ups for the face material. the other image shows my edge material. Right is the plastic strip rotated 45º to show the edges backlit by a spot light 50W. I placed a Suzanne behind to test the material transparency. I am using a HDRi environment texture and a power 1 sun lamp to also light the scene.
Does anyone have any ideas how to make the material look more like the reference image? Ideally, using one material? I can use either eevee or cycles for this project.
