is there a shader that for transparent plastic that simulates a hollow inside, as described in this answer, but whose roughness is also adjustable? Using that node setup increasing the density value gives a somewhat rougher plastic but it looks a bit weird and I do not think that this is the correct way to do it

enter image description here

The problem is that using a Glass shader requires the mesh to have an inside and that would be quite hazel to the ad and increase render times drastically. OS I require a material that uses the same approach as in the linked question but with a roughness slider

Thanks for your help

  • $\begingroup$ What kind of shape are you using it on - is it simple like a cube, or more complex with curves and nooks? $\endgroup$ Nov 13, 2021 at 0:07

  • $\begingroup$ Yes, if I want to render the transparent material realistically, build an inside, it will drive up render times and would also increase the poly count. I could try just using a cube as the "inside" but that would still not help with the render times $\endgroup$

Try something like this - it might not be perfect, and may take some tinkering, but you can adjust the clarity/rougness through the Transparency Mix, the Roughness of the Glossy Shader, and the IOR if the Fresnel - between the 3 you should be able to find a mix that comes close. I added a bit of a Noise Texture to some Bump, to give it that "slightly bumpy plastic look" (and I mean very slightly - I mixed the noise texture .999 percent with white first), and I also colored/darkened the glossy and diffuse colors to match the photo. The "magazine" is a flattened stretched cube (6 sides):
