In this recipe, we will create a glassy polystyrene material (which you find on the body of ballpoint pens), as shown in the following screenshot:
The glassy polystyrene material as it appears in the final rendering
First, we need the usual preparation:
- Start Blender and load the
9931OS_Suzanne_start.blendfile. - Select the Suzanne mesh and press T. In the Tool Shelf panel on the left side, select Flat under Shading. Press T again to close the Tool Shelf panel.
- Go to the Object modifiers window in the Properties panel and delete the Subdivision Surface modifier. Add a Solidify modifier and set the Thickness value to
0.0350. Add a Bevel modifier and set the Width value to0.0050. Uncheck the Clamp Overlap item.
Now we are going to create the material by performing the following steps:
- Go to the Material window and click on New (or as usual, go to the Node Editor toolbar). Rename the material
Plastic_clear_polystyrene. - Set the Viewport Shading mode of the Camera view to Rendered.
- Switch the Diffuse BSDF shader with a Mix Shader node, and in the first Shader slot, select a Mix Shader node again. In the second Shader slot, select a Glass BSDF node. Set its IOR value to
1.460. Change the values of R to0.688, G to0.758, and B to0.758. - Go to the second Mix Shader node, and in its first Shader slot, select a Transparent BSDF. In the second Shader slot, select a Glossy BSDF node. Change the Glossy BSDF node color values for R to
0.688, G to0.758, and B to0.758. Change the Roughness value to0.010. - Add a Fresnel node (press Shift + A and navigate to Input | Fresnel) and connect it to the Fac input sockets of both the Mix Shader nodes. Set the IOR value to
1.460, as shown in the following screenshot:
The completed network for the glassy polystyrene material
- Save the file as
Plastic_clear_polystyrene.blend.
