Is there a way to adjust the roughness samples in the plastic material anymore? I recently switched from KS5 to KS6, and I don't have the little triangle by roughness to adjust the sample now. I used to use this all the time.
Maybe it's still there and I have to flip a switch in preferences somewhere to make it show up?
The roughness samples drop-down is available with the Plastic (Transparent) material. Just set the specular transmission to black to make the material non-transparent.
