Hmmm... updated Dn... white plastic gloss gone, lights less responsive

I'd been using Dimension for a few years - the simplicity and effectiveness worked so well. While the update is an improvement in many ways, some of the simpler effects are either hidden behind sliders elsewhere or counter intuitive? For example, creating a glossy white plastic version of my logo with directional light, casting shadows and reflections was super easy. 

Since the update, I'm struggling to achieve the same effect. Where's the clean, smooth white reflective plastic material we used to have?

Thanks
