# Blender Renderman - Transparent plastic

I have an object, where I wanted to have specific parts that looks like a transparent plastic.

So I have used the primitive variables to adjust the part that I want to be transparent, and the others that I don’t want to.

I’m using a PxrLMPlastic. But after I tweak all the settings, the material stays like a non-transparent plastic.

The presence parameter is the only one to make something, but it acts like an Alpha channel. When it sets to 0, the material is not visible anymore.

Is there any tips on how to achieve a transparent plastic in Renderman?

• Since the material is non transparent, could you broaden the scope of this question by simply requesting a transparent material setup? – Leander Apr 29 '19 at 21:16
• it's not possible to turn transparent the PxrLMPlastic? – French_FitGirl Apr 30 '19 at 19:23
