This feels like such a basic question, but I can't work it out. I need to render a semi transparent Lego block and see the back faces of the block.
I'm using Eevee in Blender 2.8 and have created a Principled BDSF texture with a mix shader and a Transparent BDSF. I'm passing an RGB node with black colour (I tried white too) into the Transparency BDSF. I am seeing transparency, but I can't see the back faces and cant find an option for 2 sided material or mesh in this version of blender.
How do I do this please?
