From 2.52 to 2.54, I’ve had no luck following any obvious solution other than duplicating the face and reversing normals. I’m curious if it doesn’t have to be done in a python script telling the engine not to cull backfaces on the mesh, and felt like asking here.
Double sided faces are possible. Just follow the steps as described in my last post in this thread:
… do I really have to do this one face at a time? This can’t be right. It’s only activating ‘Two-Side’ on one face when I tick it, no matter how many faces are selected. I then have to go on and select another face, click ‘Two-Side’ again, ad nauseum… surely there is some obscure, hidden solution to this, or it is a bug…? Huge thanks for the help and reply, though.
Okay, so after failing horribly at trying to figure out my own script, I found the script linked in this thread:

It gives an error in 2.54, but if you comment out the ‘if’ block at the very end you can still access ‘Copy Face Settings’ in the spacebar search menu. And it works! Propagates the settings from the active face to the rest of what you have selected.

Just tried the ‘Copy Attributes Menu’ add-on, and that seems to work fine.
Go to User Preferences and enable Copy Attributes Menu in the add-on list.
Select all faces of the model and check ‘two-side’, which will be applied on 1 face.
Still in edit mode, with the same selection and active face, press Ctrl+C and choose Copy Material.
That’s all.
