How do I rotate an image without mirroring- instead show solid color?

[Lindsey Fletcher]

I’m trying to make a video of spinning labels, but I don’t like that when you’re seeing the “back” of the labels, the image is mirrored, if that makes sense. It’s supposed to look like a spinning roll of stickers, so I want the back to be solid white paper- is there a way to achieve this look?

 

I just learned about expressions in a tutorial today, so I’m still pretty new to AfterEffects. I tried searching here but I was probably using the wrong keywords!

For a regular 3D layer, you would apply this expression to an effects that whites out your layer (a tint, or a fill for example):

but in your case it looks like you’re using CC cylinder or something ?

In that case, two layers one that renders the inside, one that renders the outside, and the inside one is made white before the cylinder effect.
