Visible from only one side

Im a complete noob.
So I downloaded this package https://assetstore.unity.com/packages/3d/props/clothing/accessories/masks-pack-2-157577

what I’m trying to do is have the inside of the mask as transparent while the front is visible.

I tried moving the camera around and even opened the shader in notepad++ and played with the cull setting but still not working.

I tried searching around and didn’t get any answers to work.

I was hoping someone here could point me in the correct direction.

Thank you

Don’t really understand what your trying to do but you could just turn off the renderer when your behind the mask.

Since the backside of the masks are modelnd , you would need to use a shader that allows transparency and then you would need to create / modify the texture of the mask to have a alpha channel ( depending on what shader you use) that defines what area should be transparent.

If you only need it to be transparent that a specific camera can look from the backside , it might be a option to have the mask on a separate layer, then exude that layer from the camera behind the mask.

That way you would avoid issues with the parts of the mask that are in fron but still visible from the back if you use transparency.
