This question already has an answer here:
Does anybody know how to achieve a "simple" opacity material in cycles? I'm fully aware of transparent node and mixing it with different shaders, but that's not what I'm looking for, for various reasons.
I'm looking for a diffuse material that treats all the faces it's applied to as a whole, and just simply reduces their opacity like in Photoshop. Below is a rough example of what I'm talking about:
So what's the main difference here is that with transparency node you can see through the faces and also see all the underlying geometry, and I don't want that. (for aesthetic reasons) What I want is a material like on the right, but without the hassle of different renderlayers and compositing.
I guess this might be too much to ask, but I just feel like maybe it could be done with some crazy node setup in cycles?
