Pixel Art + 3D camera: wavy antialiasing effect

Hi guys, hi Chris.

I'm creating a pixel art point-and-click game in Adventure Creator, with 3D camera integration (Game Camera + Game Camera 2D).
Initially I was using the original pixel art images with no filter, to avoid image blur when scaling. I later noticed that with this kind of camera follow I end up seeing a sort of "wavy" effect, especially when the camera slows down and settles. I researched the issue online and it looks like I am not the only one with this kind of problem with Unity + Pixel Art. There are some "camera snap to pixel grid" scripts, but that's not a solution for me.
Also, I don't believe it's an Adventure Creator related issue.
I ended up solving the problem exporting images @20x (still very small in terms of kb: exported at PNG 24 bit or PNG 8 bit) and applying Bilinear filtering in Unity's Texture Inspector. This way I can have crisp pixel art, no blur and no antialiasing problems due to camera micro-movements. Is it too much of an "extreme" solution? Am I missing something?

Thank you,

Aldo

    As you say, it's not an AC issue as such - and if it doesn't affect the game size much I'd say it sounds fine.  IIRC there's an experimental Unity-made pixel perfect camera that you can find on the forums somewhere atm.
