Hey all, this is an issue that made my hair cards very odd last time, i cant work with fibermesh on a 4k document as it lags my PC too Valhalla and back an makes things unworkable, but when scaled re drawn out the hair mesh looks like its got no AA and lost all its detail? Even weirder the image i render outs "Thubnail" will look blurry but then when applied looked fine on some images and not others. A bizarre issue.
Currently the only thing i can think too do is somehow work at 4k? but that seems unworkable.
This is the before vs after scaling.
