I used to use TD's Dirt shader all the time and loved it, but it doesn't work with v9.5 (causes crash on render). I've been toying around with Grit 3 and no matter what I keep getting nasty artifacting in the form of either black or white lines running across the render. I don't want to use ambient occlusion, as it seems to be light dependant. Anyone know of a good access shader out there?
