Damn, you noticed! I just couldn't get it right after several renders. When i had the stepwidth limiter and raystep multiplier at higher values, the textures came up on that stone but there was way too much noise and black pixelated areas. When I lowered the values, it looked a lot crisper but then the textures didn't show up on some surfaces. I settled on .02 for both. This version was the lesser of two evils.
