Getting a decent-looking wood floor has always been a problem for me. So when I saw this, I jumped on it.
This was pretty much "borrowed" directly from Warp's tricks tutorial
#declare PlankNormal = normal { gradient x 2 slope_map { [0 <0,1>][.05 <1,0>][.95 <1,0>][1 <0,-1>] } scale 2 }; plane { y, -.25 pigment { wood color_map { [.4 rgb <.9, .7, .4>] [.6 rgb <1, .8, .6>] } turbulence .5 scale <1, 1, 10>*.5 rotate y*20 } normal { average normal_map { [1 PlankNormal] [1 wood .5 slope_map { [0 <0,0>][.5 <.5,1>][1 <1,0>] } turbulence .5 scale <1, 1, 10>*.5] } rotate y*20 } finish { specular .5 reflection .2 } }
