Hi all, It's too late for Halloween but oh, well. The actual brain shader uses the free shader tool available at www.losthorizonsoftware.com If you elect not to use that tool you substitue its occurances with the Carrara Spots function within the shader of the brain. The .tif texture maps for the brain are high rez so that final images are usable as art for press production. (which accounts for the file size) Download it. Have fun with it. Mark
