spiky thing (sss)

After rendering this with iray in 3ds max 2013 x64 using the sss (sub-surface-scattering) iray material for 49 hours 10 minutes and 35 seconds and reaching 50035 iterations using my amd 8150 eight-core cpu @3.6 to 3.9 ghz, I decided that I had waited enough!

 

(rendering sss materials in iray is really ssslow!)

Done
