Salve a tutti, sto seguendo questo tutorial: http://www.motiondesign.biz/ ma ad un certo punto non riesco a continuare. Il punto è questo: Vado nella scheda SGPhong1 e apro la sezione mental ray. Devo assegnare lo Shader Parti_Volume1 alla voce Volume Shader, ma nei materiali nn c'è lo shader Parti_Volume1. Come devo proseguire?
Assing a 'PARTI-VOLUME' Node to the MR Volume Shader-Node

Make this settings:
Scatter: 100% RED ... this one controls the Subsurface color.
Extiction: 0.500 ...( I call it : Caustic - Visibility - Attenuation)
this controls the strength of the Caustics
when they hit the Volume
0.1 is HIGH - 1.0 is LOW
Min_Step_Len : 0.02
Max_step_Len : 0.20
Controls the accuracy
(Don't forget this both !!!)
That's all for the PARTI_VOLUME Shader !
Go back to the Mental-Ray Custom-Shader Tab and apply
a PARTI_VOLUME_PHOTON Node to the PHOTon Volume Shader.

Scatter: round about 20% of the slider !
Extiction: 1.500
Min_Step_Len : 0.02
Max_step_Len : 0.20
