    Default createing a Tutorial about Importon + irradiance Particle + Final Gather

    Hi Guys,

    I will create a Tutorial about Importon + irradiance Particle + Final Gather importance Sampling.

    I have do Test and i am little confused.

    This setting work at 3dsmax2013 and final gather importance = "partial", if i use "on" it is to dark.

    Importon + FG:
    - importon on
    - use trace depth of Importon to set the Depth Bounce of Final Gather
    - Final Gather Depth Bounce is 0
    - irradiance particle on
    - irradiance particle interpolation always

    Importon + irradiance Particle + Final Gather:
    - importon on
    - irradiance particle on
    - irradiance particle interpolation always
    - Final Gather Depth 1- X ( here set you the irradiance particle passes)

    Is this correct?

    Why comes this messages?
    a) set irradiance depth 0 and final gather depth to 0.
    - if i do this, and all Depth 0, give it no irradiance particles calculation

    b) set irradiance particle depth to 5 and final gather to 0
    - if i set irradiance particle depth to 5 and Finalgather to 0, no irradiance particle calculation.

    Importon + FG set importance to "full" (IP off in this case)

    IP + FG set it to "partial" (Importon assumed from IP)

    FG + more bounces will help take care of more specular interaction that IP does not currently.

    Things to note:

    Scenes like this should render cleaner and with more detail faster than FG or IP alone. However, I have noticed the darkening. You should keep the portal lights for interiors. Brute force (no interpolation) IP or FG isn't quite ready yet with Unified Sampling.

    Not seen those messages yet, hopefully to test more soon.

    Can you share the string options or command line options to do this or is it only possible in Maya 2013 with UI support ?
