Read about it hereIf you use the defaults as-shipped in Softimage 2010, you get an undesired 20% ambient contribution,
and your AO will only apply to that light - not your indirect bounce light.

ZAP: "wrong AO default" in MIA
On "zap's mental ray tips"-blog there's am interesting new post concerning the AO settings in the MIA Architectural Material in Softimage, which are said to be wrong...
Stay safe, sane & healthy!
Re: ZAP: "wrong AO default" in MIA
I logged it as a bug two days ago. Let's say it will be fixed soon ;-)
For now it's easily fixed by editing the spdl and restarting SI.
So with the PPG open, rightclick on 'Architectural' above the tabs, and select 'edit...'.
This will open up the editor for the spdl.
So, before you continue, a warning. YOU CAN SCREW UP YOUR SHADER/INSTALLATION WHEN IT GOES WRONG!!
Aannnd.... to continue:
change line 417 till 439 to:
Parameter "ao_dark" input
{
GUID = "{919A2286-4BF9-4CE6-BCB0-166F8A07B741}";
Type = color;
Value = 0.2 0.2 0.2;
Texturable = on;
}
Parameter "ao_ambient" input
{
GUID = "{1873614D-8D28-4F31-9EF8-1485F431A713}";
Type = color;
Value = 0.0 0.0 0.0;
Texturable = on;
}
Parameter "ao_do_details" input
{
GUID = "{860FFEB8-D691-4A32-AEBA-CE265B8A9568}";
Type = integer;
Value = 1;
Texturable = on;
Value Minimum = 0;
Value Maximum = 2;
}
Save the spdl and restart SI. Reopen the Architectural material and the settings should be changed now.

P.S. If -by any chance- things went wrong, don't come to me complaining I didn't warn you

Re: ZAP: "wrong AO default" in MIA
But before you begin, please make a manual copy of the "mia_material.spdl"-file as it resides in your "%sibase%\Application\phenolib\spdl\mibase\"-folder. Just in case!!!
Stay safe, sane & healthy!
