Hi Guys I have A problem : see this Image

Maya 8
Mental Ray

http://www.geocities.com/aljaheem_samet/525.gif

Lights : A directional light As Sun Light + Point Light in the Middle of the Room for Emting Photons Only
photons : around 50,000
GI Acc : 1024 , Radius : 0
FG rays: 1024 , Min and Max radius Zero , Filter : 1
Wall Materials : Lambert and in Mental Ray Custom Shader its has DGS As Material shader + DGS photonic as A photon Shader
render Settings : Production , Filter : Mitchell


i'm totally pissed of because of those Over Bright areas .. If i decrease photon Intensity i get dark room which is not my desirable result and if i Increase the Inetnsity the Result is That ... :sad:
even i tried A Normal Lambert .. I got the same thing

+ as u can See is seems like there is A light coming out from Corner too ... WHAT IS THAT? :D Plz Guys Anyway to Fix That !!!

- Do your walls have a material thickness ? Maybe that helps.
(To check, create an opaque sphere with a Photon shader, place a light with photons inside and look from the outside: Some photons will be visible.)

- Also, your number of Photons might be too low.

-If you can, use Mia-Materials, they are neat and correspond in their brightness to regular shaders, whereas DGS-Shaders are only ~1/3 as bright in their diffuse colour.

- If your scene gets really dark without photons, something strange is going on with all the light coming through the windows.

And just out of curiosity:
Why do you use a point-light with "photons only" from the center of the room?
Maybe a secondory diffuse bounces approach with FG-Only is what you are looking for.
