reading photon's , something funny again :)

I really tried to fix this on my own  but it won't budge...

I tried pretty  much everything  with the geometry  to  fix  it  but  the normals are  fine  and  even  the  new  geometry  I create (simple box) render's  wrong. When  I  change the  topology oft  wall  (merge vertex or smooth)  only the  pattern  change (and it's totally different). Wooden floor  for example reacts when I reverse  the  normals but  other geometry does not.
Photon generation is  fine , because  I was  reusing photon map  and  the  result  differ    when I changed  topology . So  it  must  be  something  with   photonmap()
o_color = photonmap( photonmap, P, Nn "estimator", 200 ,"mindepth",1);

This  is  the  first scene  where  this  happend :  It  was  downloaded  from here :

I rebuild  the  scene when I got  home  and  it suddenly  works just  fine. Tomorrow I will try to see  what  I was doing  wrong but for  now  her's a pretty picture :)

It actually have something to do with photon emission.
Camera's scale  must  be  1,1,1 :)

I've got different results sometimes and the reason was camera scale (camera in a group with some scale on it).  Just something to remind.

This is definitely smth to keep eye on. It can mess subsurface and shadowmaps too.

Re: reading photon's , something funny again :)

Where  can  I change    photon intensity  for  light ? , 
Or where  should I add  this  control ?
I am  using  8  spot lights to simulate  1  area  light for  window (which  is  50 - 40 % faster ) but  then  my  photon energy is 8 times weaker and  I can only change  it  globally when baking.

Re: reading photon's , something funny again :)

isn't  there  anything I can do  to override photon's energy ?

Re: reading photon's , something funny again :)

For now, the only way is to increase light source intensity.
