Hi Nirsul,
hmm that's odd !

does it works in low, medium ? crashes only when raising quality to "production" ?
Do u use Max VFB or Vray VFB ?
can you tell me your max and vray version, OS, and RAM please ?

sounds like a ram issue... perhaps have you a vray or max error message before the crash ?

I suspect it is a VRAY SP3 issue as it happens even when not using SR.

BTW - is there a way to have only the AutoWB and Auto Exposure system loaded - for cases that I don't need the SR features except for those ?

Hmm OK, not SR related, but SP3 related. that's bad luck !

about autoexpo and autowb, humm this option don't exists for instance, sorry ;)

but there are only 2 values affected byt these tools :
physcam custom balance color and shutter speed.

i suppose that the good thing will be to add a button into the init/save rollout like "apply cam params" ?

The beauty in the AWB and AutoExposure is the fact that they can detect the correct settings - don't know how you did it...

the feature you suggested is a welcome one thanks.

thanks !!
basically i first launch a minipreview with actual cam settings (except wb, i force white color balance)

then i explore all the pixels of mini preview (depends of alpha options) to make a simple average of all pixel colors.

For example at the end of this process i know that the average of all colors in the preview if a grey 110,110,110.
I suppose that for a good autoexpo this average need to be 128,128,128. So i know that i have to raise the intensity to about 17%. The maths parts are here, converting this percentage in a new shutter speed calculation. was hard to find the right formula.
auto WB was a little bit more simplier, perhaps because i've made it after ;)

next step is an interactive slider to fine adjust the expo before clicking on OK button. that's not simple.. but i'm motivated !!
