bright images when DR or stripe render

[rjw]

is there any obvious reason why I get far brighter images if I use DR or stripe rendering.
images running on same PCs
ok for screen and BB single images and regions.
I have gamma at 2.2

would like to sort this out for tonight.
1.47.03
IR + LC

Thanks,
Richard

do you have the whole "." and "," thing setup correctly? just a shot in the dark guess

[rjw]

da elf,
not sure what you mean by . , setup?? could be it as I don't get it!

I actually was mistaken, it's only happening in strip rendering, DR ok, the test render had some roof elements missing so looked bright.

[rjw]

going nuts, not sure why but all running ok now?? Was definitely going wrong yesterday, have the images to prove it.
Anyway, please ignore as I now can't recreate the problem.

sorry

Was one VFB and the other one not?

Are you using photometric lights? A problem that I was having that someone here helped me with was that my photometric lights weren't on the network, but only on my local drive causing bright frames on the frames rendered by other computers. That would explain the bright strips using DR. Good luck.

jujubee - for this project I'm not using VFB.
Visualride - no photometric, standard targets with vray area shadows. the lights are excluding some elements and some elements are excluded from the GI.

FYI the strip image was totally bright, no banding visible. the same machines running a single, via BB were normal.

I've had problems before where it seems max applies your gamma correction twice when doing strip renderings; once after the strip render, and then again after it combines the strips.
My workaround was to make sure to uncheck the "delete temporary images upon completion" checkbox in the strips setup. That way if it freaks out you still have your strips, and at worst you can combine them in photoshop, or try re-starting the assembly job in backburner.

From my experience it seems to be 100% random. Out of curiosity are you running backburner 3, or 2? I haven't done any strip rendering in 3 yet, and am wondering if its fixed.

Best of luck!

emptyvoxel,
This is interesting information, sounds like the problem I'm having. many thanks for that.
I'm running BB 2.

Cheers

You can correct this problem in PS using the Exposure tool....
