save VrayLightingAnalysis channel sequence

[s0real]

hi.

i'm rendering out an animated daylight study sequence using the VrayLightingAnalysis render element but i can't save out a multi channel .exr with the light analysis data.

i've managed to save out the multi channel .exr by turning off the VFB, but the VrayLightAnalysis channel renders out black - i'm guessing that this is because the element is calculated in the VFB after each frame has rendered...?

the only way so far i can save out the element is by saving direct from the VFB, but this is going to be problematic on a rendered sequence. is there a way to do what i'm trying to do?

thanks!

edit: max 2020 + vray next 3.1 (4.30)

I just tested rendering such a sequence and saving it through the V-Ray raw image file output. It seems to be working fine. Could you share the scene here or at support@chaosgroup.com so we can take a look (mention this thread in the e-mail)?

Hi - thanks for the reply.

i didn't try using vray raw image file, i was using EXR - i'll try with vray raw image and see if that works.

thanks.

i managed to save out the render channels as separate jpeg files from the vray frame buffer settings rollout which solved the issue. sorry, i hadn't realized that this was an option.
thanks for the help.
