Mental Ray Render View different from Batch Render

#1

hi there

i’m rendering a scene with volumetric lighting and physical sky.

my preview render is correct - the batch render is wrong (lighting incorrect).

:banghead:

i’ve tried using this workaround:

but that doesn’t seem to work either.

can anyone shed some light on this.

thanks
