Avoiding Screen/Add overlay of smoke/fire at rendering?

[AdZanetti]

When partitioning and using a box fall off, FFX seems to screen/add overlay the light intensity of each grid on top of each other when rendering? Is there a way to avoid this. SO far i have to render each grid separately in order to be able to overlay the smoke/fire without additive mode at post.

THanks,

A.

Hello,

N-Sim should work flawlessly, not sure about just using falloffs.
