Just to confirm - it is the LOWER Irradiance Cache slider on D3D's render settings dialog that you set to 100 to put Fireflyin in the brute force mode.  Then tweak the Samples as required.

In the brute-force case, there is no initial indirect light calc - and I'm not seeing the SSS calc output (it's black).  There is a substantial rendered difference (SSS wise) between IC 99 and IC 100 (100 has much less red).  I wonder if the SSS pass needs the Irradiance Cache to work properly?

Strange things were also happening for me in the SSS pass, when I set IC to 100.

Well, I say that... all I mean is that the SSS pass output looked very different. So perhaps when IDL is enabled, SSS does rely on it??

Clearly SSS works without IDL, so any condition must only be active if IDL is on? (and no other lights are present perhaps).
