Best GI method for low light interior shots

[tricky]

For interior shots with low levels of lighting, what methods of GI are people using? Typically, for normal renders, I use primary as IrMap and secondary as LC. This tends to produce murky, blotchy low level light renders.

Yup, interior shots with low lighting are the toughest in terms of avoding blotches.

The universal method (Brute force as primary and Lightcache as secondary) produces clean, wonderful renders but is painfully slow.
In the end I tend to use Irradiance map and Lightcache as well and tweak HSph.subdivs and Interp.samples in the Irradiance dialgue until the blotches disappear.

Irradiance Map and LC for me too. Did one low light bar scene recently and had to up the HSph subdivs to at least 128 to get a clean render. Chucking in a few very low intensity vray lights here and there helped clean things up a bit as well.

Under settings, the DMC sampler rollout, did you try to lower adaptive ammount from 0.85 to 0.65 or something? I had problems with dark metals in my scene, but on final render, not the GI, but it might share the setting. I think DMC is shared by everything
