Global volume mtl
Really natural look and a great break from the usual over saturated color pallets of in your face arch-viz. Love it.
Doesn't GlobalVolumeMTL override imply, that there is fog inside the house? Ever tried to excluding it?
Since Camera in VolumeMTL doesn't work, I guess the only way is to make a huge box and boolean out the House and exclude the bounding box of the camera. The result would only be a subtle change I presume, but would make the inside a touch more contrasty and punchy.
