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.
Mostly i am just too lasy to model box around house and camera points. But in the most cases it works, and even more. If you have situation where you have to show godrays then it is better to use box with aplyed vol mat then global volmat. I don't know how that happens but it that case it is working better, i belive it is somehow related to how lightarys bounce trough distance.
