hi guys, I got the bugs render region + denoiser too. bormax has explained it well.
and then, DR still doesn't work at all after 1.3 or in all pre1.4 builds. I got "got no response from 3ds max, aborting","DR is finished","Closed loopback connection".. does the DR pre-1.4 builds work in your machines guys? or I'm the only one who experience this... I just switched to 1.3 and it works nicely.
thanx
