On the wishlist, I would like to add multiple regions that I define before I hit the “Render” button. If I have 4 regions I need to re-render now, I have to render each region and check up when each region is done. Or send 4 regions to my farm. With multiple regions I define each region and hit Render - done

It’s no solution, but I use a pretty solid workaround for this - add a plane in front of and aligned to the camera and apply a black material with alpha -1 on it. You can then do edit poly->cut and draw shapes around the regions you want to render, deleting holes into it before pressing go. Can use whatever shapes you want like this too.
+1 for this technique…it’s even better than a square region as you can draw complicated shapes to only render what is necessary …saving render time
I’ve used http://www.scriptspot.com/3ds-max/scripts/mmregions before to render out odd shaped regions with one click.
I use this a lot as well, but I still would like to have something quicker to setup…
like a ctrl+click in the VFB that alouws you to freehand draw regions.
and a Shift+Ctrl+Click to add a another selection in the VFB.
It happens a lot that I need to render 2 or more differents regions in a frame.
And because my render takes 5-6 minutes to load the render (heavy maps, loads of forest and instances, big xrefs, etc) I’m struggling sometime to know if I will do 1 big region and render A LOT of un-necessarily pixels or if I will fire-off 2-3 regions renders (knowing that for 3 renders for example, it will be 15 minutes of loading only in stead of 5min for 1 render).
And all of this is even worse when using DR…
So yeah, the plane is a good trick, but sometimes it takes more time than rendering regions, the whole point is tying to win man hours in the end…

Hi all,
The ability to set multiple regions for the render camera is in our “to do” list.
For now the workaround posted by cubiclegangster is a great idea.
You can record a macro. run macro, convert to poly, cut → draw regions.
