Looks lika a known issue (which cannot be easily fixed - if ever) with perspective view and DR rendering (as it is implemented now)

- Are you rendering a perspective view? If so, create a camera to render
- What version are you using? In newer Corona versions there should be a warning if you render a perspective view with DR.

Good Luck

More things I can think of: Do you have camera motion blur enabled an the camera is (slightly) moving (doesn´t look like this exaclty but with extreme settings it may)? Or do you use any camera correction modifier?

Good Luck

don't use motion blur or dof for this render, and with or without camera correct the problem is the same.....

Are you using standart camera or vray camera?

There might be some instalation missing on single node.

Try using debug - retive exr to detect the node wich is causing the artifacts.

BTW. This might be not only camera. It might be also some third party gemetry plugin wich is missing on one of the pc's.

Then you should write a ticket and upload simplified scene to the bugtracker.

OMG you should have posted earlier. Sounds like a problem with the scene or a bug now. And yes, I would open a ticket here:

I think maru will gladly take a look.

Good Luck

Was this ever figured out? I'm having the same issue with a single DR node. No missing plugins/textures. Using 3ds max PhysCamera

I swapped out the PhysCam for a CoronaCam and this fixed the problem
