Hi,
I've just spend the past couple of hours working through my scene to find the cause of DR which stopped working during the project.
The DR nodes would start to load the scene and then quickly unload and restart.

etc.
I compared the old and new scenes with deduction found the offender.
There are 4 windows in the scene, all had planes that fitted exactly within the windows with a corona portal material applied, a one point in the process I decided to shut out some light, so I just applied a standard corona material to 2 of the windows. In the end it turned out these were the objects that were stopping corona DR from working!! I deleted the geo over the windows put in a new plane to block out the light and hey presto DR works.
I can only think that some sort of tag is applied to the geo when the corona portal material was first applied, and that wasn't removed when the standard corona material was applied and that it messed up. Anyway.. there's the fix, I hope it helps someone else.
