Render Region problem


The Render Region is coming up in black & white only with just the slightest indication of color and no middle values at all.

Please see the attachments.

Can anyone please tell me how this may have happened and how to correct it?



There is no attachment so no idea what is actually happening in there?


Any chance you created another pass? Render region will use whatever pass is active. A shadow or ambient occlusion pass would look black and white.

You might also try creatiing a new pass with Render Tools (3)/Pass /Edit/New Pass/Empty. Does this happen in a new scene?

Just a thought.
