 . This happened before, and when it did, I just restarted Blender and I was good to go. But now it won't go away. I've done a render of the RAC with a stack of tyres and a mirror behind it. There is then two walls to make it look like a showroom. Before I added the walls and mirror, I was getting good renders, that took about 30 mins in HD. But now, it takes 10 seconds in HD, and the quality is gone...The one attached took 4.2 seconds, and the reflection is gone from the floor (It was there before I added the mirror and walls).
