I have two problems. The first is when I use Iray in the viewport, it always renders 5000 frames no matter what I do. It even renders 5000 frames on an empty scene. I suppose I could reduce the number of frames in Render Settings, but I didn't need to do this before.
The second problem is when doing a full render where I use anything except "Scene Only", it converges too quickly and it's all grainy.
Anyone else having these problems? It didn't used to do this. But this started happening about two weeks ago.
