grainy IRAY results

Masterstroke

It seams as if some IRAY render processes end to earley. They are still grainy after the render stops. So what to adjust in the settings, in order to get cristall clear renders?

Theer are three reasons for Iray to stop - it's exceeded the maximum time (which you can tell it to ignore by entering a value of -1 in the Progressive section of Render Settings), it has used more than the maximum number of samples (I don't think there is an override, so you would just need to up the value) or it has exceeded the minimum convergence percentage. If your image is grainy it's probably running out of time or samples before it converges - either let it run for longer/more smaples, turn up the render quality, or add more light.
