Change on F stop / Radius makes render go all grainy

Hi, When I change Aperture values , even a slight change from default option, makes my render ( render preview as well ) all grainy and full of noise, nothing remains visible. Could anyone help me with this please?


Focus distance value set correctly?

Yeah, the default focus distance of zero will do that :slight_smile: If you work a lot with focus I suggest turning on “show limits” for the camera objects property. I love how you can even do custom shaped bokeh here :slight_smile:

thanks a lot guys, yep it was the default value of focus distance…:eyebrowlift:
