michael Posted February 20, 2008 Share Posted February 20, 2008 the help is pretty clear about DOF... Home > Rendering > Depth of Field maybe try it on a really simple scene - the old grid, tube, sphere fallback... once you get something going there, compare it to the scene you're working with...

michael Posted February 20, 2008 Share Posted February 20, 2008 remember that you can select your camera hit Enter in the viewport to bring up the camera handle then hit "z" to change to the focus handle you can put the little red square at the distance you want to be in focus, and use the arrows to determine the 'depth' of the focus...

rdg Posted February 21, 2008 Share Posted February 21, 2008 you should also hit ENTER with the camera selected in the viewport. Right click the camera node in the viewport and choose: Full Frustum Clipping and Frustum handle. Change the F-Stop Value Right Click again: Focus Frustrum Clipping And suddenly the depth of field appears in the viewport. (It is a combination of changing the value and chosen the clipping options.) This sound rather mystical, but I haven't found another way yet. Don't know why and when but sometimes this also clips in the shaded camera view (focused: shaded - out of focus: unshaded) Also the F-Stop values don't match real camera values. I have scenes where a F-Stop of 0.05 produces a nice DOF effect - others need values like 80 or even 1000 ... Georg Quote Link to comment Share on other sites More sharing options...

rob Posted March 11, 2008 Share Posted March 11, 2008 When doing DOF in maya and using a zdepth MR shader I have hooked up some nulls for focus point and depth for interactive use . Rob Quote Link to comment Share on other sites More sharing options...
