rollout, a “Depth Of Field (mental
ray)” choice supports the mental ray renderer's depth-of-field
effects. To use this, turn on Enable in the camera's Multi-Pass
Effect group. Also turn on Depth Of Field on the Camera Effects
rollout of the
The mental ray depth-of-field
is exclusive of the multi-pass version of the depth-of-field effect.
The mental ray renderer also supports motion blur for cameras, but
the controls are not on the camera's Parameters rollout: use the Motion
Blur toggle on the Object Properties dialog for camera objects.
This setting has no effect on the default 3ds Max Design scanline renderer.
NoteWhen you use the
mental ray renderer, reflected or refracted light rays do not always
respect a camera's clipping planes (set in the Clipping Planes group of
the Parameters rollout). Also, large clipping-plane values can cause
poor quality in the rendering of shadow maps. To fix this, narrow
the clipping range or use ray-traced shadows.
Sets the camera's f-Stop.
Increasing the f-Stop value narrows the depth of field, and decreasing the
f-Stop value broadens the depth of field. Default=2.0.
The f-Stop can have a
value less than 1.0. This is not realistic in terms of an actual
camera, but it can help you adjust the depth of field for scenes whose
scale does not use realistic units.
