Set Camera Focal Point

[woods_cg]

Hi,

It would help a lot to have an option, like in Maxwell or Indigo, to set automatically the Camera Focal Point by clicking on the model.

Also a tutorial about DOF settings would be very appreciated!!

That would be a useful script. As for Depth of Field here is some info I scraped up from http://www.spot3d.com (V-Ray for Max docs)

[*]On - turns the depth-of-field effect on.[*]Aperture - this is the size of the virtual camera aperture, in world units. Small aperture sizes reduce the DOF effect, larger sizes produce more blur.[*]Center bias - this determines the uniformity of the DOF effect. A value of 0.0 means that light passes uniformly through the aperture. Positive values mean that light is concentrated towards the rim of the aperture, while negative values concentrate light at the center.[*]Focal distance - determines the distance from the camera at which objects will be in perfect focus. Objects closer or farther than that distance will be blurred.[*]Get from camera - when this option is on, the Focal distance is determined from the camera target, if the rendering is done froma camera view. (NOTE in V-Ray for Rhino the checkbox next to the Focal distance edit box is used to determine whether the focal distance will be overriden by user input or if it will grab it from the scene )[*]Sides - this option allows you to simulate the polygonal shape of the aperture of real-world cameras. When this option is off, the shape is assumed to be perfectly circular.[*]Rotation - specifies the orientation of the aperture shape.[*]Anisotropy - this option allows the stretching of the bokeh effect horizontally or vertically. Positive values stretch the effect in the vertical direction. Negative values stretch it in the horizontal direction.[*]Subdivs - controls the quality of the DOF effect. Lower values are computed faster, but produce more noise in the image. Higher values smooth out the noise, but take more time to render. Note that the quality of sampling also depends on the settings of the QMC sampler as well as on the chosen Image sampler.

I think another user reported a problem using the DOF in beta 4 - so you may have issues getting certain params to work (I believe the aperture is the trouble param ).
