Q: DOF and Autofocus...

[playmesumch00ns]

Don't know the exact attribute names, but it would go something like this:

create an expression, call it camFocus or something. Assuming you've got a locator called eyeLoc smack bang between the eyes where you want the focal point, and assuming the parameter you want the distance value to go into is called focusRegionScale as you have indicated, the expression would go like this:

float $camToEyes[3];

$camToEyes = eyeLoc.translate - camera1.translate;

float $distance = sqrt( camToEyes[0] * camToEyes[0] + camToEyes[1] * camToEyes[1] + camToEyes[2] * camToEyes[2]);

setAttr camera1Shape.focusRegionScale $distance;


this just makes a vector from the camera to the eye locator, calculates it length and copies that value into the Focus Region Scale attribute of the camera. The reason you want an expression is so it will be evaluated every frame.

There are some melscripts on highend3d.com, which give you a locator for your focal point, bind that to your object.

on www.pixho.com in the toolbox is another script for dof management.
