Feature Request: [E] Envelope for focus distance

[johnhorizonvp]

Yeah, it's me again... Can you add an envelope button for the focus distance and/or the ability to link
focus distance to an object like a null? This would be great for rack-focus effects.

You can link a LW constant node to the focus distance to animate the parameter without problem. You can also use the info nodes to compute the distance from the camera to a NULL or other object.

Ah! Thanks!

The info-node and null trick is awesome. Just move the null to where ever you want focus to be and it's done Works a treat.

Here was my first test of it...

I use the same method (2 info nodes piped into the Distance node) for Near Clip Depth quite frequently too. It's brilliant. If I want to use a long lense inside a small room for a cool effect, the NCD removes the near wall, and the null is fully animatable. I love it.
