This is probably something incredibly stupid that I'm overlooking, but can someone please tell me how to get thin lens working when an object is selected as the focus object? I've looked at the tut here:

and nothing. When I do this, everything goes out of focus. I can't get the focus object to become and/or remain the focal point, and I feel like I've pressed every button at this point. When the focal depth is set to zero, the aperture reads 1.#inf, and then if I change the aperture, the focal depth changes along with it and everything goes out of focus. In focus object, I drag in the target object, but the checkmark box above it for use target object is greyed out.

Nothing works. Thanks for any help.

In the "Thinlens" tab, uncheck "Auto Focus".

I checked and unchecked auto focus. Nada.

Hi,
here is working as expected, the target option is grayed out unless you assign a proper target tag to the camera. Here is an example with the three options in action:

Is the scale of your scene very very small?

My hero product is 6 inches. Is there a lower limit?

I will try assigning a target tag as. That's probably a good idea.

Still not getting it. I feel like a cretin right now. Someone please come and shoot me in the face. I'm literally staring at your example scene, comparing it to mine, and the only difference is that your focal depth in the Octane Camera tag has turned red, where mine just sits there.

Can someone spell this thing out for me, in giant Sesame Street letters?

Hi,
I have revisited your scene, I have changed some parameters in order to better see the effect. Actually the only problem that I see is that if you assign a focus object in the c4d camera attributes, if already active, the autofocus is not turned off automatically, you have to deactivate it manually in the octane camera tag. You see this in the Camera-Sphere, hope that this solve your issue

After some serious experimentation, I actually got it working by dragging the focus depth slider all the way to the right, turning it red, and then was able to control the depth of field with the Aperture Aspect Ratio.
