VRAY Grass hopper camera DOF animation
Hi,
I've been playing around with DOF to try and animate DOF focus shift using a simple ball and box test but I'm having trouble trying to replicate the fixed point option in grasshopper.
I created a screen capture video, first part of the video shows a simple grasshopper setup with a DOF focus point, a Target point and a Position point. I thought the DOF focus distance point would be identical to the fixed point option in regular vray DOF, but it doesn't seem to behave the same. It seems to affect zoom as well. I can get it to shift focus from the front cube to the sphere but its physically changing the viewport zoom which I don't want. I just want the DOF blur to shift from the closer object (cube) to the farther object (sphere) and vice versa without the camera view moving. Can't really find much documentation on it either besides some old videos on how to animate flythrough animations but nothing in detail about camera manipulation and camera focus.
The 2nd part of video shows what I actually want to animate, I used the standard fixed point in vray.
