DOF and saved solutions

Does (can?) Vray used a saved solution when rendering with depth of field? I was just wondering if it is possible to have a saved solution, perhaps produced for an animation, and then change the DOF settings dynamically without having to recreate a new solution, so that the DOF can vary over time.

It should work, I don’t see why another dof setting would need a different lighting solution.

Yes, you can do that, provided that the DOF effect is relatively small…

Best regards,
