Thanks for your quick reply. Problem in my case is that the lens shift is animated over time (don't ask
) and there's no way to get Fusion to import this.
I'm now trying to import my camera to Syntheyes and from there export it to a .comp file directly.
Maybe Fusion's new USD framework is able to import lens shift from another application, but even then there's currently no way to use it in Fusion (e.g. by exporting Locator3D positions to 2D coordinates for lens flares like I need right now).
