Optical Vignetting incorrect #190

Open zpelgrims opened 4 years ago

Unsure why, seems correct in front of focus dist, but incorrect behind it?

Did some testing with real lenses, and the bokeh should be occluded in the same way for both cases. I can easily switch this for the bidirectional version, since I know if the image of the object is in front or behind the image of the focuspoint.

In the forward version however.. not sure
