Pincushion distortion transform
The current barrel transform is where As I understand it, you use that to transform the UV coordinates you sample from a bitmap. This works fine for deferred shaders. But how is the ...

Your embedded images do not work for me (broken links).

But that is the barrel distortion, isn't it?

The distortion coefficients may need adjusting after switching lens sets, but I did not notice much difference other than FoV using when switching to different lens eyecups. The chromatic aberration correction is not perfect in all cases, making color fringing visible is some areas (especially visible in OculusRoomTiny with all those sharp-edged floor tiles) but it is quite good, IMHO.
There are three pairs of lenses provided. Do they all have the same chromatic aberration?
