You can switch between two post processing shaders either with Lua or using the sliders.
One of these could be replaced to do the effect you’re looking for.
I did a ‘fish eye’ shader that looks like it has a similar effect, will dig it out and see sometime. Presently I have GG in bits on the table as experimenting with loading high poly assets so won’t be really soon.
Cheers.
