it sort of strange, when i take a screenshot PP effects are not visible on the shot, same applies to buddies on tr3dgs.
It's not that strange. If you define a visible view in a lower layer or define a view that you use for post-processing you get this kind of thing. I have to switch off certain views, otherwise I only get black screenshots...
Not sure, but I guess it's an engine thing or something having to do with the order in which views get rendered on screen...
