Yes, we need to have access to post processing for that. I would like to add a little bit depth of field.
TrackMap.fx is usedin game, but only for changing color on track color in menues.
I wonder if the game calls the technique ColorCorrectionRGB2HSV ?
I have not been able to find the call from the game. If we could add "calls" somehow we could add many interesting things.
I think the screen shader used is called L0screenT0, fvf_screenT0 or fvf_screenspace, but I don't know if that can be used in some way.
Maybe it is possible to hex edit shader name, but I don't know how the format of a screen shader works yet.
