When I get around to copying the Dolly Effect
for when the player is accelerating, I'll give that a whirl. I think what you're describing might be in the same ballpark method-wise. My ZScript is pretty lacking though so thanks for pointing out the playeractorz thing
P.S. This thread was to be deleted a while ago as Pitch, Please! was retitled Autochthonic Widescreen and combined into ScreeM. However I've found a situation where another shader needs to be loaded between the two and so P,P! will return here again soon (with improvements over the ScreeM version).
