View Full Version : Post Process volume, Activating it while outside of the area?
12-12-2010, 04:04 AM
Basically i'm making a side scroller and need to use post processing to blur the under water area and create the effect that there is a body of water there. The problem i'm having is that the post processing volume doesn't activate untill the player is inside of the area. Thanks for any help.

You can't do local postprocessing (just a part of your screen) with volumes. Not sure if you can even do this without c++ coding, as you probably would need a new rendertarget to mask out the underwater areas...

Damn, Thanks anyway Xoliul. Does anyone know any other way of creating a body of water for a side scroller instead of just having a fake looking plane of water?

Maybe one plane facing the camera with a distortion shader and another plane facing the sky with a water surface shader (reflection, ripples, etc...).
Both of those shaders would be animated to simulate flowing water...

Don't use the UDK Novemebr 2010 beta. This version have a bug in the post-processing volume (the colorgrading don't work). It's will be fixed in the next beta.

Thanks Ben! Worked great!
Froyok, Really? Damn, I was just about to update, I've a few versions behind so I guess i'll download the october version instead. Thanks for the warning
