Hey!

I was wondering how one would go about adding shader effects to the camera in karma and XPU?

For instance how would you do raindrops on the lens type of effect like this? [www.shadertoy.com]

I know I can add a physical shader to the camera i LOPs, but would it be possible to use a texture to distort the lens?

Are there any tutorials on this?
Thanks!

I've had this same thought. Not sure if the Lens shaders are the solution to this. Or just projecting a texture map in front of the camera?
