RGBA-Channel separation V1.0

FX and XML

example capx

A shader to split the RGBA-channels vertically and horizontally by a given offset. Inspired by David Clark who wrote this shader for Construct Classic.

Usage:

Put the .fx and .xml file under "Construct 2\effects".

Enter pixel values to shift the desired channels.

The Intensity parameter weakens or strengthens the effect.

You could use this for a simple chromatic aberration effect; just set the red channel to something like 10px and the blue channel to -10px. Add some blur for extra eye candy.

Nice!

Hey maybe the same technique could be used with a red/cyan shader connected to the layers parallax, for a stereo 3d effect?

yeah, it might work if we had some 3d depth to play with. this must be tranlated as a color shift according to screenspace. check out that wikipedia article about anaglyph 3d. in fact, it'll be hard to render 2 different scenes, one for the left and one for the right eye, to create the 3d vision. but try it out, a simple parallax could be possible imho.

edit: anaglyph 3d has been dicussed here, too.

This is very cool! I'm curious what kinds of settings folks are using to achieve a good anaglyphic effect.

I have amblyopia and am pretty much blind in my right eye so...I can't really trust what I see without having to almost completely shut my left eye. Hard to explain but anyway, I'm curious what works best for others.

Thanks!!

Hey mate, wanted to report (again?) that the zip archive is still broken. No probs with the stand-alone files. I'm using WinRAR.
