NodeGroup - Light aberration

Hey folks!
I made this node for simulate the aberration light.


This node move the rgb channels in a simple cycles area light.
The result is very interesting… creates borders of different hues.

Enjoy it!

Nice work, thanks for sharing!

That’s pretty cool, but when I try the blend I just get a black screen (in 2.70 and 2.71). Seems to be because one of the nodes in the group is undefined:

What am I missing? (this is inside the OFFSET_CHANNEL_VECTOR node group)

it should work in 2.71
but you can change that node with the ‘combineRGB’, that does the same thing.

That works - thanks. It’s pretty cool, thanks for sharing.
