scale map module

Refraction is physically-based:

Sorry for the late response, I had lost track of this thread.

Regarding the offset component for the usage I mentioned:
It seems that when I use the offset component for this purpose it comes up short.

I forgot to fully specify before, but my hopes are for each checkered square to magnify from the center of the region it is over. When I try to do this with offset it seems that the center is always the entire images center.

If I'm not making sense I'd be glad to upload a few images.

Thank you!

Tricky indeed....

Okay so it wasn't rocket science afterall and I figured out how to do this as far as checkered regions go. The checker example I had mentioned was just a simplification of what I really hope to see in FF and that is some way to obtain a similar effect as far as centering goes but with any old map input, not just square regions...

Imagine:

magnification module
input 1 - mag level
input 2 - image to be magnified

Magnification (aka scale) module uses map component's brightness value to determine the magnification level. So that each contiguous brightness region from input 1 will magnify based on it's center the corresponding region of input 2. This way you could have abstract shapes acting as the checkers do in my example..

A way to do the following without all of the complications of the offset module, a way without having to use gradients. That's my hope.

Attached is the checker example.
