Quote - Nice effect Noviski, 

I did write 2 spin-off plugins for myself to give the distance and acuteness/edge falloff as separate shaders that return a value.  Looks like you've used the closeness sub-channels as 1 and 0 values to achieve it. 

Should I release these as well ?  I think there are commercially available shaders for fake fresnel and one that does proximity already though. 

 
Thank you, SparrowHawke. I'm trying the proximity effect of MipMapper at water shaders as well, maybe we can simulate the CP6 transparency on CP5. Free plugins are always welcome, and you have a lot of it. If you need a beta tester for your products, I'm totally at your service! :-)
