Is there a way to clamp a fractal with a kind of rolloff?
I'm not that clever with the blue scalar nodes, and clamping a fractal is straightforward, but is there a way to smooth off the transtion of the clamp, to get a rounder edge?
I don't know if a smooth step would help, but I'm not sure how to use it
any ideas appreciated!
Perhaps the new "smooth min/max scalar" functions are of use.
Here's some recent discussion, including a helpful example from Matt:
http://www.planetside.co.uk/forums/index.php/topic,20846.msg207909.html#msg207909
Smooth step takes the input and allows you to set a certain value as a start (say 0.5) and a value as end (say 0.75).
Then the output will be the values from 0.5 to 0.75 of the input remapped to 0 to 1.
Anything below 0.5 will be black (0) and anything above 0.75 will be white (1).
Hope this helps!

thanks Martin, I'll have look at that.
aha! got it working - exactly what I was looking for :)
I was using the soft maximum and also had the inputs the wrong way round
soft minimum works - actually its a very nice effect

sounds exotic...please show us....
There seems to be soo much possibility with these soft max/min scalar shaders.
maybe not exotic, but very useful[attachimg=1]

thanks for the demo file. This really looks quite useful.
