@mclarekin many thanks , sorry I am useless at noticing replies on here .. I have a lot of asurf work (a fav formula) always very happy to share any fragments/fractals which interest you ..or anyone for that matter : D please let me know.. (fb gallery https://www.facebook.com/timemit-393093930773750/?ref=aymt_homepage_panel) dA gallery http://timemit.deviantart.com/gallery/)

amazing (no pun intended) .. so is this an asurf module for mandelbulber? is it an included one or a bespoke piece... love to give it a wiggle : )

hey, I am not great at this but in trying to run I get ... .
I remember in some of Crists combo he puts in a DE return statement at the end of the code
Should I run a debug and send you that file?

I don't have DE-Kn8.frag so I tried DE-Kn9.frag
