I’ve been baffled for quite a while about the ‘top’ layer of these iris textures (claimed to be procedural):
What I mean is the component that looks like a elastic sheet with holes of variable size poked into it (reminds of Voronoi to some degree). Or might also be called ‘bifurcating strands’, weave, meshwork, whatever. I’m bad with image manipulation, so sorry for the poor quality, but I tried to isolate the pattern I mean:
Can’t figure out how it has been done (which drives me crazy). Any ideas, how would you create that with procedurally with Cycles nodes?
Custom variant reimplementation of Voronoi? Some insanity with duplicated node groups to create branching strands?
Quite a riddle, isn’t it?
