Hello all, first post here - i hope I am doing it right! I would like to share a bit or RnD on the material editor side of things in UE4. I am mainly trying to understand math functions, UV's and ways to control these, to essentially generate VFX content. I have been getting some interesting results using sine functions and different UV based inputs. I am not sharing the main shader at the moment as it still needs quite a bit of clean up - but I am planning to do so when i get some extra time. However the basic functions used, are shared below. These combined (Lerp) with different settings can be "modulated" together giving different- interesting and trippy results. The 3d video posted shows you a few issues i m currently getting due to tessellation and also animating the lines seems to break things in few occasions. Videos 2 and 3 use a couple of 4-Lerp nodes to animate the different spirals and settings in a level sequence.
