Kiinda explaining a little on flowmaps in ue4.
As stated in the video, I've only recently gained some experience about this, and found the few video's I found about the subject either lacking or not informative enough.
That said, I not really happy with the result I created either, so hey! Up mine! I guess :p At least it works properly.
Note: You can find a similar setup in the "engine Content/functions/Engine_materialFunctions02/examplecontent/" folder.
