Hi, I’ve been building a set of small experiments around the Screen Position node to learn the materials system in Unreal. The goal was to understand how it works while exploring the possibilities of what screen space effects could be created with it. Each experiment is its own material and takes the concept in a slightly different direction. The experiments are all part of a single project on Github. Dropping the link in case anyone’s interested:
