I want to create a simulated rain effect on a character's face.
Hello everyone! I want the particles to leave a mark on the texture, but for that, I need to somehow determine where the particles are located in UV space. Heres an example: https://www.youtube.com/watch?v=F3TkzRwzptYI. Currently, I am using a sample texture for this, but the problem with this method is that the particles stop being dynamic; they just appear and disappear, so this method doesnt work for me. However, I learned that a similar method is used in TLOU2 and found this video: https://www.youtube.com/watch?v=_bbPeCwNxAU timecode: 13:00. From this video, I understood that I need to create a custom module that will allow me to convert particles into UV space using barycentric coordinates, but I dont know how to do this. I would be very grateful if someone could help me write such a module.
