Hello, can you double check that “Particle Shaders” folder and all the files inside of it was imported in your project.
Unfortunately I didn’t build these shaders myself. A friend built these shaders for me. I actually know very little about making shaders.
If you’re unable to get it working in amplify, then I’m more than happy to give you a refund since it didn’t serve your needs.
Please let me know how things turn out.
