@Sleepybunnzz There is materials but in a separate folder, If you can't find it, unzip with Winrar, 7zip or anything else than Windows's built-in decompressor (it sucks)
im not sure how the og creator made that but my first guess would be poi yomi pro grab pass? you can add a blur like that and also refraction, i have no clue if lil toon can do that but i bet it could. for poi yomi just select the grab pass option and check out the documentation here:
