I know this modded allows leaves to drop particles, I'm guessing its tag based?
Either way I'm wondering how you are getting that particle, are you generating it to just grabbing it from the particles associated with the block?
If its autogened I'd like to be able to use them in my resourcepack to add more thin leaf piles to immersive weathering, currently immersive just casts the leaf block to a 16x16x0 for the thin model using the direct texture from the leaf block.
If I could manually copy in 16x16 textures using a couple individual leaves generated by this mod I could get

Top row is manually made vanilla leaf piles
Lower left is color variants of oak, spruce, and birch
Lower right is some unique leaves
It could look ✨stunning✨ with me doing more handmade assets with the help of this mod
