How?

Using the HDRP, VFX Graph and Raycasts mostly. The Raycasts get the points on the mesh that need a particle to be spawned at. By encoding the position information in a 2D texture, we send it to the GPU (the VFX-Graph). Every particle gets assigned a uv coordinate which represents its position. The uv coordinates position gets set and the particles spawn.
