So I have an emitter object, emitting the said particles rendered from a collection. They show up in viewport shading with cycles, and when I render with motion blur, I see the motion blur for said particles. But the particles themselves, not a trace (they should remain scattered around after hitting the surface). I've been looking for ways to have them appear. All the collection is enabled for render, I tried baking the particle system before rendering, I tried rendering specific frames for tests and nothing. I've also set the start and end to 0, to a different value, tried particles as unborn, and as dead.. Just very basic falling particles.
The same particle collection is used as hair emission in another object (the proverbial donut), and they do show up in the render. Some images below with the particle system setup. I'm new to blender, and did what I could already for this very first animation, and before making this post. Any help is well appreciated.
