Determinism doesn't work with Mesh Location

I would like to use Determism to make identical copies of particle systems that form patterns when tiled. This works fine as long as I use a built-in emitter location like a Box or a Sphere: in every instance the particles spawn from the same spots. But with a custom static mesh as emitter location the particles are spawned from random locations. Am I missing something? Is there a workaround?

A workaround is using a skeletal mesh instead of a static mesh. And you can just import a static mesh as skeletal. I hope this doesn’t add too much overhead.

Sadly a skeletal mesh emitter does not work in a packaged build.
