I'm making a little isometric low poly scene, and I'm using a couple of hair particle systems to scatter trees randomly over a plane. On my system I have them distributed pretty much how I want them to surround a little cabin I've modelled.
However, when I upload them to Render Street for final rendering, the trees are in an entirely different place. I have rendered it twice and they render in the same location each time on Render Street, but in a different place to my local version.
I also have an emitter system for smoke and that renders identically to mine.
Why is this happening, and is there some way I can 'bake' the hair particle distribution in so it's consistent?
EDIT: The following support page on Render Street goes through baking for particle systems, but this only seems to apply to Emitter systems. There is no cache tab for Hair systems:
