Dear Richard

I can confirm the graphics proxy to work for both the "floor" and a position model. I don't see a bug here.

I would also like to point out that I prefer to link the proxy to the static floor instead of the mobile position model, to keep to plotting of my particles somewhat steady. If I link them to the position model, they start moving with it, using its base as reference instead of the map.

Kind regards
