Fluid flowing through linked obstacle I have linked an object from another .blend file that has fluid obstacle physics. I have an inflow fluid object flowing onto it and a fluid domain object surrounding it. 

However, the fluid simply flows through the linked obstacle object. Are there any properties I need to tweak or is this not possible?
Fluids ignore the linked object but you can create a proxy of the object and make that a fluid obstacle.  Sorry.
Hopefully, unlike me, you've moved on by now, and this isn't the worst news you've had all week.
